Dengue and Malaria

For the past 10 years, the number of Dengue cases has gradually increased in India. Dengue is a vector borne disease that is a major health threat globally. It is caused by the Dengue virus which is harboured by both Aedes Aegypti and Aedes Albopictus species of mosquitoes. Individuals infected with Dengue exhibit a wide spectrum of clinical symptoms ranging from asymptomatic, flu like illness, rashes to lethal complications like toxic shock syndrome.

There is no specific treatment for Dengue fever. Maintenance of patient’s body volume is critical to severe Dengue care. At present the main method to control or prevent the transmission of Dengue virus is to combat vector mosquitos and immunization in endemic areas.

Malaria is a potentially life threatening disease caused by parasites Plasmodium vivax, Plasmodium falciparum, Plasmodium malariae and Plasmodium ovale that are transmitted through the bite of infected Anopheles mosquitoes. People who have malaria usually feel very sick, with a high fever and shaking chills. Some people who have malaria experience cycles of malaria "attacks." An attack usually starts with shivering and chills, followed by a high fever, followed by sweating and a return to normal temperature. Malaria signs and symptoms typically begin within a few weeks after being bitten by an infected mosquito. However, some types of malaria parasites can lie dormant in your body for up to a year.

In most cases, malaria deaths are related to one or more serious complications like cerebral malaria, organ failure, pulmonary oedema, anemia, hypoglycaemia.

If you live in or are traveling to an area where malaria is common, take steps to avoid mosquito bites. To protect yourself from mosquito bites, you should:

  • Cover your skin.
  • Avoid water logging in homes which may serve to be a breeding ground for mosquitoes.
  • Apply insect repellent to skin and clothing.
  • Sleep under a mosquito net.

Besides supportive care, the medical team needs to decide on the appropriate antimalarial drug(s) to treat malaria. Physicians will administer the medication in pill form or as an intravenous antimalarial depending on numerous vectors and host dependant factors.
