DIFFERENT TYPES OF MALARIA
There are 4 different species of human parasite:

Plasmodium falciparum (most serious) in sub-Sarahan Africa, Papua New Guinea and Amazon rain
forests of South America – death can occur within days

Plasmodium vivax in Indian sub-continent

P.Ovale mostly in Africa

P.Malariae mostly in Africa
The mosquito is responsible for transmitting many diseases, such as dengue fever, yellow fever, Japanese B encephalitis, but
malaria is the most serious of these tropical diseases. The malaria parasite enters your body when the mosquito bites you, and the
parasites first of all go to your liver, where they will stay for many days, and where they multiply over and over again. At this stage
you have no idea you have malaria, as you have no symptoms. The parasites then come out of the liver and invade your red blood
cells, and multiply again. After two or three days they will burst out of the red cells, and this is often when you get the symptoms of
malaria: shivering, sweats and fever, muscle pain and tenderness, headache, and sometimes diarrhoea and a cough. There are
four species of malaria, and one of them, called Plasmodium falciparum, is extremely dangerous. It is possible to die from this type
within 24 hours of developing the symptoms of malaria. Each year in the United Kingdom, we see up to 2,000 cases of malaria in
people who have returned from tropical areas with the disease, and we see on average nine deaths per year. None of these
deaths needed to happen. They usually occur because people have not taken the correct precautions. People living in the United
Kingdom will not have any protection against the malaria parasite, and indeed, people who used to live in a malarious country but
have left there will also not have protection against the disease, as you quickly start to lose your natural immunity within a matter of
months after leaving a malarious zone. So when we advise travellers within a consultation, we focus on malaria advice, with an A,
B, C, D approach. A is for awareness, understanding the risk and seriousness of the disease. B is for bite prevention, because you
significantly reduce your risk of malaria if you minimise the potential to get bitten. C is for the drugs we refer to as
chemoprophylaxis. Making sure that the most appropriate drug is selected, and that the course of tablets is always finished - this is
absolutely essential. And D is for diagnosis: understanding the symptoms of malaria and knowing to seek medical help
immediately. In the medical profession we regard this as a medical emergency.
When people come back from their holiday, and they're back into work, and they're feeling fine, they often decide there's no need
to carry on with their malaria tablets. It is absolutely essential to complete the course of malaria tablets, to help prevent malaria
breaking through.
Remember, malaria presents like a 'flu-like illness. Don't be confused by this. If you get the symptoms, it's essential that you go to
your GP's surgery and say that you have been abroad. You will need a test for malaria.
This will enable a speedy diagnosis and could potentially save your life. Look out for the symptoms of malaria, particularly in the
first three months, but up to a year after your trip, and make sure that you visit the doctor's surgery and let them know that you've
been to a malarious zone. Taken from www.malariahotspots.co.uk Jane Chiodini’s audio transcript. Taken from internet March
