Nevada Resident Infected with New Strain of Bird Flu: 'We're Gonna Have Another Influenza Pandemic'
The Centers for Disease Control and Prevention (CDC) has confirmed that a Nevada resident has been infected with a new strain of the bird flu.
On Feb. 10, the Central Nevada Health District (CNHD) reported a case of the bird flu (highly pathogenic avian influenza, HPAI) in a worker who had exposure to infected dairy cattle at a farm in Churchill County.
Health officials said the dairy worker's illness was mild, they were not hospitalized and have since recovered.
The patient reportedly had the D1.1 strain of bird flu, differing from the B3.13, which is the strain of the virus that has resulted in the majority of human infections in the United States. This new strain was first confirmed in Nevada cattle on Jan. 31 after the virus was detected in milk collected for monitoring purposes in December.
The latest development raises concerns about whether dairy cows may be more susceptible to the bird flu, which would increase the risk of cow-to-human transmission.
'Some experts do fear that it could mark a new chapter in the outbreak or that bird flu may become endemic in the U.S.,' Andrea Garcia — vice president of science, medicine and public health at the American Medical Association — said during a news brief on Feb. 10. 'This is something we are continuing to very closely follow.'

'That's a big deal,' Michael Osterholm — infectious disease expert and director of the Center for Infectious Disease Research and Policy at the University of Minnesota — told NBC of the virus being found in more cows.
'We're gonna have another influenza pandemic, and when it happens, we shouldn't be surprised,' he added.
However, the CDC and CNHD said the public health risk for the general public remains low, while noting that 'people who work with birds, poultry or cows, or have recreational exposure to them, are at higher risk.'
Those at greater risk are encouraged to avoid touching sick or dead animals, and ensure that they are not eating uncooked or undercooked food. Cooking poultry and eggs to an internal temperature of 165˚F kills bacteria and viruses, according to the CDC.
Last Month, health officials announced the first death in the United States linked to the bird flu. The Louisiana Department of Health confirmed on Jan. 6 that a 65-year-old man died from the virus after exposure to 'a combination of a non-commercial backyard flock and wild birds.'
The World Health Organization previously called the current outbreak a 'significant public health concern.' However, the agency does not currently list the bird flu outbreak as a global health emergency.

What to know about rare brain-eating amoeba after Texas woman dies
A Texas woman has died from a rare brain-eating amoeba after using a sinus rinse with contaminated water, according to a case report from the Centers for Disease Control and Prevention. The 71-year-old woman -- who was previously healthy -- used tap water at a campground in a nasal irrigation device, and health officials believe this is how she contracted the amoeba, the report states. She developed a brain infection known as primary amebic meningoencephalitis (PAM) and died eight days after symptoms began, according to the report. Other details about the patient including name, race/ethnicity or town of residence were not provided in the report. Here's what to know about the rare, but often fatal, disease. Naegleria fowleri (N. fowleri) is an amoeba, which is an organism so small it can only be seen with a microscope. It lives in soil and freshwater ponds, lakes, rivers and hot springs, according to the CDC. It is rarely found in swimming pools, splash pads and tap water. Most infections with N. fowleri occur when people swim in contaminated water and submerge their heads, causing the amoeba to enter the nose. People cannot be infected if they swallow contaminated water, and they cannot spread the amoeba to others, the federal health agency said. N. fowleri is known as a " brain-eating amoeba" because it can infect the brain, causing a disease known as PAM, according to the CDC. PAM also can occur when people use contaminated tap water to "cleanse their noses during religious practices" or "irrigate their sinuses," the latter of which occurred with the Texas woman in the CDC case report. Symptoms typically begin five days after exposure but can occur anywhere from one to 12 days after infection, according to the CDC. Early symptoms resemble those of bacterial meningitis and can include headache, nausea, vomiting and fever. PAM can progress to more severe symptoms such as neck stiffness, seizures, hallucinations, altered mental state and coma. The disease progresses quickly because a diagnosis is hard to confirm. PAM is almost always fatal, occurring in 97% of cases and, on average, five days after symptoms begin. If PAM is caught early enough, it can be treated with a combination of drugs including antifungal medications, and sometimes antibiotics, the CDC said. Fewer than 10 people in the U.S. every year develop PAM, according to the CDC. Between 1962 and 2023, there have been 164 reported cases of PAM in the U.S. with just four survivors, the federal health agency said.

Salmonella outbreak tied to recalled eggs makes dozens sick across 7 states in the West and Midwest
A salmonella outbreak linked to a large egg recall has made dozens of people sick in seven states in the West and Midwest, federal health officials said Saturday. The August Egg Company recalled about 1.7 million brown organic and brown cage-free egg varieties distributed to grocery stores between February and May because of the potential for salmonella, according to an announcement posted Friday on the Food and Drug Administration's website. At least 79 people in seven states have gotten a strain of salmonella that was linked to the eggs, and 21 people have been hospitalized, the Centers for Disease Control and Prevention said. The recall affects retailers in Arizona, California, Illinois, Indiana, Nebraska, New Mexico, Nevada, Washington and Wyoming. The recalled eggs were sold under brand names including Clover, First Street, Nulaid, O Organics, Marketside, Raleys, Simple Truth, Sun Harvest, and Sunnyside. Plant code numbers for the recalled eggs are P-6562 or CA5330, according to the CDC's website. This Centers for Disease Control and Prevention map shows the locations of people affected by a Salmonella outbreak linked to eggs. Centers for Disease Control and Prevention "August Egg Company's internal food safety team also is conducting its own stringent review to identify what measures can be established to prevent this situation from recurring," the company said in a statement on the FDA's website. "We are committed to addressing this matter fully and to implementing all necessary corrective actions to ensure this does not happen again." Symptoms of salmonella poisoning include diarrhea, fever, severe vomiting, dehydration and stomach cramps. Most people who get sick recover within a week. Infections can be severe in young children, older adults and people with weakened immune systems, who may require hospitalization. The CDC advises people to throw away recalled eggs or return them to the store where they were purchased. Consumers should also wash and disinfect any surfaces that came in contact with the eggs. This is the latest in a string of salmonella-related outbreaks recently involving food. A tomato recall affecting three southern states was upgraded to a Class I recall, the most severe warning by the Food and Drug Administration. The recall was first announced in May over potential salmonella contamination. Also, nearly four dozen people across 18 states have gotten sick with salmonella food poisoning tied to recalled cucumbers, according to federal health officials. In an update, the CDC said the expanding outbreak led to at least 16 people being hospitalized.
