Mosquitoes, Dengue Fever, and the Quest for a Dengue Vaccine

  Dengue fever is a viral infection that affects millions of people around the world every year. It is transmitted by the bite of infected mosquitoes, mainly the Aedes aegypti species, which are found in tropical and subtropical regions. Dengue fever can cause a range of symptoms, from mild to severe, and sometimes even fatal. There is no specific treatment or cure for dengue fever, and the only way to prevent it is to avoid mosquito bites and control the mosquito population. In this blog post, we will explore what dengue fever is, how it affects people, and what efforts are being made to develop a vaccine against it. What is dengue fever? Dengue fever is caused by one of four types of dengue virus (DENV), which belong to the flavivirus family. The virus enters the human body through the saliva of an infected mosquito, and then multiplies in various tissues and organs, especially the lymph nodes, spleen, liver, and blood vessels. The virus can also infect some immune cells, such as mac

Filariasis and Its Health Challenges: A Mosquito-Borne Threat

Filariasis is a neglected tropical disease caused by parasitic worms. It affects over 120 million people worldwide. While often overlooked, filariasis poses significant health challenges, causing disfigurement, disability, and social stigma. What is Filariasis? Filariasis is a group of mosquito-borne infections caused by parasitic worms called filariae. The most common types of filariasis are lymphatic filariasis (LF) and onchocerciasis (river blindness). Lymphatic filariasis affects the lymphatic system, which drains excess fluid from the body. Chronic infection can lead to lymphedema, a painful swelling of the limbs, genitals, and other tissues. Onchocerciasis infects the eyes and skin, causing nodules under the skin and potentially leading to blindness. How is Filariasis Spread? Filariasis is spread through the bites of infected mosquitoes. The mosquito ingests the parasite larvae while feeding on an infected person, and the larvae mature and reproduce inside the mosquito. When the
