2006 - 278
As with most infectious disease in a naïve population, there is a
lovely attack rate curve generated. For Calfornia, we appear to be
past the peak. I'm not sure if we are still decreasing or leveling
2006: Human 51; Horses 4; Dead Birds 24; Mosquito Samples
230; Sentinel Chickens 92; Squirrels - 0
2007: Human 100; Horses 3; Dead Birds 106; Mosquito Samples
194; Sentinel Chickens 50; Squirrels 0
It's interesting that Kern County has had a jump in Human cases while
the rest of the state has leveled off/decreased. I wonder if it is
an increase in circulating virus, an increase in susceptible
population, or/and increase in reporting. At the same time,
denominators are important.
Kern County has a current infection rate of 15.11/100,000 people.
This is only twice the infection rate of Tehama County (7.14/100,000)
which hosted March Crown and three times the rate of Butte County
(5.41/100,000) which I believe is hosting Cynaguan Coronet.
So vaccinate your horses and wear bug spray, but I wouldn't panic yet.

What are the symptoms of WNV?
WNV affects the central nervous system. However, symptoms vary:
Serious Symptoms in a Few People. Less than one percent
(about 1 in 150 people) of individuals infected with WNV will develop
severe illness. The severe symptoms can include high fever, headache,
neck stiffness, stupor, disorientation, coma, tremors, convulsions,
muscle weakness, vision loss, numbness and paralysis. These symptoms
may last several weeks, and neurological effects may be permanent. WN
virus infection can be fatal.
Milder Symptoms in Some People. Up to 20 percent (about 1 in
5) of the people who become infected will display symptoms which can
include fever, headache, body aches, nausea, vomiting, and sometimes
swollen lymph glands or a skin rash on the chest, stomach and back.
Symptoms generally last for just a few days, although even previously
healthy people have been sick for several weeks.
No Symptoms in Most People. Approximately 80 percent of
people (about 4 out of 5) who are infected with WNV will not show any
