Influenza, with “immunity debt” we risk the worst wave for 15 years

According to the Federation of General Practitioners (Fimmg) «the flu epidemic curve has risen in such a way as to predict, if the trend remains at these levels, the highest peak in the last 15 years. And it could be reached before Christmas because the values ​​have grown a lot ».

The most sensitive people are the very young, aged 4 years or younger, and the elderly, aged 85 years or older. Fortunately today it does not seem to be particularly aggressive in terms of possible complications and the key symptoms of the 2022-2023 flu are the same as in past seasons: high fever that appears suddenly, at least one respiratory symptom (cough, sore throat, stuffy nose, … ), at least one systemic symptom (feeling of broken bones, muscle aches, headache) .

Symptoms that generally tend to fade within 5-7 days at most (slightly more in children), while asthenia and cough can last much longer. The incubation time, i.e. the period between infection and the first manifestations, varies from one to four days.
