April 25, 2018 is World Malaria Day, as recognized by the World Health Organization. In 2016 alone, there were 216 million cases of malaria worldwide, and 445,000 deaths. In other words, it’s an extremely big deal. Sometimes something as simple as a mosquito net can prevent infection, and with appropriate medical treatment, malaria can be cured. A lot of money is being spent on an effort to eradicate malaria entirely. Speaking as someone who has experienced malaria, I hope to see the day when that particular parasite goes extinct.
