Malaria is an infection caused by a parasite, which is passed on through the bite of an infected mosquito.
What are the symptoms of malaria?
- a slow rising fever that escalates to a rapid temperature rise and fall
- excessive sweating
- generally feeling unwell
- anaemia and associated symptoms.
How is malaria diagnosed?
A clinical diagnosis is made based firstly on the patient's symptoms.
However, the first symptoms of malaria (most often fever, chills, sweats, headaches, muscle pains, nausea and vomiting) are often not particularly specific and are also found in other diseases.
In severe malaria, the symptoms (confusion, coma, neurologic focal signs, severe anaemia, respiratory difficulties) are more striking and may lead to a quicker diagnosis.
A diagnosis based on physical symptoms should always, if possible, be confirmed by a laboratory test for malaria.
How to avoid catching malaria
Infected mosquitoes are only present in certain parts of the world. Therefore travellers to tropical regions of Asia, Africa, and Central or South America can be at risk.
When in these malarial areas you can lessen the risk of being infected.
- avoid outdoor activity around dawn and dusk when mosquitoes are most active
- wear loose, long, light-coloured clothing
- use mosquito repellents
- do not wear perfumes, colognes or aftershave
- use anti-mosquito devices indoors
- use mosquito nets which have been treated with repellents or insecticides (especially if windows don't have flyscreens).
How is malaria treated?
Treatment consists of anti-malarial medications. The particular medication administered will depend on the species of parasite and any associated medication resistance.
In most cases, urgent hospital assessment and management is needed.
