Respiratory syncytial virus kills 100,000 under-fives every year
Respiratory syncytial virus is killing 100,000 children under the age of five every year worldwide, new figures reveal as experts say the global easing of coronavirus restrictions is causing a surge in cases.
RSV is the most common cause of acute lower respiratory infection in young children. It spreads easily via coughing and sneezing. There is no vaccine or specific treatment.
RSV-attributable acute lower respiratory infections led to more than 100,000 deaths of children under five in 2019, according to figures published in the Lancet. Of those, more than 45,000 were under six months old, the first-of-its-kind study found.
More children are likely to be affected by RSV in the future, experts believe, because masks and lockdowns have robbed children of natural immunity against a range of common viruses, including RSV.
“RSV is the predominant cause of acute lower respiratory infection in young children and our updated estimates reveal that children six months and younger are particularly vulnerable, especially with cases surging as Covid-19 restrictions are easing around the world,” said the study’s co-author, Harish Nair of the University of Edinburgh. “The majority of the young children born in the last two years have never been exposed to RSV (and therefore have no immunity against this virus).”
