West Nile fever escalates in Balkans and California

Overview

The West Nile fever epidemic in North Macedonia has expanded, with health authorities reporting 43 total cases, including 40 confirmed infections. Four deaths have been recorded, primarily among elderly citizens in the Skopje region. Officials have identified 34 high-risk areas, including locations with stagnant water and organic waste, and have implemented mosquito control measures such as fumigation and SMS alerts.

Health Minister Sasho Klekovski has identified septic tanks, stagnant water, and dead river sections as significant risks for virus spread. He recommended the disinfection of septic tanks as a protective measure, particularly for suburban areas around Skopje that lack urban sewage systems. However, the specific bacillus tablets required for such disinfection are currently unavailable in the country, a resource that is already being utilized in Greece. Other identified breeding grounds include irrigation channels in the Skopje Field, sand pits, cemeteries, and old tire deposits.

In Skopje, 13 zones have been designated as high priority for mosquito spraying, using preparations verified as safe by World Health Organization recommendations. This follows previous political disputes in the capital regarding the timing and efficacy of municipal disinfection efforts.

Regionally, Greece has reported 157 domestic cases and 13 deaths as of August 19, 2026, with fatalities occurring exclusively in patients over age 65. In the United States, California is seeing a five-year high in activity, with 30 human cases and three fatalities reported as of mid-August.
