Expert Talk: Increase In Dengue Cases Due To Climate Change

The elevated carbon dioxide levels contribute significantly to an increase in global temperatures, which, in turn, worsens the outbreak of dengue fever all around us. Climate change can even affect the disease indirectly through a decrease in agriculture, which may lead to an increased urbanization and further spread of disease in cities.

Dengue is mosquito borne disease caused by the bite of an aedes aegypti mosquito. An individual suffering from dengue experiences high grade fever, headache, body pain, nausea, vomiting and abdominal pain In the febrile phase which lasts for a period of 5 to 7 days.

With the onset of monsoons the number of dengue cases seems to be on a constant rise. Hospitals and outpatient clinics are seeing a number of fever cases, especially dengue cases.

Transmission of Dengue

The virus is transmitted to humans through the bites of infected female mosquitoes, primarily the Aedes aegypti mosquito. A few other ways it can be transmitted are:

  • Human-to-human transmission
  • Maternal transmission
  • Rare cases of transmission via blood products, organ donation and transfusions

Symptoms of Dengue

In an exclusive interaction with OnlyMyHealth Dr. Aafrin Shabbir, Senior Consultant - Internal Medicine, Gleneagles Global Health City, Chennai explains that in the critical phase or hemorrhagic phase there may be drop in platelets which may manifest as petechiae in skin .

The COVID-19 pandemic is placing immense pressure on the health care and management systems across the globe. The World Health Organisation also emphasised the importance of sustaining efforts to prevent, detect and treat vector-borne diseases during and post the pandemic, as case numbers increase in several countries and place urban populations at highest risk for both diseases. The combined impact of the COVID-19 and dengue epidemics could have devastating consequences on the populations at risk and therefore, a few standards should be set and adhered to.
