Virus cases up 150pc

The Department of Health has voiced its concern about the alarming increase in Ross River virus cases in the South West.

There has been rise of about 150 per cent in the virus compared to this time last year, with no less than 232 cases reported since July 1, 2011.

A Department of Health spokesman said the reason for the increase was due to a La Nina weather condition.

‘‘We are currently experiencing a La Nina weather condition that leads to warmer minimum temperatures, average maximum temperatures and above average rainfall,’’ he said.

‘‘Under La Nina weather patterns we also see high tides and storm surges leading to the inundation of low lying land.

‘‘These factors combined mean we have ideal conditions for mosquito breeding.’’

The shires of Capel and Busselton appear to be the most active spots in the South West, but there is a general increase in the entire region.

The symptoms of Ross River virus include unbearable joint and muscle pain, rashes and severe tiredness.

The only way a patient can be diagnosed with Ross River virus is by a specific blood test ordered by a doctor.

It can take up to three months to recover from the virus, so it is important for people to take personal measures to prevent the virus.

Director of communications at Australian Medical Association WA Robert Reid said the increased mosquito population needed to be controlled.

‘‘We are concerned about the amount of money that the State Government is putting into control of these mosquitoes,’’ Mr Reid said.

‘‘There’s only $750,000 a year and we think it should be a lot more.

‘‘We are also concerned about the degree of consultation between local governments and the State Government about spraying operation and we have had reports about the consultation not working very well.’’

AMA vice-president Dr Richard Choong urged residents to be aware of the precautions to avoid the virus.

‘‘Residents should also be aware of the steps they can take to reduce the risks of contracting Ross River such as covering up and being aware of the potential dangers,’’ Dr Choong said.
