Sick California Farmworkers Could Help Reveal Evolution Of Bird Flu
Federal scientists are closely studying H5N1 genetic sequences from California dairy workers in search of any dangerous mutations that may make the virus, called avian flu or bird flu, more skilled at jumping from animals to people — then spreading. “It can tell us how the virus is evolving,” said Stanford infectious disease expert Dr. Abraar Karan. “It is a window into what is going on.” (Krieger, 10/5)

Is Bird Flu Spreading In People? Without Blood Test Results, Officials Can't Say
A total of seven people who were in close contact with a bird flu patient in Missouri developed symptoms, the Centers for Disease Control and Prevention said Friday, but it remains unclear whether these represent cases of human-to-human spread of the virus. Antibody blood test results, which will come back later this month, officials said, are needed to answer that question. Since most of the seven people weren’t tested for bird flu, it’s not yet known whether any of them were infected with the virus or another pathogen. (Lovelace Jr., 10/4)

Sanofi, GSK, CSL Tapped To Expand US Bird Flu Vaccine Supply
GSK, Sanofi, and CSL Ltd have secured $72 million from the U.S. government to ramp up production of bird flu vaccines, a health official said on Friday during a press briefing. The move comes as a multi-state outbreak among livestock and poultry has caused human illnesses and infected more than 254 herds in 14 states since March, according to government data. The companies will use the funds to fill vials and pre-filled syringes so that doses can be ready to distribute if needed, said David Boucher, director of Infectious Disease Preparedness and Response for the U.S. Department of Health and Human Services.

Highly Aggressive, Dangerous Mosquito Species Found Again In Santa Clara County
Discovery of more dangerous and highly aggressive Aedes aegypti mosquitos near a San Jose cemetery has Santa Clara County officials imploring residents to remove standing water and give access to pest-control crews so the insects don’t becoming a permanent menace. The invasive mosquitos can transmit dengue, yellow fever and other serious diseases, and also threaten “our way of life” because of their voracious feeding on human blood can take place in the middle of the day, unlike the state’s native mosquitos, the county warned in a Friday press release.
