WHO-Recommended Spatial Repellents Are Effective Against Malaria, Suggests New Study

A new study has revealed that spatial repellents can prevent mosquito bites and offer significant protection against malaria. Researchers from the University of California-San Francisco, US, say that spatial repellents, also called spatial emanators can be a new class of insecticide that can be disseminated on something the size of a sheet of paper.
The main aim, here, is to offer protection for up to a year against mosquitoes that spread malaria, dengue, West Nile, yellow fever and Zika. This comes as a part of a systematic review in the journal eBioMedicine. As a part of this, the team analysed more than 25 years of data on some 1.7 million mosquitoes. The findings here concluded that this spatial emanator dispenses chemicals in the air and prevents more than one out of every two mosquito bites. The analysis came right after the World Health Organization recommended the use of spatial emanators. Ingrid Chen, Associate Professor of epidemiology and biostatistics at UCSF, while speaking to media said, "We finally have a new way to protect against mosquito bites, especially one that fills in some of the gaps of our existing method. It's lightweight, affordable, and easy to use, so it can be used to help save lives in all parts of the world." Malaria remains a major public health concern in many countries of the world, including India. It is one of those notorious infections that starts with a small, itchy bump and escalates to something far more serious. Early detection and timely treatment are critical to prevent serious complications as the disease progresses. Make sure to inspect your home and nearby surroundings as stagnant water attracts Malaria, especially during the rainy season. Additionally, personal protection measures such as mosquito repellents and wearing light-coloured, long-sleeved clothing are important in the fight against disease-carrying mosquitos. Children and pregnant women need to be extra cautious when venturing outside, particularly in the evening. Also, make sure you keep your neighbourhood clean. Regularly examine and get rid of any rubbish in and around your home. Mosquitoes frequently find comfortable places to hide in trash.
