A Comprehensive Molecular and Epidemiological Characterization of Influenza Viruses Circulating 2016-2020 in North Macedonia.

Influenza viruses know no boundaries, representing an example of rapid virus evolution combined with pressure exerted by the host's immune system. Seasonal influenza causes 4-50 million symptomatic cases in the EU/EEA each year, with a global death toll reaching 650,000 deaths. That being the case, in 2014 North Macedonia introduced the sentinel surveillance in addition to the existing influenza surveillance in order to obtain more precise data on the burden of disease, circulating viruses and to implement timely preventive measures.

Methods for molecular surveillance of influenza used in Macedonia.

The Aim: To present and compare different Nucleic Acid Testing assays used for laboratory diagnosis of influenza virus infection in our country.

Materials And Methods: Respiratory samples used were nose and throat swabs. The RNA extraction was performed with a QIAamp viral RNA kit.

Laboratory surveillance during pandemic influenza season 2009/2010 in Republic of Macedonia.

Objective: To provide virological and epidemiological information on patients laboratory-tested for influenza A/ H1N1pdm during the pandemic season April 2009/May 2010.

Materials And Methods: Demographic and other data were obtained from the request form arriving with the samples of patients whose symptoms met the clinical definition of influenza A infection. The RNA was tested for the presence of influenza virus using the CDC real-time RT-PCR assay.

Measles outbreak in Macedonia: epidemiological, clinical and laboratory findings and identification of susceptible cohorts.

Objectives: Despite a 92-99% national vaccination coverage since 2000, the former Yugoslav Republic of Macedonia experienced a large measles outbreak between 2010 and 2011. Here we investigate the characteristics of patients hospitalized during this outbreak at the Clinic of Infectious Diseases in Skopje.

Methods: Epidemiological, clinical and laboratory data of 284 measles patients, including 251 from Skopje (43.

The first survey about the antibiotic usage in the Republic of Macedonia.

Development of antibiotic resistance represents a major global and Macedonian public health problem. To assess the opinion and knowledge of the citizens of Macedonia about the usage of antibiotics, voluntary and anonymous survey was realized. A total of 239 persons (age 10-67 years) were interviewed.
