Mosquito-borne Illnesses

Study Notes

Mosquito-borne Illnesses

Mosquitoes are responsible for spreading various diseases to humans, causing significant morbidity and mortality worldwide. Some of the most common mosquito-borne illnesses include:

1. Malaria

Caused by the Plasmodium parasite
Transmitted through the bite of an infected female Anopheles mosquito
Symptoms: fever, chills, flu-like symptoms, and anemia
Can be fatal if left untreated, especially in children and pregnant women

2. Dengue Fever

Caused by the dengue virus
Transmitted through the bite of an infected female Aedes mosquito
Symptoms: high fever, severe headache, joint and muscle pain, and rash
Can lead to hemorrhagic fever, which can be life-threatening

3. Zika Virus

Caused by the Zika virus
Transmitted through the bite of an infected female Aedes mosquito
Symptoms: mild fever, rash, joint pain, and conjunctivitis
Linked to birth defects, such as microcephaly, and neurological disorders

4. Yellow Fever

Caused by the yellow fever virus
Transmitted through the bite of an infected female Aedes mosquito
Symptoms: fever, chills, nausea, and vomiting
Can lead to severe hemorrhagic fever and death

5. Chikungunya

Caused by the chikungunya virus
Transmitted through the bite of an infected female Aedes mosquito
Symptoms: fever, joint pain, rash, and swelling
Can cause chronic arthritis and other complications

6. West Nile Virus

Caused by the West Nile virus
Transmitted through the bite of an infected Culex mosquito
Symptoms: fever, headache, body aches, and rash
Can lead to neurological disorders and death

7. Filariasis

Caused by the Wuchereria bancrofti parasite
Transmitted through the bite of an infected Culex mosquito
Symptoms: swelling of the limbs, fever, and chills
Can lead to elephantiasis, a condition characterized by severe swelling and disfigurement

It is essential to take preventive measures against mosquito bites, such as using insecticides, wearing protective clothing, and eliminating breeding sites, to reduce the risk of contracting these diseases.
