The feared rebound of covid-19 that experts expected after Christmas did not happen, but instead a wave of influenza B emerged that mainly hit children under 15 years old. According to data from the Acute Respiratory Infections Surveillance System (Siriva), the incidence of influenza B in the last week of February was 258 cases per 100,000 inhabitants, above the previous peak of flu in this autumn and winter season, which occurred in the first days this year.

The increase in infections is concentrated mainly in children under 15 years old, explain experts from the Carlos III Institute and the National Epidemiological Surveillance Network, authors of the report. The best news, point out experts, is that rates are showing signs of stabilization, which may indicate that the peak of this wave has already been reached.

The rise in flu infections contrasts with the notable decline in other respiratory illnesses. The incidence of covid-19 in Primary Care dropped last week to 32 cases per 100,000 inhabitants (34 in the previous report); and something similar happened with respiratory syncytial virus, which caused a wave of infections in November. At that time, the incidence reached 153 cases (with a special affect in the age group from zero to four years) while now it is only nine, three less than in the previous week.

Influenza is also the main cause of hospitalization within respiratory diseases. 2.9 per 100,000 infected people end up being admitted, with a special preponderance among those over 79 years old, rates higher than covid (1.02) and syncytial virus (1.2).

In Primary Care, the Spanish Society of General and Family Physicians (SEMG) observes an increase in the number of consultations for influenza B and autonomous communities such as La Rioja recognize a “high” incidence, but which will probably “decrease in the coming weeks ».
