That brought the total to four affected counties, with Montcalm County the first to detect the disease in a dairy herd about two weeks earlier.

Avian flu infects person exposed to sick cows in Texas
Federal and state health officials today reported that a person connected to a dairy farm in Texas has tested positive for H5N1 avian flu, the first known case linked to sick dairy cows and the nation’s second since the virus began circulating in wild bird and poultry in 2022.

Comments closedStudy shows 43% to 58% lower prevalence of long COVID among vaccinated people
A new study based on 4,605 participants in the Michigan COVID-19 Recovery Surveillance Study shows that the prevalence of long COVID symptoms at 30 and 90 days post-infection was 43% to 58% lower among adults who were fully vaccinated before infection.
The study appeared yesterday in the Annals of Epidemiology.
The 30- and 90-day timeframes were meant to compare two different definitions of long COVID. The US Centers for Disease Control and Prevention defines the condition as new or persistent symptoms 4 weeks after infection, while the World Health Organization definition defines it as 12 or more weeks after infection.
