It is a viral strain different from that of Patagonia, which is not contagious through contact with other people. This year, no cases were reported in the province, but in Entre Ríos, in the rural area of the Gualeguay department.

In Santa Fe, it is common that every year there are a dozen cases of hantavirus. Last year, for example, 15 affected patients were confirmed, 2 of whom died, and 10 cases were detected in 2017, according to the Provincial Ministry of Health statistics.
Dr. Carolina Cudós, director of Santa Fe Epidemiology, explained to El Litoral that it is a viral strain different from the one that caused the 28 positive cases in Epuyén (Chubut), with ten confirmed deaths. In the Santa Fe region, the most common variety of hanta is called Lechiguana – or the strain of the central area – and Patagonia is called the Southern Anze.
The virus of this virus is rodents like the long-tailed mouse, but in the case of the strain in the south of the country, the problem is that it is also apparently infected by contact between humans and not only by the breathing of urine particles and infected feces leaving the mice.
The San Miguel Health Promotion and Prevention Division has explained that people can become infected when they come in contact with saliva, faeces and rodent urine (when they breathe the particles when they measure a house because they exist, for example, rodents). In addition, it can be through direct contact when you touch live or dead rodents infected or by biting them.
Symptoms start as a flu with fever, great degradation, muscle pain and catarrh. Then, you can see lowering blood pressure, sudden tachycardia and rising temperature. In some cases, it usually produces gastroenteritis with vomiting, usually accompanied by diarrhea, reported from the health portfolios.
After a few days, there may be a respiratory suffering that would be aggravated, producing what is called the Hantavirus Cardiopulmonary Syndrome, which, although rare, can lead to death if it is not treated in time.
There is no specific treatment against the disease. Those patients with cardiopulmonary syndrome due to hantavirus should be assisted in hospitals, preferably with intensive care units that have mechanical ventilation.

With half the province affected by floods, the Ministry of Health projects an increase in the number of leptospiroses, another disease transmitted by transmitters. To prevent them, antibiotics against this bacteria are distributed to people living in flooded areas in the north of the province. There is already a serious patient for this disease at Cullen Hospital.
Those who traveled to the south
If a person has traveled to the outbreak area in Patagonia and has any of these symptoms, they should consult their doctor and ask for information at the Provincial Bureau of Health Promotion and Prevention in Bv. Galvez 1563 (Phones: 0342-4573714, 154-573758 or 4574804).
Case analysis at national level
In the city of Epuyén (Chubut), 28 positive cases of hantavirus were confirmed and ten people died. In addition, there are 94 people who are under selective respiratory isolation to stop the spread of the virus, reported by the Ministry of Health of the Nation.
Hantavirus is a severe acute viral disease caused by the hanta virus that is transmitted to humans by contact with saliva, feces and urine of infected mice (mainly long-tailed mice) that once inhaled can be inhaled. There are different species of hanta virus and the one that caused the southern outbreak is the Southern Andes strain.
In Argentina, four endemic hanta regions have been identified: north (Salta, Jujuy), downtown (Buenos Aires, Santa Fe and Entre Ríos), northeast (Misiones) and southern (Neuquén, Río Negro and Chubut). Between 2013 and 2018, 111 cases of hantavirus deaths were reported in Argentina.
In the last few hours, a mortal case has also been confirmed in the rural area of the Gualeguay department, caused by the usual strain of the central region and not by the Southern Andean, which is more aggressive. In Entre Ríos, between 6 and 10 hunt cases reported by the Ministry of Health of Entre Ríos each year.
The case that was detected in Buenos Aires province is also native and is not related to the outbreak of the Epuyen epidemic. The same thing happens to the patient who died in Salta and the case reported in Jujuy.
