During the 45th week of 2019 (from 04.11.2019 – 10.11.2019), 39 (I = 1.9/ 100,000) cases of influenza / flu-like illnesses were reported in the Republic of North Macedonia.
Compared to the number of cases registered in the 45th week of last season , and compared to the typical seasonal curve (n = 64), the number of reported cases was 2 times lower. (n=78) (Chart 1).
The reported incidence is below the weekly limit of seasonal activity of the influenza virus (I = 36.38 / 100,000). Influenza activity is below the seasonal level, ie the threshold for entry into the influenza season has not yet been reached (chart 1).

Regarding the distribution of the diseases by age groups, the highest number of cases (n = 22; 56.4%) was reported in the age group that covers the largest part of the population (15-64 years) –and the highest incidence (4.3 / 100,000) is registered in children aged 0-4.
This week, 6 reported units reported cases. Most of the cases were reported from Gostivar (n = 14) and Kumanovo (n = 10). The highest weekly incidence (I = 11.7 / 100,000) is registered in Gostivar.

According to a report by Flu News Europe released in week 44 of 2019, influenza virus activity is at a low seasonal level across the European region. Influenza viruses are sporadically detected in patients with respiratory disease, and Influenza A and Influenza B. isolates are being isolated. From sentinel surveillance 3.1% of tested positive are influenza viruses:
49 Influenza A
A(H1N1)pdm09 – 19
A(H3N2) – 29
A non subtyped -1
33 Inluenza B
Victoria lineage – 11
- Underemined line subtype (A)-22
