Malaria and it’s global attention
Malaria draws global attention in a cyclic manner, with interest and associated financing waxing and Waning according to political and humanitarian concerns. Currently, we are on an upswing, which should be carefully developed. Malaria parasites have seen eliminated from Europe and North America through the use of residual insecticides and manipulation of the environment and ecological characteristics, however, in many tropical and some temperate areas, the incidence of the disease is increasing dramatically.
Much of this increase results from a breakdown of effective control methods developed and implemented on the 1960s, but it has also occurred because of a lack of trained scientists and control specialists who live and work in the areas of endemic infection. Add to this, the wide spread resistance to the most effective anti-malaria drug, Chloroquine.
Developing resistance to other first are drugs such as sulfadoxine-pyrimethamine and resistance of certain vector species of mosquito to some of the previously effective insecticides and have a crisis situation, vaccine research has preceded for over 30 years, but as yet there is no effective product although research continues in many promising areas.
Global Strategy for MALARIA CONTROL
A global strategy for malaria control has been accepted, but there are critics who suggest that the single strategy cannot confront the wide range of conditions in which malaria exists and the reliance on chemotherapy without proper control of drug usage and diagnosis will select for drug resistant parasites, thus exacerbating the problem. Malaria control strategies are based on the biology of the mosquito, the epidemiology of the parasite, and human behavior patterns are needed to prevent continued upsurge in malaria in the endemic areas.
When one looks at the global distribution of malaria in the 21st Century. It is difficult to realize how widespread the disease has been and how its distribution has diminished during the past 150 years. This is important because in many places it may have the potential to return if appropriate climate conditions prevalent.
Malaria kills, yet decades ago doctors were confident that it could be beaten and control measures were beginning to be very effective with medicines working well. Now the picture is very different and malaria is re-emerging as very serious diseases.
Cerebral malaria caused by the plasmodium falciparum, parasite remains a major global health threat to people. Malaria is one of the leading killers of people and increasing drug resistance only exacerbates this (Cohen, 2002).
About 40% of the World’s population lives in areas where there is a risk of contracting the disease. There are about 300 million clinical cases diagnosed a year and about 1.5-2.7 million death a year. In addition, each year in the developed world travelers returning malaria regions dies from the disease.
Malaria is preventable or controllable and curable disease provided it’s diagnosed and treated promptly.
