I was hospitalized just last month with dehydration due to West Nile Virus.
The virus carrying mosquitoes came to the U.S. around 1999. It is spreading quickly due to lots of States experiencing warmer winters (like Tennessee, where I live) which does not kill off dormant larvae/virus and/or dry up the creeks and puddles as it usually does.
West Nile virus is spreading West and Northeast a bit more rapidly than the CDC expected. Here is their site on it
http://www.cdc.gov/ncidod/dvbid/westnile/index.htm Here, where I live, there have been 18 cases CONFIRMED so far in humans with hundreds of wild birds and hawks already succumbing to the virus. Of the human cases (in West Tennessee), two have died. One was a young child, the other an elderly person.
Per MY physician, most people that do get bitten by a West Nile-carrying mosquito, won't even know it or will only experience mild, flu-like symptoms three to ten days after being bitten. The bites look NO different and they are not more septic, etc.,
The more fatal complications tend to appear in the elderly, the very young and those individuals with reduced immunities due to illness. However, contracting the sometimes fatal encephalitis (sometimes known as "water on the brain") is very rare.
As with myself, a majority of those even hospitalized with West Nile are treated for the dehydration from nausea, diarrhea and possible vomiting. Watch for neck stiffness and headache though and see your physician even if you think you are being "silly". Better safe than in the hospital!
I was bitten by mosquitoes, dead birds (confirmed with the virus) have been found in our area and at my son's elementary school. Three days later I thought I had the FLU. By the time I went to the doctor I was badly dehydrated - don't make this same mistake.
This virus can also effect your horses, cats, dogs and pet birds. Also, most states and many counties have websites set up for the tracking and prevention of West Nile in your area.
