What is Malaria?
Malaria is an infectious disease that is considered a major public health threat, particularly in Africa, because it is one of the leading causes death and illness among children and other vulnerable populations. One million children die each year from malaria in Sub-Saharan Africa. This disease also has negative social and economic consequences on affected populations - it is one of the causes of poverty.
How is Malaria Transmitted?
The mosquito is considered the main malarial vector in Africa, which transmits the parasite that is responsible for the disease to humans. Mosquitoes have the capacity for long-term survival, which is how the malarial parasite develops and is later transmitted to humans when mosquitoes bite them. Once the parasite is transmitted to humans, it reproduces in the liver and spreads to the rest of the body through the red blood cells causing illness.
So What Does Global Warming Have to Do With it?
Recent changes in the environment and the global climate are a direct and indirect result of human development and globalization. Global warming is one of the major factors that have led to increased temperatures and subsequent increase in malarial outbreaks. Temperature is considered a key factor in malaria transmission because higher temperatures mean faster parasite development. Mathematical models have illustrated how climate (such as humidity, temperature, and rainfall) affects the reproduction rate of the disease because it increases mosquito survival time and reduces the incubation time of parasites. Excessive rainfall encourages the development of parasites by increasing humidity, potential breeding sites, and the lifespan of mosquitoes.
Did you know? The most affected areas in countries such as Africa and South America are located near the equator line and generally have climates that are conducive to mosquito development.

Factors that contribute to global warming and El-Nino cycles include human activities that have led to changes in the ecology of the land, such as:
What Can Be Done?
Vector control strategies that effectively reduce mosquito to human contact and mosquito survival time can reduce the risk for malaria outbreaks and include the following:
Other measures include increased surveillance of affected areas and effective case management of affected populations and research on drug and vaccine development. Unfortunately, this disease often does not receive top priority for funding from countries that have eradicated this disease years ago. So please consider donating to this cause to help increase access to preventive resources (see resources below).
We also have to be conscious about the our actions and the impact that they have on the global climate. Ultimately, increased temperatures, even by one degree, have a negative impact on global health, particularly on poorer countries.
What’s Being Done to Eradicate Malaria?
In the past, pharmaceutical companies didn’t pursue development of a malaria drugs and vaccines because they felt that they wouldn’t bring in enough profits. Fortunately, the Bill and Melinda Gates Foundation provides funding and grants to support malaria programs and malaria drug and vaccine development. One such program is the PATH Malaria Vaccine Initiative that is attempting to develop the first malaria vaccine. This would mean that rates of malaria could significantly be reduced, leading to healthier populations that could pave the road towards their country’s economic development.
For far too long, malaria has been a forgotten epidemic. If we expand malaria control programs and invest in research, we can stop this tragedy.
