H5 #birdflu viruses have occasionally infected mammals that eat H5 virus-infected birds or poultry. Recent US reports of H5 #birdflu viruses detected in some mammals are not surprising given the widespread outbreaks of H5 bird flu in wild birds. More:
Reports of H5 #birdflu viruses in some mammals are not surprising given widespread outbreaks in wild birds. Risk to the general public is low, but ppl who get sick after contact w/potentially infected sick or dead animals should call their health dept:
This week, @CDCDirector adopted the Advisory Committee on Immunization Practices’ recommendation to preferentially recommend the use of specific flu vaccines for adults 65 years and older, including higher dose and adjuvanted flu vaccines. Learn more:
#DYK that #flu viruses change constantly? Small changes in the genes of #flu viruses happen continually. These gradual changes are called “antigenic drift.” More abrupt, major changes can also happen, this is called “antigenic shift.” Learn more:
One pediatric flu death was reported in this week’s #FluView report, bringing the total for the 2021-2022 flu season to 30. In past seasons, about 80% of flu deaths in children occurred in children who were not fully vaccinated against flu. Learn more:
US reports of H5 #birdflu virus infections in some mammals don't change the risk for the public, which CDC considers to be low. Ppl should avoid wild birds & animals that appear sick or dead, & keep their pets away from sick or dead birds & animals.
Evidence suggests higher dose and adjuvanted flu vaccines are potentially more effective against flu and its serious complications than standard-dose flu vaccines among people in this age group. Learn more:…
