Dengue is a mosquito-borne viral disease transmitted by Aedes aegypti species mosquito. The disease is most common in India during the monsoon period and also few months after monsoon.
HOW DOES DENGUE TRANSMIT?
Aedes aegypti mosquito (also called tiger mosquito due to presence of characteristic stripes on their body) is the primary vector for the disease and is usually transmitted to humans through the bite of an infected mosquito. This species of mosquito are day biters and breeds in clean water mostly in household pots, discarded containers, broken coconut shells and open overhead tanks.
- Severe flu-like symptoms.
- High fever (40°C/104°F) accompanied by a severe headache.
- Severe body ache and joints pain.
- Rash and swollen glands.
- Pain behind the eyes.
- Abdominal pain and vomiting.
DENGUE SHOCK SYNDROME
A small percentage of dengue fever cases (1-2%) may lead to Dengue Shock Syndrome, if not treated, may eventually cause death. It is a syndrome characterized by decreased blood platelet count (thrombocytopenia) resulting in unusual bleeding (haemorrhagic manifestations) which leads to shock.
AN EASY WAY TO AVOID DENGUE DANGER
Aedes mosquito usually breeds in freshwater collections in artificial containers especially in plastic cups, flowerpots, broken bottles, overhead tanks that are not properly sealed.
- Periodic draining and removal of water from artificial containers at least once in a week.
- Use of mosquito nets and repellents.
- Covering, emptying and cleaning of domestic water storage containers on a weekly basis.
- Spraying insecticides in mosquito bread areas.
- Personal household protection such as window screens, coils, vaporisers and insecticide-treated materials.
Malaria is the most common life-threatening disease during monsoons caused by the species of Plasmodium parasite (Plasmodium ovale, Plasmodium falciparum, Plasmodium vivax). The disease is transmitted through the bite of an infected female anopheles mosquito that transmits the disease from one person to another person.
HOW DOES IT SPREAD?
Malaria is transmitted exclusively through the bite of Anopheles mosquito. Environmental factors like rainy season, humidity and temperature are conducive to mosquito breeding.
Symptoms of Malaria usually appear 10-15 days after the bite of infected mosquito which mainly include
- High fever 38°C (100.4°F) at periodic intervals.
- Severe chills and rigors – Classical symptoms of Malaria.
- Severe muscular pain and weakness.
INFECTED OR NOT? GET DIAGNOSED IMMEDIATELY
- The disease is usually diagnosed by the presence of parasite in the peripheral blood smear.
- Malaria caused by Plasmodium falciparum is most dangerous as it can turn into cerebral malaria which can be fatal.
