Insect-borne diseases, also known as vector-borne diseases, are illnesses caused by pathogens that are transmitted to humans and animals through the bites of insects such as mosquitoes, ticks, and flies. These diseases can have a wide range of symptoms and severity, ranging from mild flu-like symptoms to life-threatening conditions. Some common insect-borne diseases include malaria, dengue fever, Zika virus, Lyme disease, and West Nile virus. These diseases are typically more prevalent in tropical and subtropical regions where insect vectors thrive, but can also be found in other parts of the world. Research in this area focuses on understanding the biology and behavior of insect vectors, as well as developing strategies for controlling and preventing the spread of these diseases. This may involve studying the genetic makeup of pathogens, investigating ways to disrupt the transmission cycle, and developing vaccines or treatments to protect against infection. Ultimately, the goal of this research is to reduce the burden of insect-borne diseases on human and animal populations.
