Less flu — more other respiratory infections: Are the islands ready?

Answer

Why are respiratory infections increasing in Mallorca even when flu numbers go down?

A drop in flu cases does not automatically mean overall respiratory illness is falling. In Mallorca, other viruses such as RSV, parainfluenza and rhinoviruses can rise at the same time, especially among children and older adults. Seasonal changes, testing patterns and reporting also affect the numbers, so flu data alone gives only part of the picture.
