West Nile virus in North Macedonia: 43 infections and five deaths according to the Ministry of Health

Context and dynamics of the outbreak

West Nile virus is endemic in several areas of the Mediterranean basin and Eastern Europe, and its circulation is favored by heat waves and the presence of Culex mosquitoes, which serve as the main vectors. Authorities recommend that the population adopt individual protection measures, such as repellents, mosquito nets, and the elimination of standing water.

According to the epidemiological data cited by the ministry, human infection occurs mainly between late summer and early autumn, the period when the density of infected mosquitoes reaches its peak. Most infections are asymptomatic or present with mild flu-like symptoms, but a minority develop encephalitis or meningitis.

The Ministry of Health has activated an integrated surveillance plan involving hospitals, general practitioners, and laboratories, with the aim of early identifying new cases and isolating outbreaks. Information campaigns aimed at citizens have been intensified, especially in rural areas and along waterways, where mosquito proliferation is more marked.

Prevention and surveillance measures

In the Balkan region, the circulation of West Nile virus is being monitored by health authorities in several countries, which share data and intervention protocols. The proximity to other nations already affected by recent outbreaks makes cross-border cooperation a key element of the response.

The ministry recalled that there is currently no specific vaccine available for widespread use against West Nile virus and that prevention is essentially based on vector control and protection against bites. Health facilities have been urged to promptly report all suspected cases of meningoencephalitis.

People at higher risk, particularly the elderly, chronic patients, and fragile individuals, are urged to avoid outdoor evening and nighttime hours in areas with higher mosquito density and to consult a doctor immediately in case of sudden high fever, severe headache, or neck stiffness.

At-risk categories and recommendations

The Ministry of Health assured that the situation is being constantly monitored and that regular updates will be disseminated through official channels. Attention remains high on the possible extension of the outbreak in the coming weeks, coinciding with the persistence of high temperatures.

The relevant institutions have launched targeted disinfestation interventions in the most affected areas, with larvicide and adulticide treatments coordinated with local administrations. The operations are designed to reduce the population of vector mosquitoes without compromising the ecosystem, in line with international health authority guidelines.

Disinfestation interventions and regional cooperation

The scientific community is closely monitoring the evolution of the outbreak in North Macedonia, considered a relevant indicator of the circulation of the virus in Southeast Europe. The data collected in the coming weeks will be essential to assess the extent of the epidemic and plan any further containment measures.

The ministry finally urged the population to maintain cautious behavior and to collaborate with health authorities to limit the spread of the virus. Transparency in communicating data is considered essential to avoid alarmism and to ensure an effective response to the ongoing epidemiological situation.
