Malaria : Symptoms
Symptoms of malaria can develop as quickly as 7 days after you're bitten by an infected mosquito.
Typically, the time between being infected and when symptoms start (incubation period) is 7 to 18 days, depending on the specific parasite you're infected with. However, in some cases it can take up to a year for symptoms to develop.
The initial symptoms of malaria are flu-like and include:
- a high temperature of 38C or above
- feeling hot and shivery
- muscle pains
- generally feeling unwell
These symptoms are often mild and can sometimes be difficult to identify as malaria.
With some types of malaria, the symptoms occur in 48-hour cycles. During these cycles, you feel cold at first with shivering. You then develop a high temperature, accompanied by severe sweating and fatigue. These symptoms usually last between 6 and 12 hours.
The most serious type of malaria is caused by the Plasmodium falciparum parasite. Without prompt treatment, this type could lead to you quickly developing severe and life-threatening complications, such as breathing problems and organ failure.
