Experts Warn Travelers Of Malaria Risk When Traveling to Africa and Asia

Say mosquito are more resistant to insecticides

As mosquitoes become ever-more a part of a problem, with resistance to insecticides becoming a norm, scientists are now claiming that there is a growing necessity for a better approach to control malaria.

The disease is considered widespread throughout all of the tropical and subtropical regions in a broad band around the equator. Areas that seem worst affected are Africa and Asia.

Symptoms for the disease tend to include a fever, headache, and other flu-like symptoms. If not treated properly, the symptoms can lead to coma or death. Now researchers at the London School of Hygiene and Tropical Medicine are looking for better ways to prevent malaria from spreading.

The researchers believe that simply targeting the mosquito’s natural breeding sites are likely to increase the necessary reduction in cases of malaria outbreaks in both Africa and Asia.

Experts say it should be noted the number of deaths have fallen significantly over the last decade, however there are still 600,000 people who were found to succumb to the disease in 2010.

Mosquito nets have not proved successful enough in the effort, and both Asia and Africa rely on proper protection from diseases like malaria because it can heavily affect their tourism numbers.

With insecticide also no longer working, scientists now warn that the insects are simply becoming increasingly bold and capable of spreading quickly throughout regions. They stated that authorities ought to use “larval source management” in order to help keep diseases like malaria under control. The way to do this is to simply kill off larva ponds, which are often small still water placements found almost anywhere. To do so, draining or flushing out the area is necessary, and then using larviciding spray to kill off remaining eggs in any standing water is needed.

The method has been found to reduce malaria cases up to 75% in areas where effectively used, as well as lower those infected with malaria parasites by nearly 90% in proper settings.

Those who plan to travel to Africa should thus continue using insecticides, netting, and any other available options to avoid catching the disease.
