Population growth also strains the limited health facilities available in poorer countries.

Thousands of children are killed by diseases everyday. And that could have been prevented if medical and health facilities have been made available to them.

Malaria, which is easily spread by the Anopheles mosquitoa is top killer in the tropics. Malaria has been a serious health problem throughout history. Its threat is still serious today and this can be shown by the numerous outbreaks of malaria in South East Asia.

Malaria affects millions of people every year. It kills more than twice as many people each year as does Aids.

Malaria is making a big comeback in the world. According to the World Health Organisation, the disease claims at least one million lives each year. The resurgence is due mainly to the increasing resistance of the disease to anti-malaria drugs.

This has prompted the WHO to launch a "Roll Back Malaria" Project to curb the disease. It will aim to develop the health care facilities of poorer countries, where most victims live and to create new technologies to fight the disease.

In poorer countries, civil conflicts and environmental changes are key reasons for the resurgence of the disease, given that it thrives in situations where medical attention is delayed.

Costing US$1 Billion, the programme hopes to halve the number of Malaria deaths worldwide.

Most of the deaths in Africa are children. Health experts had warned as early as 1997 that Malaria would be deadlier than Aids. But countries often ignore the warnings as they do not feel threatened by it.
