Dengue and malaria are two life-threatening diseases originating from mosquitoes, which unfortunately are everywhere in Malaysia. But don't worry too much, this article will tell you that these 12 plants are natural and effective mosquito repellents.
Mosquito-related diseases are very common in Malaysia, with a large number of cases reported every year. According to a recent report by The Star, in 2019 alone, there were 130,101 dengue cases and more than 182 deaths, the highest number ever recorded in Malaysia. In Asia, my country ranks second in the number of reported cases of dengue fever.
I believe everyone already knows that dengue is caused by the breeding of Aedes mosquitoes in stagnant water and changes in hot and rainy seasons. The mosquitoes not only bring dengue, but other diseases, including chikungunya and Zika. But thankfully, there are no deaths or bleeding cases in Malaysia so far.
As for malaria, there is a report in the News Straits Times that there are 4,000 to 5,000 cases in Malaysia each year. Most of them are human-to-animal transmission, which means that the source of this transmission comes from the parasites in monkeys being bitten by infected mosquitoes on humans.
Most of the malaria cases reported were from Sabah, Sarawak and some rural areas in Peninsular Malaysia. Although you may live in cities, you are still at risk of contracting mosquito-borne diseases, especially dengue. Therefore, it is very important to keep the home clean, and cooperate with the occasional mosquito spraying work organized by the Ministry of Health.
