Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. According to the World Health Organization (WHO), in 2021 there were roughly 247 million cases of malaria worldwide, putting nearly half the world’s population at risk of the disease. However, the risks and burdens of malaria are highly disproportionate. The WHO African Region is home to 95% of malaria cases. Malawi, a small country in southeastern Africa, is one of the areas where malaria wreaks havoc. The Malawi Ministry of Health (MoH) states that malaria is not only the leading cause of death in Malawi, but it also claims about 3 lives a day. The MoH is hopeful that adding the malaria vaccine to its routine immunization program could help lower both cases and deaths.

Catherine the Great is a well-known historical figure, but there’s so much more to learn about this Russian empress than what we see on the surface. One of the more compelling facts is that she sparked an interest in inoculation against viruses like smallpox.

Babesiosis is an infectious tick-borne disease that comes from protozoa, which are microorganisms. There are over 100 species of Babesia, common in animals like deer, mice, horses, cats, and dogs. Only two strains of Babesia are known to infect humans. Recently, cases of babesiosis have more than doubled in some Northeastern states between 2011 and 2019. Many people who develop babesiosis are asymptomatic, while others experience flu-like symptoms (chills, sweats, and muscle aches). People with compromised immune systems or other risk factors are at risk of having severe or fatal cases. The disease was rare for decades in the United States but is now endemic in 10 states in the Northeast and the Midwest. Experts are trying to determine why cases are climbing.

Anyone who is sexually active is at risk of getting gonorrhea. Gonorrhea is a sexually transmitted infection (STI) that if left untreated can lead to serious and permanent health issues, including infertility. About 82.4 million people were newly infected with gonorrhea in 2020 alone. Contracting gonorrhea can have unpleasant symptoms, but it can be treated and even cured with antibiotics. However, with the growing number of cases, gonorrhea is becoming antibiotic-resistant. A vaccine specifically for gonorrhea doesn’t exist yet. But, recent studies suggest a side effect of meningitis vaccines guarding against gonorrhea.

Mosquitoes can be more than just a nuisance, as some can carry parasites and viruses like West Nile and dengue fever. According to the World Health Organization (WHO), mosquito-borne diseases cause around 725,000 deaths every year. Fortunately, there may be a solution to preventing these diseases altogether. Entomologist Naoki Yamanaka suggests chemically halting the maturation of mosquitoes. By preventing them from developing and mating, they won’t be able to spread viruses among humans. It’s an exciting possibility for improving public health.
