Dengue continues to claim lives in Latin America with over 400 deaths and nearly 161.000 infection cases according to this year’s reports from the different countries.
The disease which is endemic in parts of tropical Latinamerica is caused by a virus transmitted by the mosquito Aedes Aegypti and its symptoms are high fever, headache, vomiting and skin rashes. A more dangerous manifestation is the hemorrhagic strain which has a high mortality rate.
In 2010 the mosquito transmitted disease infected 1.5 million people and caused 1.020 deaths in Latam according to official reports.
So far this year dengue has killed 69 people in Paraguay out of 29.277 confirmed cases, with a mortality rate of 0.21%, but according to Health Minister Antonio Arbo the real contagion may range between 150.000 and 200.000 cases.
These numbers exceed those of 2011 when there were 62 deaths and 42.264 infections were reported. However the disturbing fact for Paraguay is that the disease had no fatal cases reported until 2007 (17 deaths and 9.040 infections) and since then has been expanding.
Although dengue is endemic in certain regions of Brazil, so far this year there has been a 49% reduction in fatal cases: 247 compared to 481 in the same period of 2011, according to an epidemiological report released this week by the Ministry of Health. The Ministry attributes the improved situation to the measures taken to assist the infected with a faster diagnosis and treatment.
