During the 9th week of 2025 (24.02.-02.03.2025), 3 904 cases of acute respiratory diseases and influenza were recorded among a surveillance population of 346 739 people, representing an incidence rate of 112.59 per 10 000 population. The national incidence rate decreased compared to the previous week (4 144 cases of acute respiratory diseases and influenza in a surveillance population of 346 739 persons, incidence rate 119.51 per 10 000 population). Overall morbidity decreased compared to the previous week, particularly marked in young children. The incidence by age group was: 423.97 per 10 000 in 0-4 years; 331.34 per 10 000 in 5-14 years.

In the Influenza and ARI NRL, 57 clinical samples of ARI patients were simultaneously tested for influenza A/B and SARS-CoV-2 viruses by Real Time PCR. 9 A(H1N1)pdm09 influenza viruses, 13 A(H3N2)influenza viruses, 54 influenza B/Victoria viruses were detected.
RSV (in 16 samples), adenovirus (in 4 samples), and other respiratory viruses in 7 samples were demonstrated in 161 clinical samples of children under 5 years of age additionally tested for non-influenza respiratory viruses.
Combinations of respiratory viruses were evidenced in single cases of the tested samples, i.e., the patients had mixed infections.
