• Wuchereria bancrofti is commonly called the Filarial worm as it causes Filariasis or Elephantiasis in humans. It lives in the lymph vessels of man and female Culex mosquito is its secondary host and acts as a vector. Yellow fever (YF) is an African mosquito-borne infection of primates. It is caused by a virus of the Flavivirus genus of the Flaviviridae family. In its natural habitat, it is transmitted between monkeys by forest-dwelling primatophilic Aedes mosquitoes.
• Aedes mosquitoes cause yellow fever and filarial worm cause Filariasis.
• Malaria, caused by Female Anopheles mosquitoes pick up the parasites by feeding on infected humans. The parasites develop in a mosquito’s body for 10 to 18 days, then is passed on when the mosquito injects saliva while feeding.
• The Oriental Rat flea (Xenopsylla cheopis), also known as the tropical rat flea, is a parasite of rodents, primarily of the genus Rattus, and is a primary vector for bubonic plague and murine typhus. This occurs when the flea has fed on an infected rodent, and then bites a human. Diarrhoea is when your bowel movements become loose or watery. The definition of diarrhoea is passing loose or watery bowel movements 3 or more times in a day (or more frequently than usual). Diarrhoea occurs when the lining of the intestine is unable to absorb fluid, or it actively secretes fluid.
