Kazakhstan Assesses Risk of Hantavirus Spread After Cruise Ship Outbreak

Kazakhstan’s public health authorities say the risk of imported hantavirus infections remains due to international travel but insist the country’s epidemiological surveillance system is prepared to detect and respond to potential cases. The statement followed an outbreak of hantavirus aboard the cruise ship MV Hondius, which was traveling from Argentina to Cape Verde. According to media reports, three people died and eight confirmed infections were recorded among the ship’s 150 passengers. Kazakhstan’s National Center for Public Health said the Andes orthohantavirus (ANDV) strain responsible for the outbreak is not circulating in Kazakhstan. “Hantavirus infections remain under constant epidemiological control. Kazakhstan has a functioning sanitary and epidemiological surveillance system, infectious threats are continuously monitored, and laboratory facilities and specialists are prepared to diagnose and respond to possible imported cases,” the center said in a statement. Officials added that the current situation remains under control and there are no grounds for public concern at this stage. Health authorities advised citizens to consider the epidemiological situation when traveling abroad, including by consulting the Saqbol health risk map. Residents were also urged to avoid contact with wild rodents, refrain from touching dead animals without protective equipment, ventilate enclosed spaces, and follow basic hygiene rules. The center noted that hantaviruses belong to a group of zoonotic infections carried primarily by rodents. Infection usually occurs through inhalation of air contaminated with particles from the urine, saliva, or droppings of infected animals. Special attention is being paid to the Andes orthohantavirus strain, which differs from most other hantaviruses in its ability to spread from person to person through close and prolonged contact. “This feature makes it epidemiologically significant,” the center said. The incubation period can range from one week to more than a month. Symptoms include fever, headache, muscle weakness, nausea, vomiting, diarrhea, cough, and shortness of breath. In severe cases, the virus can rapidly damage the lungs, leading to respiratory failure and shock. According to health officials, the fatality rate for Andes virus infections can reach 30–40%. The Times of Central Asia previously reported that Kazakhstan declined to introduce quarantine restrictions in response to detected cases of metapneumovirus.
