Twelve new cases have been reported in the past 2 days in an outbreak of acute hepatitis A linked to an organic frozen berry mix, bringing the total to 99, the US Centers for Disease Control and Prevention (CDC) said today.
A study from a Wisconsin team indicates that influenza vaccination does not increase the risk of infection with other respiratory viruses, which supports the validity of a common method for assessing flu vaccine effectiveness (VE) in observational studies.
A hepatitis A outbreak linked to a frozen berry mix has grown to 49 cases, 11 hospitalizations, and 7 states, the US Centers for Disease Control and Prevention (CDC) said in an update today. Those figures have grown by 19 cases, 2 hospitalizations, and 2 states (Hawaii and Utah) since the agency's last update on May 30.
