Summers bring with them a number of problems and the major problem is that of mosquitoes. After the outburst of the West Nile virus in the year 2004, which resulted in 127 positive cases in Mesa County and four deaths, one case of the virus has been detected this year.

The spread of the virus initiated, when the bug came in contact with the birds of the corvid family, including crows, ravens and magpies.

However, after 2004 diagnosis, the virus had disappeared. But, it again appeared in 2009, when one person died and two were reported with the virus.

This year, a case of the West Nile virus has been confirmed at in the Weld County by the Colorado Department of Public Health and Environment on Friday.

After the elimination of most of the local corvid bird population in 2004, it has been reportedly said that this year, the birds are re-emerging.

This has altered the local health professionals as they think that West Nile virus can also resurface this summer. Mesa County Health Department Spokeswoman, Kristy Emerson confirmed that the health professionals are worried about the outcomes, as this summer the weather has been extremely warm, thereby, providing a favorable condition for the Culex mosquitoes to grow.

It is known that the female Culex mosquitoes are capable of transferring the West Nile virus to a host.
