Which disease is caused by the bite of a female mosquito?

The correct answer is Dengue, Malaria.

Key Points

Dengue:

• Dengue is carried by the female mosquito Aedes.
• Its symptoms are nausea, vomiting, aches and pains, and rash.
• Whereas, vomiting blood, and bleeding from the nose or gums are symptoms of severe dengue.
• It can be prevented by the cleanliness and preventing mosquito bites.
• It can be cured by taking paracetamol and drinking fluids.

Malaria:

• Malaria spreads only by the disease-carrying mosquitoes.
• The vector of malaria is the female anopheles mosquito.
• Malaria spreads only when a female mosquito that has bitten a malaria patient bites another person.
• A blood test is done to check if a person has malaria or not.
• People with malaria get a fever with chills, sweating, headache, nausea and rigours.
• Malaria is caused by protozoan Plasmodium.
• In early times, the dried and powdered bark of the Cinchona tree was used to make medicine for malaria.
• Earlier people used to boil the bark powder and strain the water which was given to patients.
• Now tablets are made from this in the form of quinine, chloroquine is given to patients.

​Thus, Dengue, Malaria and Chikungunya are the diseases spread by mosquitoes.​Additional Information
