It's caused by the Plasmodium parasite transmitted through the bite of infected female Anopheles mosquitoes. Malaria symptoms typically include cyclic fevers that occur every few days, along with chills, sweating, headache, muscle aches, fatigue, and sometimes nausea or vomiting. The severity of symptoms can vary depending on the species of the parasite. Diagnosis is confirmed through blood tests. Treatment involves antimalarial medications prescribed based on the type of malaria and its severity.
Dengue is caused by the dengue virus transmitted by Aedes mosquitoes. Symptoms include sudden high fever, severe headache (particularly behind the eyes), joint and muscle pain, rash, nausea, vomiting, and in severe cases, bleeding or a drop in platelet count leading to dengue hemorrhagic fever or dengue shock syndrome. Diagnosis is based on symptoms and confirmed by blood tests. Treatment focuses on supportive care to manage symptoms, as there's no specific antiviral treatment for dengue.
It's caused by the bacterium Salmonella typhoid, usually spread through contaminated food or water. Symptoms may include sustained high fever, headache, weakness, stomach pain, loss of appetite, and sometimes a rash. Diagnosis is confirmed through blood cultures or other laboratory tests. Antibiotics are commonly prescribed to treat typhoid fever.
