Bird Flu Undercounted in US Dairy Cattle: Farmers Avoid Testing Due to Economic Fears

Why are US dairy farmers skipping bird flu tests? Learn how economic worries might be hiding the true number of cases. Curious? Read more now.

Summary: What’s really happening on America’s dairy farms? A startling undercurrent lurks beneath official bird flu numbers. Dairy farmers across the U.S. are avoiding tests, driven by fear of economic setbacks and skepticism about the real threat of the virus. Since March, the USDA has identified bird flu in 190 dairy herds across 13 states, but experts believe this is just the tip of the iceberg. Joe Armstrong, a veterinarian from the University of Minnesota, estimates the true number of affected farms could be three to five times higher due to widespread underreporting. With cases in states like Colorado, Michigan, and Minnesota likely being significantly undercounted, the lack of comprehensive testing poses a severe risk to both the dairy industry and public health. Terry Dye, a farmer from Colorado, confessed, “Sometimes it’s more convenient to not know.” The reluctance to test isn’t just about ignorance or distrust; it’s about survival. Farmers fear a positive result could mean devastating economic consequences, including quarantine measures that restrict their ability to sell milk or cattle. The FDA has found inactive bird flu virus particles in 17% of U.S. dairy products, though pasteurization ensures these products remain safe for consumption. As the USDA prepares to expand bird flu testing, the question remains: will farmers participate, or will economic fears continue to cloud the true scope of this outbreak?

Have you ever wondered why avian flu in dairy cattle isn’t making as much news anymore? The truth may startle you. Farmers around the United States are skipping testing owing to economic concerns, resulting in a significant undercount of cases. While we have 190 official positive herds, there are many, many, many more farms that are impacted or infected that are just not testing. The results of testing restricted government incentives, and decreased monitoring undermined the United States’ capacity to react to possible human spread.

Fear, Mistrust, and Misconceptions: The Real Reasons Behind Farmers Shunning Bird Flu Testing

Why would farmers risk the health of their herds and the public by not testing for bird flu? The answer could be more straightforward. 

  • Economic Hardship: For many farmers, the financial consequences of a positive avian flu test exceed the advantages of early diagnosis. When an epidemic is verified, milk and cow sales restrictions might last many weeks, if not longer. This stop in sales may result in a heavy financial load, making it impossible for farmers to continue operations. Many farmers are hesitant to test their herds due to the possibility of economic hardship.
  • Distrust in Government Incentives: Farmers distrust the government’s compensation plans. Many believe the incentives and financial assistance do not fully compensate for the significant losses sustained due to testing and possibly positive findings. Farmers are skeptical of government help and hesitate to employ testing techniques even with incentives.
  • Perception of Risk: Another significant component is how people perceive the infection. Some farmers do not believe the avian flu poses a substantial danger to their dairy cows. This attitude is based on disinformation, the absence of observable signs in their cattle, and a historical emphasis on bird populations as the major worry. As a result of this view, many people avoid testing because they believe the dangers are minor or nonexistent.

Industry Experts Warn: The True Extent of the Bird Flu Outbreak in Dairy Cattle Might Be Alarmingly Underreported 

Industry experts have expressed grave worries about the understated severity of the avian flu pandemic in dairy animals. These experts encourage a deeper look at the figures concealed behind limited testing and farmer reticence.

Joe Armstrong, a veterinarian and cattle specialist at the University of Minnesota, provides a sharp viewpoint.

‘While we have nine certified positives, there are many, many more farms harmed or infected that are not being tested.’ Armstrong’s findings show that the number of infections may be substantially more significant than reported, maybe three to five times the statistics in Minnesota alone.

Phil Durst from Michigan State University has similar ideas. He believes that Michigan’s statistics are likely an underestimate.

‘Michigan’s 27 positive herds are likely an undercount of at least one-third.’ This troubling disparity demonstrates a more significant trend of underreporting and the need for more stringent testing standards.

Jenna Guthmiller, an associate professor of immunology at the University of Colorado, concurs, citing significant gaps in the reported instances.

‘Colorado’s 63 positive herds are also likely an underestimate.’ Guthmiller’s findings emphasize the urgent need for more monitoring and openness.

These expert viewpoints provide light on the vital issue of avian flu underreporting in the dairy business, implying a far more significant problem than current data indicate.

Farmer Reluctance: Delaying the Inevitable

A Colorado farmer, Terry Dye, encountered the unpleasant reality of avian flu when his two dairies were afflicted this summer. His first efforts to handle the matter privately to prevent governmental action were unsuccessful. “Sometimes it’s more convenient not to know,” Dye confessed. Eventually, state agricultural inspectors discovered the diseases and confined his animals, implementing the steps he intended to avoid.

In Kansas, Jason Schmidt expressed a perspective that many in the sector shared. “There’s plenty of dairy farms that I’ve heard about that just don’t believe it,” he told me. This skepticism about the virus and its consequences adds to a reluctance to do testing, prolonging the cycle of underreporting.

Meanwhile, veterinarian Mark Hardesty summed up a typical attitude among dairy farmers in Ohio with a harsh saying. “The long-standing proverb is that the remedy for fever is not to take a temperature. So, if we don’t test, we aren’t positive,” he said. This approach reflects a larger aversion to proactive testing and the difficulties in determining the exact scope of the epidemic.

The Long-Term Economic Impacts of Ignoring Comprehensive Testing

Ignoring the requirement for extensive testing may save some short-term expenditures, but have you considered the long-term economic consequences? Failure to detect and manage avian flu early on may result in bigger, more destructive epidemics. These outbreaks may shut down whole dairy-producing areas, affecting farmers and supply networks.

  • Widespread Quarantines: Imagine mandatory quarantines that prevent the movement of milk and cattle. This scenario isn’t just a nightmare for individual farmers; it has the power to weaken regional economies.
  • Decreased Consumer Confidence: Consumer confidence could plummet if word gets out that bird flu is rampant in the dairy industry. Lower demand leads to lower prices, affecting everyone from farm owners to grocery store suppliers.
  • Market Volatility: Sudden outbreaks can lead to unpredictable market conditions without proper surveillance. Prices can fluctuate wildly, making planning and managing farm operations challenging.
  • Regulatory Consequences: Governments might impose stricter regulations and testing requirements, leading to higher farm operational costs and potentially driving smaller operations out of business.

Consider the broader picture: it’s not just your farm at stake but the entire dairy industry’s stability. Procrastination on proper testing could turn manageable issues into industry-wide crises.

Revolutionizing Bird Flu Surveillance in Dairy Cattle: The Path Forward 

There’s a clear need to change how we approach bird flu testing in dairy cattle. To better control the spread and ensure public safety, the following measures should be considered: 

  • Mandate Raw-Milk Testing: More states must follow Colorado’s lead and implement mandatory raw-milk testing. This would help identify outbreaks sooner and contain them more effectively.
  • Increase Compensation: Higher compensation for farmers is crucial. It can offset the economic hardships they fear when testing positive, making them more likely to participate in testing programs.
  • Improve Education: Better education efforts are needed to address farmers’ distrust and misinformation. Clear, factual information about the risks of bird flu to cattle and humans can help build trust and cooperation.

Learning from Global Leaders: How Other Countries Effectively Manage Bird Flu in Dairy Cattle 

The U.S. is not alone in grappling with the challenges of monitoring and controlling bird flu in dairy cattle. Other countries have faced similar outbreaks and have adopted different strategies to manage the situation more effectively. 

  • European Union: The EU has strict regulations for monitoring and controlling bird flu among livestock. These include mandatory regular testing and rigorous biosecurity measures. The EU compensates farmers adequately to encourage timely reporting and transparency. These measures have helped EU countries maintain tighter control over the spread of the virus.
  • Japan: Japan experienced significant bird flu outbreaks and responded by implementing comprehensive monitoring systems, including mandatory testing and culling infected animals. The Japanese government works closely with local farmers to provide financial support and education on best biosecurity practices, fostering a culture of cooperation and compliance.
  • Australia: Australia proactively approaches managing livestock diseases, including bird flu. They leverage advanced technology for real-time surveillance and state-wide reporting systems to track outbreaks quickly. Farmers receive substantial compensation for economic losses, encouraging them to report and test without fearing financial ruin.

These international examples illustrate how coordinated efforts between governments and farmers, strong financial incentives, and robust surveillance systems can lead to more effective management of bird flu outbreaks. The U.S. could benefit from adopting similar strategies to enhance bird flu surveillance and control measures.

FAQs: Common Concerns and Misconceptions about Bird Flu in Dairy Cattle

Imagine the financial blow of losing half your herd in a single night. As a dairy farmer, your cattle are more than just animals; they’re the backbone of your business. Each cow represents income, milk, and pride. But have you considered the potential dangers lurking in their pasture? How often do you check up on your herd’s health? Are you confident they’re free from hidden threats? Today, we’re diving into the severe issue of ergot poisoning. This unseen danger could be right under your calves’ hooves, risking their health. 

Ergot poisoning can reduce milk production by up to 50%. Mortality rates in cattle affected by severe ergot poisoning can reach 10%. And the economic impactErgot contamination in pastures can lead to annual losses of up to $100,000 per farm. Let’s uncover this threat and protect your herd—and your livelihood.

First Things First, What Exactly Is Ergot? 

First things first: what precisely is ergot? It is a fungus that develops on some grasses and cereals, including rye. While it may seem just another plant issue, this tiny intruder delivers a decisive blow.

Dairy cattle absorb ergot-contaminated feed, which contains harmful chemicals known as ergot alkaloids. These poisons have the potential to cause serious health problems. You may find that your cows are producing less milk, growing slower, and experiencing reproductive issues. This is not something to take lightly.

Ergot poisoning has long been a significant worry. In the Middle Ages, it induced a disease known as “St. Anthony’s fire” in humans, which resulted in agonizing symptoms and, in some cases, death. Even though we’re far beyond those days, ergot poisoning remains a serious concern in agriculture today. Outbreaks in recent decades have been a solid reminder to practice diligent feed control.

So, how do you safeguard your herd? Understanding the hazards and identifying symptoms early on is crucial. Monitor your feed supplies by regularly inspecting the fields and storage areas. Take proactive steps to avoid contamination, such as rotating crops, keeping storage areas dry and well-ventilated, and conducting regular feed tests. By being vigilant and proactive, you can significantly reduce the risk of ergot poisoning in your herd.

The Silent Signs of Ergot Poisoning You Can’t Ignore 

  • Reduced Milk Production: One of the first signs is a drop in your herd’s milk yield.
  • Lameness: Keep an eye out for any unusual walking patterns or difficulty moving.
  • Behavioral Changes: Agitation, restlessness, or unusual behavior can be red flags.
  • Circulatory Issues: Symptoms like cold extremities or swollen limbs can indicate poor blood flow.
  • Gangrene: In severe cases, extremities like tails and ears might show signs of gangrene.
  • Digestive Problems: Reduced appetite, diarrhea, or other gastrointestinal issues.
  • Respiratory Distress: Difficulty breathing or labored breathing could be symptoms.

So, How Does Ergot Sneak Into Your Cattle Feed? 

So how can ergot get into your cow feed? It all begins on the field. Ergot is a fungus that mainly affects grains and grasses. The fungus replaces the grains with intricate, black structures termed sclerotia, which are subsequently incorporated into the collected feed. Rye, wheat, and barley are especially sensitive. However, ergot may also attach to grasses such as fescue and brome.

This fungus invader’s affinity for precise climatic conditions makes it very difficult to control. Ergot thrives in relaxed, moist conditions. A wet spring followed by a chilly summer produces ideal conditions for ergot development. USDA research found up to 20% of cereal grains may become infected with ergot under favorable climatic circumstances.

Isn’t that shocking? And it’s not just about losing some of your feed crops; there are also health dangers to your cattle. Ergot contamination may be prevalent, and without careful monitoring, these poisonous sclerotia might end up in silage or hay. Regular feed testing is required to guarantee that your cows are not unintentionally consuming this fungus pest.

Ergot Poisoning Isn’t Just an Invisible Threat; It Can Wreak Havoc on Your Dairy Production 

Ergot poisoning is more than an unseen concern; it can devastate dairy productivity. Do you ever wonder why your milk production isn’t reaching expectations? Perhaps there’s a hidden culprit. Ergot poisoning can reduce milk production by up to 50%. Additionally, mortality rates in cattle affected by severe ergot poisoning can reach 10%.

Ergot reduces volume and lowers milk quality. It may cause milk to have less fat and protein. Non-compliance with quality requirements might reduce your product’s appeal to purchasers and result in fines from commercial milk processors.

The economic hit from ergot poisoning can’t be underestimated. A reduced milk supply means less revenue and poor milk quality could lead to losing contracts or needing pricey treatments. Typically, a dairy operation dealing with ergot contamination might see annual losses between $10,000 to $50,000, depending on the severity of the issue. These economic losses can sometimes climb to $100,000 per farm yearly. That’s a hefty sum, especially for small to mid-sized farmers already working on razor-thin margins. These financial hits can seriously impact the health of your farm’s finances, making prevention and control of ergot poisoning an essential part of your farm management strategy.

Ergot Poisoning: A More Common Issue Than You Might Think 

Ergot poisoning is more prevalent than you would realize. Research discovered that around 10% of dairy cow herds in the United States exhibited indications of ergot poisoning (https://www.extension.umn.edu). Even more concerning, some areas have reported a prevalence rate as high as 20% (https://www.sciencedirect.com). These findings underline the need to be cautious against this quiet menace hiding in your livestock feed.

Prevention and Control: Your Best Defense Against Ergot Poisoning 

Ergot must be prevented and controlled. So, what can you do about this? Your actions can make a significant difference in protecting your herd and your business.

First and foremost, check your fields frequently. Ergot grows in humid environments and on certain kinds of grasses and cereals. Be cautious, particularly during the rainy season.

Rotate your crops. This simple procedure may minimize the likelihood of ergot infection. Various crops aid in the breakdown of the fungus’ lifecycle.

Check your feed before it reaches your livestock. It is about what grows on your land and what you bring to the farm. Choose reliable vendors and carefully verify their credentials.

When it comes to storage, keeping your feed dry is essential. Ergot thrives in wet situations, so keep your storage spaces well-ventilated, dry, and clean. Inspect these locations regularly for the presence of mold or fungal development.

Chemical treatments and interventions are available to lessen the consequences if you suspect contamination. Activated charcoal, for example, may bind toxins in the stomach, reducing absorption. Always consult your veterinarian before beginning any therapy.

Taking these precautions protects not only your cattle from ergot toxicity but also your dairy output and bottom line. Why take the risk when prevention is so simple?

The Bottom Line

Ergot poisoning poses a subtle but severe hazard to your dairy animals. We’ve covered everything from understanding what ergot is to identifying the subtle indicators of poisoning, how it ends up in cow feed, and how it affects dairy output. Prevention and control tactics are your most powerful partners in this war.

Being proactive and alert may mean all the difference. Regularly monitor your feed, be educated, and respond quickly if you observe any signs in your herd. After all, your livelihood is contingent on the health and production of your cattle.

Have you examined your feed and cattle’s health today? It may be time for a deeper look.

H5N1 in Dairy Cows: How Pasteurisation Ensures Milk Safety and Prevents Health Risks

Curious about how pasteurization keeps milk safe during H5N1 outbreaks in dairy cows? Learn how pasteurization can protect you from health risks associated with contaminated milk.

Imagine starting your day with a fresh glass of milk, only to discover it might carry the dangerous H5N1 influenza virus. Recent outbreaks of H5N1 in American dairy cows have raised significant public health concerns about milk safety. However, the process of pasteurization, which effectively kills influenza viruses, including H5N1, provides a reassuring safety measure. Unpasteurized or ‘raw’ milk, on the other hand, can still carry infectious viruses, posing significant health risks. Understanding these safety measures is crucial for preventing a potential adaptation of the H5N1 virus to humans, which could lead to a new pandemic. With this information, you can make informed decisions about your dairy consumption and help spread awareness about the importance of pasteurization. Wondering how this impacts you and how to ensure your milk is safe? Read on.

The Threat of H5N1: A Cross-Species Concern 

H5N1, known as avian influenza or bird flu, is a subtype of the influenza A virus. It originates in wild birds but can spread to domestic poultry and other animals, causing severe disease and high bird mortality rates. 

While wild birds often carry the virus without symptoms, domestic birds like chickens and turkeys can experience severe illness and high death rates. The virus has also infected mammals such as foxes, bears, and seals, usually from eating infected birds or drinking contaminated water. 

Human cases of H5N1 are severe but rare, with around 900 infections reported, mostly from close contact with infected birds. These infections can cause severe respiratory illness and have high fatality rates, raising concerns about the virus mutating to spread between humans. 

H5N1 is a significant threat to both animals and humans. Its potential to jump from birds to humans and possibly mutate for human-to-human transmission makes it a global concern. Ongoing surveillance and research are critical to managing these risks and preventing future pandemics.

Widespread H5N1 Outbreaks in American Dairy Cows: A Wake-Up Call for the Dairy Industry 

Recent H5N1 outbreaks in American dairy cows have shaken the dairy industry, sparking severe public health concerns. The U.S. Department of Agriculture reports that 36 herds across nine states are infected, highlighting the widespread issue. This highly pathogenic strain has jumped from birds to mammals, risking dairy cows and milk safety. 

Detection: Researchers have found the H5N1 virus in milk from infected cows through rigorous testing, necessitating stringent safety measures in milk processing. 

The impacts on the dairy industry are significant. Farmers face economic hardships from quarantines and potential herd culling, while consumer trust in dairy products wanes over contamination fears. 

Public Health Concerns: Experts warn that H5N1 in cow milk raises the risk of zoonotic transmission, primarily through unpasteurized milk. While human cases of H5N1 are rare, they can be severe, and the possibility of human-to-human transmission emphasizes the need for control measures

These outbreaks underscore the importance of scientific measures like pasteurization to ensure public safety and protect the dairy industry.

Understanding Pasteurization: Methods and Benefits

Pasteurization is a heat treatment process that eliminates harmful microorganisms in milk by heating it to a specific temperature for a set period. This process effectively kills bacteria, viruses, and other pathogens, making the milk safe for consumption. 

  • Low-Temperature Long-Time (LTLT): This method heats milk to 63°C (145°F) for 30 minutes and is commonly used in smaller dairies.
  • High-Temperature Short-Time (HTST): This method heats milk to 72°C (161°F) for at least 15 seconds and is often used in large-scale operations.

These treatments kill pathogens in the milk without altering its taste or nutrition. The high temperatures break down bacteria and viruses, making the milk safe to drink.

Groundbreaking Collaborative Research Confirms Pasteurization Effectively Inactivates H5N1 and Other Influenza Viruses in Milk

A collaborative study by the MRC-University of Glasgow Centre for Virus Research explored how well pasteurization kills influenza viruses in milk. They mixed different flu viruses, including H5N1, with raw and store-bought whole milk, then heated them to 63°C and 72°C. The result? These temperatures effectively kill the viruses, making the milk safe to drink.

The study’s findings could be more timely. Researchers confirmed that standard pasteurization temperatures of 63°C or 72°C effectively inactivate all tested influenza viruses, including the high-threat H5N1 strain, making the milk safe for consumption. 

Conversely, consuming raw or unpasteurized milk in areas with H5N1-infected dairy cows poses significant risks. Raw milk can carry infectious influenza viruses, including H5N1, which is already known to harbor various pathogens. This highlights the crucial role of pasteurization in safeguarding public health and underscores the need for caution in dairy consumption.

Expert Opinions on Pasteurization and Risks of Raw Milk Amidst H5N1 Outbreak 

Renowned experts have voiced their perspectives on the significance of pasteurization and the associated risks of consuming raw milk amidst the H5N1 outbreak. Professor Ian Brown, the group leader of avian virology at The Pirbright Institute, emphasized, “While infection with high pathogenicity avian influenza virus in dairy cattle is confined to the U.S., we must support global efforts to understand the disease better, the risks it presents to the public and its control. This study on pasteurization provides important information that underpins disease preparedness and response beyond the U.S., should it be required.” 

Ed Hutchinson, senior lecturer at the MRC-University of Glasgow Centre for Virus Research, echoed these sentiments, highlighting the urgent need to confirm pasteurization’s efficacy. He noted, “We urgently needed to answer whether pasteurization made milk safe. We have now shown that the temperatures used in pasteurization should rapidly inactivate all influenza viruses. However, we also found that ‘raw’ or unpasteurized milk can carry infectious influenza viruses.” 

Both experts stress that raw milk can harbor various pathogens. Hutchinson adds, “We would caution people against drinking it in areas where cattle might be infected with H5N1 influenza.” He further warned, “Human infections with H5N1 influenza viruses can be hazardous, and they also give the virus more opportunities to adapt to growing in humans with the chance of becoming able to transmit to humans. Pasteurizing milk in affected areas is a good way to minimize these risks.

The Critical Public Health Role of Pasteurization in Combating H5N1

The findings of this study have important public health implications. Pasteurization is crucial for safe milk consumption and plays a significant role in preventing zoonotic transmissions like H5N1. This process effectively inactivates dangerous pathogens, reducing the risk of the virus adapting to humans and possibly causing a new pandemic. This emphasis on pasteurization’s role should make you feel more secure about your dairy consumption. 

Public health authorities play a crucial role in advising against the consumption of raw milk in affected areas. Their guidance is based on the understanding that raw milk can pose significant health risks, especially in regions with H5N1 outbreaks among dairy cattle. Raw milk is already known to carry various pathogens, and H5N1 increases these dangers. The study supports rigorous pasteurization protocols to safeguard against current and future public health threats.

Global Implications of Pasteurization: Safeguarding Public Health Against H5N1 and Beyond

These findings are crucial not just for the American dairy industry but globally. Influenza viruses like H5N1 can cross species and potentially trigger pandemics. This research shows that pasteurization is vital in making dairy products safe, inactivating H5N1 and other flu viruses, and impacting global dairy practices and health policies. 

Understanding how influenza viruses behave under different conditions is vital for global disease preparedness. Insights from this study can help countries enhance their response to potential H5N1 outbreaks, supporting efforts to control zoonotic pathogens. 

These findings also stress the need for vigilance in regions where raw milk consumption is daily and poses health risks. Promoting pasteurization globally can help protect both animals and humans from future outbreaks.

The Bottom Line

Ensuring the safety of milk through pasteurization is crucial to mitigate the risks posed by the H5N1 virus. Pasteurization effectively inactivates influenza viruses, including H5N1. However, consuming raw milk remains a significant hazard, especially in outbreak areas. Pasteurized milk does not carry infectious influenza viruses, while raw milk can be a carrier. This demonstrates the necessity of heat treatments. 

Understanding pasteurization and its benefits, as well as expert insights from leading researchers, makes it clear that pasteurization plays a critical role in disease prevention. This collaborative research supports established food safety practices and ongoing efforts to protect public health from emerging zoonotic diseases. 

The study highlights the need for vigilant monitoring and strict biosecurity measures worldwide. While H5N1 is currently more prevalent in avian species, its introduction to U.S. dairy cattle reminds us of the virus’s potential to cross species and the risks to human health. 

Ultimately, this research advocates for the continued and rigorous application of pasteurization. It urges consumers to avoid raw milk in outbreak-prone areas to reduce the threat of H5N1 infections and safeguard public health. Stay informed, stay cautious, and prioritize safety in your dietary choices.

Key Takeaways:

  • H5N1 outbreaks in dairy cows raise significant concerns about milk safety and potential human infections.
  • Pasteurisation at standard temperatures (63°C or 72°C) can effectively inactivate H5N1 and other influenza viruses in milk.
  • Raw or unpasteurised milk can carry infectious influenza viruses, posing serious health risks.
  • Human infections with H5N1 are rare but can be extremely severe if they occur.
  • Researchers urge consumers to avoid raw milk in areas affected by H5N1 to minimize risks of infection.

Summary:

The H5N1 influenza virus outbreak in American dairy cows has raised public health concerns about milk safety. Pasteurization, a heat treatment process, eliminates harmful microorganisms in milk by heating it to a specific temperature for a set period, making the milk safe for consumption. Unpasteurized or ‘raw’ milk can still carry infectious viruses, posing significant health risks. Understanding these safety measures is crucial for preventing the potential adaptation of the H5N1 virus to humans, which could lead to a new pandemic. H5N1, also known as avian influenza or bird flu, originates in wild birds but can spread to domestic poultry and other animals, causing severe disease and high bird mortality rates. Human cases of H5N1 are rare, with around 900 infections reported, mostly from close contact with infected birds. Recent outbreaks in American dairy cows have shaken the dairy industry, highlighting the widespread issue. Researchers have found the H5N1 virus in milk from infected cows through rigorous testing, necessitating stringent safety measures in milk processing. Consuming raw or unpasteurized milk in areas with H5N1-infected dairy cows poses significant risks, as raw milk can carry infectious influenza viruses, including H5N1, which is already known to harbor various pathogens. Promoting pasteurization globally can help protect both animals and humans from future outbreaks.
