Fourth human case of bird flu connected to dairy cattle outbreak identified in the US

30 YEARS AGO, A BOSTON COMPANY WILL GET $170 MILLION TO DEVELOP TO DEVELOP A BIRD FLU VACCINE. MODERNA SAYS IT WILL USE THE SAME MRNA TECHNOLOGY USED TO PRODUCE SHOTS FOR COVID 19. HERE TO TALK ABOUT THIS, DOCTOR SHIRA DORON, THE CHIEF INFECTION CONTROL OFFICER FOR TUFTS MEDICINE HEALTH SYSTEM, WHICH IS WHY YOU’RE THE PERSON TO ASK THIS OF HEALTH OFFICIALS ARE TRYING TO CONTAIN THIS OUTBREAK. DOCTOR, A BIRD FLU THAT’S ALREADY INFECTED AT LEAST 130 HERDS OF DAIRY COWS IN 12 STATES. WHAT CAN YOU TELL US ABOUT THE NUMBER OF HUMAN CASES YOU KNOW, WE THINK THAT DAIRY COW INFECTIONS MAY HAVE BEEN GOING ON LONGER THAN WE REALIZED AS FAR BACK AS DECEMBER OR JANUARY, AND YET, THANKFULLY, THERE HAVE BEEN ONLY THREE REPORTED HUMAN INFECTIONS ASSOCIATED WITH THE VIRUS. ALL THREE HAD MILD INFECTION. ALL OF THEM HAD CLOSE CONTACT WITH COWS, AND NONE TRANSMITTED IT TO OTHER HUMANS, INCLUDING THE PEOPLE IN THEIR HOUSEHOLD. NOW WE’RE PROBABLY MISSING SOME OTHER MILD HUMAN CASES, BUT STILL, THOSE STATISTICS ARE PRETTY REASSURING. THEY ARE SO IT SOUNDS LIKE THE INFECTION RISK AMONG PEOPLE IS LOW. WHY IS THE GOVERNMENT SPENDING MILLIONS NOW TO DEVELOP THIS VACCINE? YOU KNOW, COVID TAUGHT THE WORLD THAT VIRUSES, GENETIC CODE MUTATES AND FLU IS A NOTORIOUS MUTATOR. THE RISK TO PEOPLE WHO DO NOT WORK WITH CATTLE AND POULTRY IS LOW TODAY, BUT MUTATIONS IN THE VIRUS’S GENETIC CODE COULD MAKE IT BETTER SUITED TO INFECT PEOPLE TO SPREAD BETWEEN PEOPLE, OR COULD EVEN MAKE IT MORE LETHAL TO PEOPLE. AND THOSE CHANGES WOULD GIVE IT PANDEMIC POTENTIAL THAT IT DOES NOT HAVE TODAY. AND FOR ALL THOSE REASONS, WE NEED TO BE PREPARED WITH VACCINES AND TREATMENTS. SO ARE YOU TRYING TO GET AHEAD OF IT? YEAH. SO WHILE THIS OUTBREAK CONTINUES, SHOULD PEOPLE AVOID CONTACT WITH FARMS AND BIRD FEEDERS JUST TO BE SAFE? WHAT’S YOUR ADVICE? THE MOST IMPORTANT ADVICE FOR THE GENERAL PUBLIC AROUND THIS IS ONE STAY AWAY FROM RAW, UNPASTEURIZED MILK. PASTEURIZATION DOES MAKE THE MILK FROM INFECTED COWS SAFE. AVOID HANDLING SICK OR DEAD ANIMALS IN THE WILD. IF YOU HAVE TO WEAR GLOVES, WASH YOUR HANDS VERY WELL. AFTERWARD. PEOPLE WITH BACKYARD BIRD FEEDERS OR CHICKENS SHOULD PAY SPECIAL ATTENTION TO HANDWASHING AS WELL. FARM WORKERS SHOULD USE PERSONAL PROTECTIVE EQUIPMENT WHEN THEY’RE HANDLING OR DEALING WITH ANY ANIMALS KNOWN TO BE PART OF THIS OUTBREAK, LIKE COWS, CHICKENS AND ALPACA. GREAT ADVICE, DOCTOR DORON, AL

A fourth farm worker has been infected with bird flu in the growing outbreak linked to dairy cows, health officials reported Wednesday.The worker had direct contact with infected dairy cows on a northeast Colorado farm, state and federal health officials said. The man developed pink eye, or conjunctivitis, received antiviral treatment and has recovered.Three previous cases of human infection linked to cows have been reported in dairy workers in Texas and Michigan since March. Two of those workers also developed pink eye, while one had mild respiratory symptoms, In 2022, the first U.S. case of bird flu was detected in a Colorado farm worker exposed to infected poultry.The Centers for Disease Control and Prevention said the new infection “does not change” the agency’s assessment that the risk to the general public remains low. Surveillance systems tracking flu in the U.S. have shown no unusual activity, officials said. However, people with prolonged contact with to infected birds or other animals, including livestock, or to their environments, are at higher risk of infection.The Colorado man was being monitored when he developed symptoms because of his work with dairy cows, according to the CDC. Tests at the state level were inconclusive, but samples sent to CDC tested positive. Full results of genetic analysis of the sample are pending.As of Wednesday, more than 135 dairy herds in a dozen states had reported infections with the H5N1 virus that originated in poultry, according to the Agriculture Department.
