Mosquito-borne Diseases

It may surprise you to know that mosquitoes are responsible for more human deaths than any other animal.

This is due to the fact they carry the parasite, PLASMODIUM, which carries MALARIA.  And this infection is on the rise.  Around 311,000,000 new infections and 900,000 deaths occur worldwide every year.

Australia is free of endemic Malaria, but, Aussies can catch the disease when travelling in tropical regions in Asia, Africa, and Central South America.  Most Australian cases of Malaria are contracted in Papua New Guinea, East Timor and Indonesia.


Ross River Virus (RRV) and Barmah Forest Virus (BFV) are two of the most important mosquito-borne-viruses causing human disease in Australia.

People suffering from RRV disease or BFV disease may develop a wide range of symptoms that are common to both.

They include painful and/or swollen joints, sore muscles, aching tendons, skin rashes, fever, tiredness, headaches and swollen lymph nodes.  Less common symptoms include sore eyes, a sore throat, nausea, and tingling in the palms of the hands or soles of the feet.

These symptoms may last from a few weeks to several months and in some cases up to a year, and they may recur suddenly and without warning.

Dengue Fever is another dangerous virus spread by mosquitoes.  It is a problem in many tropical and subtropical parts of the world, including Africa, Asia, South America and Australia.  Estimates suggest that around 100 million cases occur each year. [Read More]
