Description

An infectious disease spread by mosquitoes that affects both humans and other animals is malaria. Frequent signs of malaria include fever, exhaustion, nausea, and headaches. In extreme circumstances, it may result in coma, jaundice, convulsions, or even death. Ten to fifteen days after being bitten by an infected mosquito, symptoms typically start to manifest. People may experience recurrences of the illness months after receiving inadequate treatment. People who have recently recovered from an illness typically experience milder symptoms when reinfected. If the individual does not continue to be exposed to malaria, this partial resistance vanishes over the course of months to years. Plasmodium-group single-celled microorganisms are the primary cause of malaria. It only spreads by mosquito bites from infected Anopheles species. The parasites from the mosquito's saliva enter a person's bloodstream through a mosquito bite. To mature and multiply, the parasites migrate to the liver. Humans can contract and spread five different Plasmodium species. While P. vivax, P. ovale, and P. malariae typically induce a lesser form of malaria, P. falciparum is responsible for the majority of deaths. Pertussis seldom infects people with illness. Usually, fast diagnostic procedures based on antigens are used to identify malaria after microscopic inspection of blood on blood films. There are techniques that employ the polymerase chain reaction to find the parasite's DNA, but because they are costly and complicated, they are not frequently used in places where malaria is a problem.

Adults with malaria commonly experience headache, exhaustion, abdominal discomfort, and muscle pain in addition to chills and fever, which typically occur in periodic strong episodes lasting about six hours, followed by a period of sweating and fever relief. The more common symptoms in children are fever, cough, vomiting, and diarrhoea. Initial signs of the illness, which are present in all malaria species, resemble flu-like symptoms and can be mistaken for other illnesses such sepsis, gastroenteritis, and viral disorders. Hemolytic anaemia, jaundice, haemoglobin in the urine, retinal damage, seizures, headache, fever, shivering, joint pain, vomiting, and other symptoms are possible presentations. The most well-known sign of malaria is paroxysm, a cycle of sudden coldness, shivering, fever, and sweating that happens every two days (tertian fever) in infections with P. vivax and P. ovale and every three days (quartan fever) in infections with P. malariae. P. falciparum infection might result in a more mild, nearly constant fever that recurs every 36–48 hours. Although they can appear months after infection with some P. vivax strains, symptoms usually start 10 to 15 days after the initial mosquito bite. Travelers taking prophylactic treatment for malaria may experience symptoms after stopping the prescription. There are various major adverse effects of malaria. In up to 25% of adults and 40% of children with severe P. falciparum malaria, respiratory distress can ensue. Possible causes include severe anaemia, noncardiogenic pulmonary oedema, concurrent pneumonia, and respiratory compensation of metabolic acidosis. Even though it is uncommon in young children with severe malaria, 5%-25% of adults and up to 29% of pregnant women get acute respiratory distress syndrome. Malaria and HIV co-infection increase mortality. Blackwater fever, in which haemoglobin from lysed red blood cells spills into the urine, is characterised by kidney failure. P. falciparum infection can cause cerebral malaria, a severe form of the disease that involves encephalopathy.

It is linked to retinal whitening, which could be a helpful clinical indication in separating malaria from other fever-causing conditions. In addition to a severe headache, low blood sugar, and haemoglobin in the urine with kidney failure, an enlarged spleen, liver, or both of these organs may also develop. Spontaneous bleeding, coagulopathy, and shock are possible complications. Malaria is a major cause of stillbirths, infant deaths, miscarriages, and low birth weight in pregnant women, mainly P. falciparum infection but also P. vivax infection.
