Global risk remains low, but health surveillance is intensifying in some countries

The outbreak in the Atlantic Ocean has taken on international proportions. Authorities are tracking exposed people in at least twelve countries, including the UK, the US, Germany and France.

In Singapore, two passengers are being monitored, with one of them showing suspicious symptoms. The WHO reports a total of eight cases, of which five are confirmed and three have resulted in death.

Although the risk to the population remains low, the long incubation period means that the number of cases may change. Andes hantavirus infection is insidious because the initial stage resembles the flu: fever, muscle aches, headaches and gastrointestinal disturbances.

In the most severe forms, the condition rapidly deteriorates into pulmonary syndrome, causing breathing difficulties and the need for intensive therapy. Mortality in severe cases reaches up to forty percent.

Early diagnosis is difficult because the symptoms overlap with those of Covid-19, pneumonia or dengue. Confirmation is done only through the laboratory, using serological tests or molecular techniques to detect viral RNA in the blood.

There is currently no specific cure or vaccine for hantavirus. Treatment is based on clinical support of vital functions. Prevention requires limiting contact with rodents, as the virus is transmitted through their urine, saliva, or feces.

Main measures include hand hygiene, case isolation, and closing rodent entrances to buildings. Comparison with Covid-19 is inevitable, but the epidemiological differences are profound.

Hantavirus is a zoonosis (from animal to human) and human transmission has only been documented for the Andes type in cases of very close contact. Unlike Sars-CoV-2, hantavirus has not shown the ability to spread massively and sustainably in the population.

Current tracing focuses on identifiable contact chains rather than general community circulation. For this reason, we are not facing a pandemic dynamic similar to that of 2020.

How worried should we be? The answer is clear: the individual risk remains low. The increased international attention comes from the fact that this is an international cluster with passengers who moved across continents before the outbreak was known.

In the coming weeks, epidemiologists will determine whether the infections occurred from the shared environment or through secondary transmission between people.

This technical distinction will be crucial to the scientific understanding of the event. The message from the authorities remains unchanged: high surveillance and clinical care, but without a generalized alarm. tessheshi
