5 Manitobans diagnosed with West Nile

Initial test results indicate five human cases of West Nile virus in Manitoba, provincial health officials said Thursday.
The cases are believed to be the first diagnoses of West Nile in Canada so far this summer.
All of the infected people are men over the age of 40. Two of the cases were found in residents of the Central Regional Health Authority in south-central Manitoba, while the other three were reported in the Interlake area.
Further testing and investigation is underway to confirm the cases as West Nile, and to determine when and where exposure to the disease might have occurred.
One positive result was identified by Canadian Blood Services from a blood donor. Four others were identified by a medical laboratory.
In 2005, 53 cases of West Nile were diagnosed in Manitobans, the first identified Aug. 4.
In previous years, the last week of July and the first three weeks of August have been the peak period for the risk of human exposure to the virus.
Although mosquito activity is low this year due to the hot, dry weather, Culex tarsalis mosquitoes —the type believed to carry the virus in Manitoba — thrive in the heat.
"Even though the mosquito counts are not very high, the proportion of mosquitoes that are turning up in our traps that are the Culex tarsalis type is significant," said Joel Kettner, the province's chief medical officer of health.
"It ranges from place to place, but it's in the order of about a third of the mosquitoes are Culex type rather than the nuisance type."
Culex mosquitoes positive for the virus have been found in more than a dozen Manitoba communities, including Selkirk, Carman, Steinbach, Boissevain, Carberry, Portage la Prairie, Gimli, Niverville, St. Andrews, Beausejour, Headingley, West St. Paul and Winnipeg.
The province ordered adult mosquito control measures in West St. Paul. The area was fogged with malathion earlier this week.
Precautions urged
Health officials have urged Manitobans to continue to take precautions against mosquito bites by reducing the amount of time spent outdoors from dawn to dusk, using mosquito repellent, making sure window screens are intact, and removing standing water from their homes and yards.
Provincial officials have not recommended local officials undertake adult mosquito control in any areas to control West Nile.
Most people who contract West Nile virus will not experience symptoms, according to local health officials. Of those who do, most show symptoms of West Nile fever, such as headache and fatigue.
In about one per cent of cases, the West Nile virus can cause a more serious illness called West Nile neurological syndrome, which can have serious complications, including weakness, paralysis, coma or death.
People with pre-existing medical conditions and older adults are at greatest risk for the more severe form of West Nile infection.
