The peak of influenza will arrive in mid-January, and the incidence rate has risen to 25%

Covid-19 hospitalization rate: 2.3 per 100,000 inhabitants (previous week: 1.9)

The highest incidence of acute respiratory infections (ARIs) in primary care is among children under one year old (4,442 cases/100,000 hours)

Seasonal influenza is a highly contagious disease caused by influenza viruses. In humans, it causes acute respiratory infections, which can progress from mild infection to severe and sometimes fatal disease. We must keep an eye on its evolution, and vaccines will be crucial for vulnerable groups or those over 60 years of age. The emergency situation in Spain at the end of the year is particularly complex due to the rising incidence of coronavirus and influenza.

But what do the data so far say? The incidence rate of acute respiratory diseases in primary care in Spain is 908.6 cases per 100,000 inhabitants, an increase of 12.7% from 806 cases per 100,000 inhabitants in the previous week, especially influenza cases, according to a report by the Carlos III Health Institute (ISCIII). Its positivity rate has risen to 25%, while the Covid-19 positivity rate has risen to 13% in the last week.

weekly report Sentinel surveillance of acute respiratory infections in primary care (ARI) and hospitals (SARI): influenza, COVID-19, and RSV The latest version of ISCIII compiles data for the week of December 18 to 24. It is worth noting that these latest figures show an increase in respiratory infection cases in recent weeks, with these rates per 100,000 people since two weeks ago. 532 cases and the number of residents is now 908. However, last week’s report showed a 37% increase in respiratory infections, compared with a 12.7% increase this week. While all infections (influenza, Covid-19 and RSV) are increasing, the incidence of influenza syndrome has increased most significantly.

Likewise, 98.5% of identified influenza viruses are type A.

at the rate of primary health care Since the flu is located in 225.7 cases per 100,000 inhabitants (previous week: 165.7 cases), the Covid-19 incidence rate is 123.4 cases per 100,000 inhabitants (previous week: 101.5 cases).
