Dengue has hit the heart of Indian, our national capital New Delhi. As many as 477 cases have been reported in August itself which is very high when compared to 11 cases repoted in August 2013 and 142 cases indetified in August 2014.
Every year in the monsoon season dengue cases rises in the country as warm and humid condition is best for mosquitoes to breed. Dengue is caused by virus carried by Aedes mosquito. These mosquitoes do not breed in contaminated water, but they lay their eggs in fresh water which makes it more difficult to control breeding of Aedes mosquito.
Dengue has four types — DEN-1, DEN-2, DEN-3 and DEN-4. If a person becomes immune from one serotype still there are high chances that the person will get dengue from other serotypes. In addition, eight different species of Aedes mosquito can cause dengue. Out of eight species, Aedes aegypti and Aedes albopictus are the two most prominent species that causes dengue.
It is very interesting to know that only female mosquito feed on human blood, this is due to the fact that they need blood to mature their eggs. Female mosquito can give up to 12 eggs for four to five times during their life cycle. These eggs can survive for months. Also, Aedes mosquito lives near humans and can fly for over 400m. Since, dengue is a life threatening disease, here are few symptoms and prevention tips.
- Dengue starts with severe joint pain and muscular pain.
- Swollen Lymph nodes
- Severe headache
- Body temperature rises which get converted into fever
- Since Aedes mosquito breed in water, so do not let stagnant water in buckets and any other utensils.
- In summers, people use water coolers, its always a safer option to put kerosene oil in the cooler. This way oil forms a thin layer over water and restricts oxygen to go into water and also prevents eggs to breed.
- Wear full sleeves cloth as it will refrain mosquito from biting you.
- Try mosquito repellent like spray and coil to keep mosquitoes out of your house.
