A modeling study estimates that COVID-19 vaccination prevented more than 1.5 million infections, 72,000 hospitalizations, and 19,000 deaths in the first 10 months of vaccination in California, according to a study published late last week in JAMA Network Open.
Adults hospitalized early in the pandemic with COVID-19 were at more than triple the risk of death than those with influenza, despite the flu patients being older and having more chronic illnesses, according to new data from Spain to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), which starts tomorrow.
Four states, including hard-hit Minnesota, reported more highly pathogenic avian flu outbreaks, pushing the nation's poultry losses to more than 28.8 million birds from 29 states.
The H5N6 avian flu virus has sickened one more in China, a man from Sichuan province in the country's southwest, Hong Kong's Centre for Health Protection (CHP) said today.
The 56-year-old man's symptoms began on Mar 31, and he was hospitalized on Apr 4 where he is remains in serious condition. An investigation found that he had been exposed to live domestic poultry before he got sick.
In the latest highly pathogenic avian flu developments, the Indiana State Board of Animal Health (BOAH) yesterday said samples from a third duck farm in Elkhart County were positive for avian influenza in preliminary testing.
In an email, the BOAH said the farm houses about 6,500 ducks and is near another quarantined site. It added that the control area extends slightly into Michigan's LaGrange County.
The outbreaks involve the Eurasian H5N1 strain, which has led to the loss of about 26 million US birds.
Rates of upper airway infections (UAIs) such as croup and bacterial tracheitis among pediatric COVID-19 patients, though low, rose after the Omicron variant became dominant in December 2021, with more than one fifth of hospitalized children with both conditions developing severe illness, estimates a study today in JAMA Pediatrics.
In its first evaluation of COVID-19 exposures among US healthcare professionals (HCPs) over the first year of the pandemic, the Centers for Disease Control and Prevention (CDC) reports that most HCPs were likely infected at work rather than in the community.
Two new studies describe benefits of the monoclonal antibody (mAb) treatment casirivimab-imdevimab in adult COVID-19 outpatients, both suggesting lower rates of hospitalization, intensive care unit (ICU) admission, and death in an era dominated by the Delta variant.
Approximately 2.4 out of every 1,000 patients hospitalized with COVID-19 developed myocarditis, an inflammation of the heart muscle that typically follows viral infections, according to an international study published yesterday in the American Heart Association (AHA) journal Circulation.
When including possible myocarditis cases, the rate increases to 4.1 per 1,000 hospitalized patients.
