Authorities of the Jujuy Ministry of Health yesterday [8 Apr 2019] confirmed that 11 cases of hantavirus [infections] are confirmed in the province, distributed in the localities of San Pedro, Palma Sola, Libertador General San Martin, and Calilegua. "The majority of the affected people have a history of having gone fishing or hunting in the forest," and so "probably did not take the necessary precautions", stated the Jujuy Subsecretary of Prevention for Health, Veronica Serra.
The official stated that 11 hantavirus [infection] cases have been confirmed so far this year , "all of them in the Jujuy Ramal [area]' she said.
Concerning the medical treatment of the infected people, she indicated that some have "greater cardiopulmonary complications than others, but progress favourably," she stated.
Jujuy has registered cases of hantavirus [infections] since 1996, with a yearly average of 17, which generally appear in the summer season. In 2018 there were 7 cases with no fatalities.
Taking these data into account, so far in 2019 there are now 57% more cases compared to last year .
"The majority of the cases are registered until the month of April and we hope that they are maintained within [numbers] expected for this year ," she said, and recalling that more than 20 years ago the cases, "were much higher."
The confirmed [patients] this season were [infected] in the cities of San Pedro, Libertador General San Martin, Calilegua, and in the localities of Aguas Calientes, Palma Sola, and El Remate. Hantaviruses cause an acute virus disease. Wild mice (mainly the long-tailed] mouse) transmit [the virus] to people, and shed the virus in saliva, faeces, and urine.
The most frequent route of infection is by inhalation and occurs when breathing in open or closed places (sheds, gardens, pastures), where faeces or urine of infected rodents shed the virus, contaminating the environment. Other ways to contract the disease are by direct contact, that is to say, touching live or dead infected rodents or the urine or faeces of these rodents and person to person when there is close contact with an infected person during the 1st symptomatic days, through aerosols.
The symptoms of hantavirus [infections] are flu-like: fever, muscle pain, chills, headache, nausea, vomiting, abdominal pain, and diarrhoea. After a few days, respiratory difficulty may appear and get worse.
[The hantaviruses responsible for these 11 cases are not stated in the report above. An earlier report from Jujuy province this year (2019) apparently presumed that the hantavirus involved in that case was Laguna Negra, although it is not stated that this virus had been laboratory confirmed. As noted in ProMED-mail archive no. http://promedmail.org/post/20110430.1348
, several hantaviruses have been associated with human infection and hantavirus pulmonary syndrome in Argentina: Andes virus (western Argentina, in the long-tailed pygmy rice rat host, _Oligoryzomys longicaudatus_); related Andes-like viruses Hu39694 (in central Argentina; rodent host unknown); Lechiguana (in central Argentina in the yellow pygmy rice rat, _O. flavescens_); Oran (in northwestern Argentina in _O. longicaudatus_); Bermejo (western Argentina in _O. flavescens_); and Laguna Negra (in northern Argentina in _Calomys laucha_). Without laboratory confirmation, it is not possible to say with certainty which hantavirus was involved. Andes virus seems unlikely in this case. - ProMED Mod.TY]
