The U.S. is in the midst of the worst outbreak of the highly pathogenic avian influenza—otherwise known as HPAI or bird flu—on record. Since it was first detected in December 2014, the deadly H5 strains have caused the mass culling of millions of birds, devastating poultry and egg farmers all over the country. Here are eight things you should know about the outbreak and how it might affect you.

1. How many birds have been killed?
To date, more than 47 million birds have been killed, a shocking 80 percent of which are egg-laying hens. It has also been detected in commercial and backyard turkeys, chickens and other types of poultry and, most recently, wild geese. The numbers have escalated to an unimaginable degree—it was only two months ago when there were fewer than 1 million reported cases, the Washington Post pointed out. You can check the latest numbers on this web page from the U.S. Department of Agriculture (USDA).
2. How many states is it in?
So far, the bird flu has struck 21 states in 298 sites, particularly in the Midwest due to its abundance of commercial farms. Egg-producers in Iowa, the top egg-producing state, have been hit the hardest. Iowa's Gov. Terry Branstad declared a state of emergency on May 1 due to the rising toll of the outbreak. Minnesota and Wisconsin have also declared states of emergency.
3. Where did it come from?
The USDA told TIME that some of the strains currently seen in the U.S. outbreaks originated in Asia, spread via migratory fowl and then mixed with other bird flu strains in North America. What remains a mystery, however, is how the viruses are "getting into large production facilities, where birds are kept indoors under rigorous biosecurity protocols," Mother Jones noted.
Contaminated water or feed is also a suspect, as well as the practice of keeping "tens, or even hundreds, of thousands of animals together in cramped, waste-covered quarters, [who are] fed an unnatural and unhealthy diet, and unable to spend time outdoors or engage in any of their natural behaviors," as Dr. Joseph Mercola pointed out on his popular natural health site.
4. How serious is it?
The USDA told TIME while the high number of birds slaughtered during this outbreak seems very high, it's still "considered a small percentage of the overall U.S. poultry population." According to the agency, in 2014 the U.S. poultry industry produced 8.54 billion broilers, 99.8 billion eggs and 238 million turkeys.
5. If I keep birds, how can I tell if mine are infected?
According to TIME, turkeys and chickens will stop eating or drinking, and appear lethargic (they will die shortly after that). They also might look like they are stargazing or twisting their neck. For egg-laying hens, they may lay fewer eggs. Housebound birds are not particularly at risk for contracting avian flu, but pet owners should not allow them contact with wild birds.
6. Will it increase poultry or egg prices?
No (or at least not yet) for poultry prices, but definitely yes for eggs. According to Harvest Public Media, bakers and restaurants are especially feeling the pinch, as liquid egg prices have shot up 240 percent in some badly affected areas since early May. This means the bird flu could increase the price of anything made with eggs such as baked goods, pasta and other food items. In some grocery stores, the price of a carton of eggs has tripled to up to $3, the publication reported. Some grocery chains in Texas are even rationing eggs. The U.S. has even started importing eggs from The Netherlands to ease shortages.

Dozens of countries have imposed total or partial bans on U.S. poultry and egg imports since the outbreak, including China and South Korea, which accounted for $428.5 million in export sales of U.S. poultry meat and products alone, according to Reuters.
7. What about specialty eggs?
There hasn't been an increase in prices for cage-free and organic eggs because these specialty-egg chicken houses haven't been hit as hard, as egg industry analyst Brian Moscogiuri Urner Barry told the Associated Press.
8. Can I catch the bird flu?
No. There have been no cases of human transmission but the U.S. Centers for Disease Control and Prevention (CDC) recently released an official advisory to warn health workers and clinicians of the potential for human infection. Currently there is no human vaccination for H5 strains but efforts are underway to develop the vaccine in case the need arises.

A fast-spreading variant of the coronavirus that causes COVID-19 has been found in at least 10 states, and people are wondering: How do I protect myself now?
Airborne Particles Are Still the Biggest Problem<p>The <a href="https://theconversation.com/why-it-matters-that-the-coronavirus-is-changing-and-what-this-means-for-vaccine-effectiveness-152383" target="_blank" rel="noopener noreferrer">SARS-CoV-2 variants</a> are believed to spread primarily through the air rather than on surfaces.</p><p>When someone with the coronavirus in their respiratory tract coughs, talks, sings or even just breathes, infectious respiratory droplets can be expelled into the air. These droplets are tiny, predominantly in the range of <a href="https://www.sciencedirect.com/science/article/pii/S0021850211001200?casa_token=KtyrsEfbeqcAAAAA:vv10sSxm33tzg0EQvNMIFtV7GCu5gE9QAzuyzHKr2_4Cl0OFkUJoGwzn4d0ZnEWS19NsOTuH" target="_blank" rel="noopener noreferrer">1-100 micrometers</a>. For comparison, a human hair is about 70 micrometers in diameter.</p><p>The larger droplets fall to the ground quickly, rarely traveling farther than 6 feet from the source. The bigger problem for disease transmission is the tiniest droplets – those less than 10 micrometers in diameter – which can remain suspended in the air as aerosols for <a href="https://academic.oup.com/cid/article/50/5/693/325466" target="_blank">hours at a time</a>.</p>

What Can You Do to Stay Safe?<p>1) Pay attention to the type of face mask you use, and how it fits.</p><p>Most off-the-shelf face coverings are not 100% effective at preventing droplet emission. With the new variant spreading more easily and likely infectious at lower concentrations, it's important to select coverings with materials that are most effective at stopping droplet spread.</p><p>When available, N95 and surgical masks consistently perform the best. Otherwise, face coverings that use <a href="https://www.sciencedirect.com/science/article/pii/S2352431620301802?casa_token=-Dj6nGBAm24AAAAA:qq9BpbzCKaPDFcV73ohA2fCnhE_Zlkss6Bei3kUwq9QYndhHj0Vafbbd-ef_855lx6knDfUt" target="_blank">multiple layers of material</a> are preferable. Ideally, the material should be a tight weave. High thread count cotton sheets are an example. Proper fit is also crucial, as gaps around the nose and mouth can <a href="https://pubs.acs.org/doi/10.1021/acsnano.0c03252" target="_blank" rel="noopener noreferrer">decrease the effectiveness by 50%</a>.</p><p>2) Follow social distancing guidelines.</p><p>While the current social distancing guidelines are not perfect – <a href="https://theconversation.com/what-a-smoky-bar-can-teach-us-about-the-6-foot-rule-during-the-covid-19-pandemic-145517" target="_blank" rel="noopener noreferrer">6 feet isn't always enough</a> – they do offer a useful starting point. Because aerosol concentrations levels and infectivity are highest in the space immediately surrounding anyone with the virus, increasing physical distancing can help reduce risk. Remember that people are infectious <a href="https://medical.mit.edu/faqs/COVID-19#faq-10" target="_blank" rel="noopener noreferrer">before they start showing symptoms</a>, and they many never show symptoms, so don't count on seeing signs of illness.</p><p>3) Think carefully about the environment when entering an enclosed area, both the ventilation and how people interact.</p><p>Limiting the size of gatherings helps reduce the potential for exposure. Controlling indoor environments in other ways can also be a highly effective strategy for reducing risk. This includes <a href="https://theconversation.com/what-a-smoky-bar-can-teach-us-about-the-6-foot-rule-during-the-covid-19-pandemic-145517" target="_blank" rel="noopener noreferrer">increasing ventilation rates</a> to bring in <a href="https://theconversation.com/keeping-indoor-air-clean-can-reduce-the-chance-of-spreading-coronavirus-149512" target="_blank" rel="noopener noreferrer">fresh air and filtering existing air</a> to dilute aerosol concentrations.</p><p>On a personal level, it is helpful to pay attention to the types of interactions that are taking place. For example, many individuals shouting can create a higher risk than one individual speaking. In all cases, it's important to minimize the amount of time spent indoors with others.</p><p>The CDC has warned that B.1.1.7 could <a href="https://www.cdc.gov/mmwr/volumes/70/wr/mm7003e2.htm?s_cid=mm7003e2_w" target="_blank" rel="noopener noreferrer">become the dominant SARS-CoV-2 variant</a> in the U.S. by March. Other fast-spreading variants have also been found in <a href="https://virological.org/t/genomic-characterisation-of-an-emergent-sars-cov-2-lineage-in-manaus-preliminary-findings/586" target="_blank" rel="noopener noreferrer">Brazil</a> and <a href="https://www.who.int/csr/don/31-december-2020-sars-cov2-variants/en/" target="_blank" rel="noopener noreferrer">South Africa</a>. Increased vigilance and complying with health guidelines should continue to be of highest priority.</p>
