6 Devastating Tropical Diseases That You Need to Know About Today
Introduction
Tropical diseases are a major health concern in many parts of the world. These diseases are caused by viruses, bacteria, parasites, and other pathogens that are prevalent in tropical regions with high humidity and temperatures. Despite being preventable and treatable, these diseases continue to devastate many countries, especially those with limited healthcare resources. In this article, we’ll discuss six of the most devastating tropical diseases that you need to know about today.
Malaria
Malaria is a mosquito-borne disease that is caused by the Plasmodium parasite. It is prevalent in many tropical and subtropical countries in Africa, Asia, and South America. According to the World Health Organization (WHO), there were an estimated 229 million cases of malaria worldwide and 409,000 deaths in 2019. The disease can cause fever, chills, and flu-like symptoms, and if left untreated, can lead to severe complications and death. Prevention measures include the use of mosquito nets, insect repellent, and antimalarial medication.

Dengue fever is a viral disease that is transmitted by the Aedes mosquito. It is common in tropical and subtropical regions, including Southeast Asia, Latin America, and the Caribbean. According to the WHO, there were an estimated 100 million cases of dengue fever worldwide in 2019. The disease can cause fever, headache, joint pain, and a rash, and in severe cases, can lead to dengue hemorrhagic fever, which can be fatal. Prevention measures include wearing long-sleeved clothing, using insect repellent, and eliminating mosquito breeding sites.
Chikungunya
Chikungunya is a viral disease that is transmitted by the Aedes mosquito. It is prevalent in Africa, Asia, and the Indian subcontinent, as well as in tropical regions of the Americas. According to the WHO, there were over two million suspected cases of chikungunya worldwide in 2019. The disease can cause fever, joint pain, and a rash, and in some cases, can lead to chronic joint pain. Prevention measures include wearing long-sleeved clothing, using insect repellent, and eliminating mosquito breeding sites.
Zika Virus
Zika virus is a viral disease that is transmitted by the Aedes mosquito. It is prevalent in Africa, Asia, and the Americas, and has been linked to microcephaly in infants born to infected mothers. According to the WHO, there were over 17,000 confirmed cases of Zika virus in 2019. The disease can cause fever, rash, joint pain, and conjunctivitis, and in pregnant women, can lead to birth defects.

Conclusion
Tropical diseases continue to be a significant global health threat. They affect millions of people worldwide, causing suffering and death, and placing a significant burden on healthcare systems. Thankfully, most of these diseases are preventable and treatable through simple measures such as vaccination, insect repellent, and environmental control. By raising awareness and implementing effective prevention and control measures, we can mitigate the impact of these diseases and improve the health and wellbeing of those living in tropical regions.
