The virus of Chikungunya
The virus of chikungunya is transmitted by mosquitoes and especially by the asian tiger mosquito.
Chikungunya was first identified in Africa. Its symptoms are joint pain, fever, headache, conjunctivitis, and rash.
Chikungunya car be transmitted to humans by mosquito bites. The dengue mosquito (Aedes aegypti), and the Asian tiger mosquito (Aedes albopictus) are its primary carriers.
This virus hasn’t colonised Australia yet.
168 cases of chikungunya has been declared in Australia since 2002, with the majority of infections acquired by travellers in Malaysia, Indonesia, and India.
Danger to Australia
We only know that some parts of Australia have the right kind of environmental conditions for the asian tiger mosquito to spread.
The asian tiger mosquito is alreadt installed in Queensland, so it’s the most likely place for the chikungunya to become established, but several other places could also be favorable.
The Asian tiger mosquitoes may also colonise the Australian mainland from their springboard on the Torres Strait islands, where we know they have been since 2004.
