Question

Name the disease in which the number of platelets reduces to 25,000- 30,0000 per cu mm of blood.

Answer 1

Hint: Dengue is the disease caused by the mosquitoes. The virus is transferred by female mosquitoes mainly of the species Aedes aegypti. These mosquitoes are also vectors of chikungunya, yellow fever etc.

Complete answer:
 In normal adult human beings the number of platelets in the blood is about 1,50,000-3,00,000 per cu mm of blood. There are some diseases in which the count of the platelets reduces acutely and can be fatal. The reduced number of platelets in the blood inhibits the clotting potential of a human and this will lead to excessive blood loss.
Dengue is the disease in which the blood count of platelets reduces to about 25,000- 30,000 per cu mm of blood which is a very high risk for the patients. Dengue fever is the tropical mosquitoes disease which is caused by the dengue virus. The symptoms of dengue fever can be started showing in about 3-14 hours days after the infection. The main symptoms of dengue fever are high fever, headache, vomiting, muscle and joint pain, skin rashes and sometimes fever accompanied by the cold. Dengue is spread by the various species of the female mosquitoes. The female mosquitoes belong to the genus Aedes and mainly the Aedes aegypti are the main dengue spreading mosquitoes.

Note: A vaccine for dengue fever has been introduced and is commercially available in several countries. Treatment of acute dengue is supportive and includes giving fluid either by mouth for moderate disease.
