Does all malaria kill without treatment?
No. There are five main species of malaria which infect humans: Plasmodium falciparum, P. vivax, P. ovale, P. malariae and P. knowlesi. Of these, P. falciparum is the most deadly, and can often cause death if left untreated.
The other four may also result in death, but more rarely, and usually only in high risk individuals, such as young children, pregnant women and people with weakened immune systems. Given the seriousness of the symptoms and the possibility of death in all cases, it is very important to seek medical advice if you suspect you have malaria. Once given accurate diagnosis of which type of malaria you have, you can be given appropriate treatment.
