*Warning over tropical virus risk*
The island of Reunion was hit by an outbreak of the Chikungunya virus
Travellers to the Indian Ocean are being warned about an increased risk
of the crippling Chikungunya virus.
The Health Protection Agency said there were 93 cases in people from the
UK by August this year, compared to an average of six in previous years.
Cases of the mosquito-borne virus have been recorded on Indian Ocean
islands and on the Indian mainland, the HPA's annual conference was told.
Travellers are advised to take standard precautions against mosquito bites.
These include using insect repellents and wearing long trousers and long
sleeved shirts, particularly during daylight when the Tiger mosquitoes
which carry the virus tend to be most active.
'Incapacitating'
Since March 2005 the number of cases of Chikungunya - Swahili for "that
which bends up - have been increasing in the islands of the Indian
Ocean, particularly the island of Reunion.
It is important that travellers to the region follow the usual health
advice on how to avoid being bitten by mosquitoes and other insects
Sir William Stewart, Health Protection Agency
The World Health Organisation estimates around 110,000 people were
affected in an outbreak on the island between March 2005 and February 2006.
The virus is spread by the bite of a mosquito and causes a non-fatal
self limiting illness characterised by a high fever with headache,
severe joint pains, and a rash with nausea and vomiting.
Symptoms usually appear between four to seven days after being bitten
and can persist for several weeks.
There is no vaccine against Chikungunya. Treatment consists of relieving
symptoms by using painkillers, taking plenty of fluids and resting.
Acute symptoms last from a few of days to a couple of weeks, whilst some
patients have reported incapacitating joint pain for up to several months.
Sir William Stewart, chairman of the HPA, said: "Although previously
centred on the islands of the Indian Ocean - Mauritius, Madagascar and
the Seychelles, cases in this region are declining whilst cases from
mainland India are increasing.
"This is due to an ongoing outbreak occurring on the mainland, with over
a million suspected cases to date.
"Therefore it is important that travellers to the region follow the
usual health advice on how to avoid being bitten by mosquitoes and other
insects."
