Loveland, Colorado (CBS4) - A new case of West Nile virus in a human being confirmed. It is the fifth human case in Colorado this year. One person died in Grand Junction and another was taken to hospital in Pueblo. Two Fort Collins residents have tested positive for the virus. They found after blood donation. Mosquitoes in Indiana and Massachusetts have tested positive for West Nile virus. It is not uncommon for districts to test mosquitoes for West Nile virus, as more and more thoroughly. The mosquitoes that tested positive as carriers for the virus are discussed.
Several counties in Indiana and Massachusetts had mosquitoes test positive. State officials in Massachusetts have low to moderate risk of virus raised in several cities. A moderate risk indicates that the virus is present or the region recently. It is recommended residents to remain on alert, we are still in the peak season for the virus, which will last until September.
It encourages residents to use insect repellent when outside, wear long pants, shirts and socks, keep the windows closed at home and cleaned regularly and cool the water in areas such as bird baths.
According to the National Institutes of Health (NIH), an experimental vaccine that is intended to protect against West Nile virus is to human subjects. During the process, they will be taken into consideration for the safety and ability to generate an immune response in humans, the HydroxVax-001 vaccine. In laboratory experiments, mice were vaccinated, adding lethal doses of West Nile virus free.
Researchers at the School of Medicine at Duke in Durham, North Carolina will be responsible for the clinical trial phase 1. There is a placebo-controlled, total randomized double-blind experience. At the end of the test, 50 healthy men and women between 18 and 50 years were enrolled.
There are three groups of volunteers are assigned to be random. The first group consists of 10 volunteers who received placebo. Another group of 20 volunteers received a vaccine of low dose (1 mcg) and the last group of volunteers with a higher dose (4 mcg) for. Participants gave their dose at the first and 29th of the process, administered by intramuscular injection. The researchers then continue for 14 months.
Portland, Oregon Health & Science University researchers developed the vaccine, which uses a deadly virus that does not cause infection of West Nile virus. Dr Mark Slifka OHSU is a principal investigator and he led the team that produces the active vaccine a method of hydrogen peroxide, which keeps the virus inactive and keys simultaneously dissolves the virus surface structure, is an immune response.
According to the researchers, the use of an inactive virus means that anyone can use, including vulnerable groups such as people with weakened immune systems and the elderly.
West Nile virus can be found in and spread by mosquitoes in many parts of the world. It was discovered in the U.S. in 1999 in the city of New York the rest of the nation, first, then. Although, most people never symptoms of infection feel, you can have five mild flu symptoms such as fever, muscle pain, headache, nausea and vomiting.
The virus can be fatal, with experience in 150 cases, more serious complications such as meningitis (inflammation of the lining of the spinal cord and brain) and encephalitis (brain inflammation). Infections usually begin in late spring or early summer continues to fall. In 2014, there were about 100 deaths from West Nile reported in the U.S.
