Ways to prevent dengue virus from spreading in Kolkata

The World Health Organization (WHO), ranked dengue as the most critical mosquito-borne viral disease worldwide. Over the past 50 years, the disease has rapidly spread with a 30-fold increase globally.

Dengue is a human virus primarily transmitted by the Aedes Aegypti mosquito. It can be classified into four serotypes, where all of them can cause disease amongst human beings. Serotypes are group of microorganisms that are closely related.

In more than 100 countries, over 40 per cent of the world’s population is at a risk of dengue fever. In 2017, India witnessed a rise of 11,832 dengue cases. Amongst the total cases, over 18,000 people were affected by the vector-borne disease in Kolkata that year. A number of deaths were recorded in the city, which doctors attribited to dengue.

A consultant from AMRI Hospital said, “Symptoms of viral fever are very close to that of dengue. So, we are recommending blood tests to rule out dengue to all patients suffering from fever with allied symptoms like headache, body ache, nausea and weakness. Especially, if the symptoms don’t recede within 2-3 days, a dengue test must be done.”
