प्रश्न
How does the transmission of the following disease take place?
Malaria
उत्तर
A protozoan called Plasmodium is responsible for this disease. Various species of Plasmodium (such as Plasmodium vivax, Plasmodium malaria, Plasmodium falciparum) and Plasmodium ovale are responsible for malaria. Out of these, malignant malaria caused by Plasmodium falciparum is the most serious and fatal. Due to its infection, blood cells get blocked due to thrombosis and the patient dies. The female Anopheles is the vector, i.e. the one that transmits the disease. When a female Anopheles mosquito bites an infected person, the parasites enter his body and when an infected female mosquito bites another healthy human, the sporozoites enter the human body through the saliva of the female mosquito. In malaria, fever keeps recurring after a certain period (48 or 72 hours). In this, red blood cells keep getting damaged continuously.
