Global Warming Increases Risk Of Malaria, Dengue: Study

In a new study it is found the global warming may expose millions of more people to malaria. Scientists say the mosquitoes move to higher altitudes.

The study is published in the US journal Science. It is said the tropical highland areas in central America, southern America, Asia and Africa are at risk.

In 2012 malaria killed about 620,000 people.

The researchers warn host of diseases will spread easily due to global warming. A one-degree-Celsius temperature increase in Ethiopia alone will lift the area where the parasite-bearing mosquitoes-based disease can occur by 150 metres.

According to Menno Bouma of the London School of Hygiene and Tropical Medicine, about nine million people in the band will be additionally affected by the intensity of malaria.

Bouma scrutinized malaria records between 1993 and 2005 in Ethiopia and between 1990 and 2005 in highland regions of California.

Ecologist Mercedes Pascual from University of Michigan said people who are living in the tropical highland areas never built up immunity to malaria and will be more vulnerable to it.

The study also suggests other tropical highland areas such as parts of Peru, Uganda, Kenya, Ecuador, Tanzania, Madagascar, India, Pakistan, Papua New Guinea, Nepal and Ecuador too are likely to be affected similarly.

Malaria can be prevented with medicines, insecticides and nets. Symptoms of it include vomiting, headache and fever. It can also kill a person by disrupting blood supply to vital organs if left untreated.

Other diseases occurred by mosquitoes include Dengue, which is spreading at an alarming rate.
