The city of Zagreb went on an emergency mosquito control mission this morning.

The city of Zagreb has initiated urgent measures to control mosquitoes after seven confirmed cases of West Nile virus infection were reported in Croatia. The virus is transmitted by infected mosquitoes, and the city has begun spraying operations in several neighborhoods on September 1 and 2. Residents are advised to stay indoors during these operations and close windows and doors. Beekeepers are warned to cover their hives due to the sensitivity of bees to insecticides. The spraying will take place in areas such as Savica, Središće, Zapruđe, Travnica, Utrina, Sloboština, and parts of Lower and Upper Zagreb. Two individuals are currently on ventilators, and the virus has been confirmed in dead crows across Zagreb. The first case was recorded in Kopřivnice-Križevci County on August 22. Four of the seven infected people are being treated at the Dr. Fran Mihaljević Infectious Diseases Clinic, while two elderly patients are experiencing severe symptoms requiring respiratory support. Across Europe, there have been 877 reported infections. The head of the Andrija Štampar Institute for Public Health has stated there is no reason for panic, and educational materials have been distributed to

Health authorities in Zagreb have confirmed the presence of the West Nile virus following the discovery of five dead crows infected with the pathogen across different parts of the city. Four human cases are currently under treatment at the Dr. Fran Mihaljević Clinic for Infectious Diseases, with two patients receiving intensive care. The findings indicate heightened viral activity within the urban area, prompting increased mosquito control measures and public health alerts. The initial detection occurred in the neighborhood of Zapruđe, followed by positive tests from four additional locations: Kvaternik Square, Bartol Kašić Park, Savica, and Dubrava. These findings confirm that the virus is circulating through Zagreb's ecosystem, primarily transmitted via mosquitoes that bite infected birds and subsequently transfer the disease to other animals or humans. According to Vladimir Savić, head of the virology and pathology laboratories at the Croatian Veterinary Institute, the spread of the virus among multiple locations suggests a significant presence of the pathogen in the region. West Nile virus typically affects birds, particularly crows, which serve as key indicators of its presence. However, the virus can also infect mammals, including humans, through mosquito bites. While many infections result in mild symptoms or none at all, severe cases involving neurological complications such as confusion, tremors, convulsions, and seizures can occur. According to Ivan Puljiz, director of the clinic treating the affected individuals, mortality rates for these severe cases can reach up to 90 percent, especially among older adults, individuals with pre-existing conditions, or those with weakened immune systems. In response to the outbreak, local authorities have announced intensified mosquito control efforts. Cold fog treatments will begin on Tuesday and Wednesday morning, initially targeting areas such as Savica, the city center, Zapruđe, Travnjak, Utina, and Sloboština. The operation will later expand to cover broader sections of Lower and Upper Zagreb. This measure aims to reduce the risk of further transmission by targeting the mosquito population responsible for spreading the virus. Experts warn that the impact of the virus extends beyond human health. Boleslaw Slocinski, leader of the Aviator project under the BIOM association, highlights that the decline in crow populations could disrupt the ecological balance. With fewer crows, species such as hawks and eagles, natural predators of smaller rodents, may face challenges, potentially leading to an increase in rodent populations, which pose their own risks to public health and urban environments. Authorities urge citizens to report any found dead birds to veterinary services or the Ministry of Agriculture. Personal protective measures, such as avoiding mosquito bites, remain crucial in preventing infection. Public awareness campaigns emphasize the importance of vigilance and prompt reporting to help contain the spread of the virus and mitigate its effects on both human and animal populations.

Instructions to citizens: How to act and who to contact if you see a dead crow

U Hrvatskoj je potvrđeno sedam slučajeva zaraze virusom Zapadnog Nila, od kojih pet na području Zagreba i Zagrebačke županije. Virus je prvi put potvrđen kod uginulih vrana u Zagrebu, a uključuje lokacije poput Kvaternikovog trga i Parka Bartola Kašića. Četvero oboljelih liječi se u Klinici za infektivne bolesti 'Dr. Fran Mihaljević', a dvoje je na intenzivnoj njezi. Pojava virusa ponovno podiže pitanje brojnosti vrana u gradu i mogućeg utjecaja gospodarenja otpadom na njihovu populaciju. Vrane mogu biti rezervoari virusa koji se prenosi putem komaraca. Građani su upozoreni da ne diraju uginule ptice i da prijeđu informacije o njima nadležnim službama.

West Nile virus spreads in Zagreb: Two out of four patients are in intensive care

The article reports on the spread of the West Nile virus in Zagreb, Croatia, highlighting the confirmation of the virus in five dead pigeons across different locations in the city. Four patients are currently being treated at the Infectious Diseases Clinic in Zagreb, two of whom are on intensive care. Experts from the Veterinary Institute of Croatia and the Interreg Aviator project note that the virus circulates among birds through mosquitoes, which can then transmit it to humans and other mammals. The virus has been detected in areas such as Zapruđa, Kvaternikov Square, Bartola Kašić Park, Savica, and Dubrava. Authorities are intensifying mosquito control efforts in these areas, starting early Tuesday and Wednesday during cold fog conditions. The experts warn that the virus could disrupt the urban ecosystem by affecting bird populations and potentially leading to an increase in unwanted species like rats and mice.

Why objectivity (75): There is a slight shift towards emphasizing the need for action, particularly through the mention of urgent measures by the 'Štampar' institute. This could be seen as a minor editorial tilt toward urgency rather than neutrality.
