“RSV is the most common cause of bronchiolitis and pneumonia in children under one year of age in the United States. Infants, young children, and older adults with chronic medical conditions are at risk of severe disease from RSV infection,” ha detto il CDC.
“Each year in the United States, RSV leads to on average approximately 58,000 hospitalizations with 100-500 deaths among children younger than 5 years old and 177,000 hospitalizations with 14,000 deaths among adults aged 65 years or older.”
RSV is one of the viruses seen more commonly in fall and winter, but incidence plummeted during the pandemic.
“tuttavia, since late March, CDC has observed an increase in RSV detections reported to the National Respiratory and Enteric Virus Surveillance System (NREVSS), a nationwide passive, laboratory-based surveillance network,” ha detto il CDC.
Spread has been seen in Alabama, Florida, Georgia, Kentucky, Mississippi, Carolina del Nord, Carolina del Sud, Tennessee, Arkansas, Louisiana, Nuovo Messico, Oklahoma and Texas.
“Due to reduced circulation of RSV during the winter months of 2020–2021, older infants and toddlers might now be at increased risk of severe RSV-associated illness since they have likely not had typical levels of exposure to RSV during the past 15 mesi,” ha detto il CDC.
There’s no specific treatment for the virus.
