Influenza activity in England and Wales: October 1998 to June 1999

Influenza activity in England and Wales in the winter of 1998/1999 reached the highest weekly levels seen since the epidemic of 1989/1990. Activity peaked at Christmas and the New Year, adding to the winter pressures on general practitioner and hospital services. Adults aged 65 years and over consulted with general practitioners at the highest rates. Outbreaks of influenza or flu-like illness occurred in several schools and nursing homes and, in June 1999, on a British cruise ship in the Mediterranean. Deaths from all causes reached a higher peak in week 1 of 1999 than occurred in the peak week of the influenza epidemic of 1989/90.
