In the last few years, 17,844 dengue cases were reported in the state with 10 deaths in 2017. Since then, it has been on the decline. In 2018, 4,848 cases and 4 deaths were reported.

Dengue is a viral disease spread by the bites of infected Aedes mosquitoes which can result in high-grade fever, retro-orbital pain, pain in the joints, common myalgia and rashes. Severe forms of dengue involve vomiting, haematemesis and bleeding gums. As there is no specific vaccine and treatment, cases are managed symptomatically. Dengue can be fatal, if not treated and managed on time, say experts. While severe covid cases can see an extreme fall in oxygen saturation level, dengue patients often witness a severe drop in platelets count.
A health expert said: “There is a fluctuation in number of dengue cases year after year. However, the recent decline in number of cases does not mean that it is subsiding. There can be multiple factors. Firstly, due to fear of covid, many people may be self-medicating and avoiding hospitals even if they have symptoms. As the dengue virus’s symptoms are sometimes similar to those of a viral fever, people may be confused and get treated for any other forms of viral fever.
“Another reason could be that due to lockdown, restrictions, no school and work from home, many of them may have avoided mosquito bites by staying inside their homes. However, we always need to be careful especially as we are approaching the monsoon season.”
