Hospitals across New Zealand have been flooded with babies suffering from respiratory viruses, including a potentially deadly one known as RSV. Experts say the crisis is due to ‘immunity debt’ caused by Covid-19 lockdowns. Doctors have warned that the outbreak is due to children not developing immunity to other viruses suppressed by Covid lockdowns, which has led to a 99.9% reduction in flu cases and a 98% reduction in RSV. However, over the past five weeks, New Zealand has reported 1,000 new RSV cases, according to the Institute of Environmental Science and Research.
The chief medical officer for Wellington explained how people experience near-universal exposure to RSV as children and said most are exposed in their first year of life, but if that exposure is removed for a period the children remain unexposed which leads to a much bigger outbreak when they are eventually exposed to the virus. The longer these periods of viral or bacterial low-exposure, the greater the likelihood of future epidemics. Australia has also experienced a surge, with hospitals in Victoria being overcrowded by unusually high rates of RSV.
Looks like something the UK needs to be aware of in the coming year.
