Shingles vaccine is associated with reduction in both postherpetic neuralgia and herpes zoster, but uptake in the US is low A vaccine to prevent shingles may reduce by half the occurrence of this painful skin and nerve infection in older people (aged over 65 years) and may also reduce the rate of a painful complication of shingles, post-herpetic neuralgia, but has a very low uptake (only 4%) in older adults in the United States, according to a study by UK and US researchers published in...
Potential weakness identified in make-up of these deadly agents can immediately yield a sensitive test By screening a library of a billion llama antibodies on live Ebola viruses in the Texas Biomedical Research Institute's highest biocontainment laboratory, scientists in San Antonio have identified a potential weakness in the make-up of these deadly agents that can immediately yield a sensitive test. "Detecting single viral protein components can be challenging, especially at very low...
In a new study, prevention of cellular calcium responses blocked viral entry, and inhibited plaque formation by 90%. Rochester, NY (PRWEB) April 07, 2013 polyDNA has learned that a new paper underlines the status of recent research into the mechanism that allows the herpes virus to invade human cells. (1) The research showed that “calcium release occurs because the viruses activate a critical cell-signaling molecule called Akt at the cell membrane.” (2) Professor Herold said...

Viruses have historically been classified into one of two types – those with an outer lipid-containing envelope and those without an envelope. For the first time, researchers at the University of North Carolina have discovered that hepatitis A virus, a common cause of enterically-transmitted hepatitis, takes on characteristics of both virus types depending on whether it is in a host or in the environment. "The whole universe of virology is divided into two types of viruses – viruses...
Chicken pox, the childhood affliction of earlier generations, has been largely neutralized by the varicella vaccine, according to a new study by the Kaiser Permanente Vaccine Study Center, which appears in the current online issue of Pediatrics. The 14-year study followed 7,585 children who were vaccinated in 1995, when they were 12 to 23 months old, to assess the long-term effectiveness of the vaccine and the impact on the epidemiology of varicella (chicken pox) and herpes zoster...

Interaction between gene and environment predicts disease onset About 90 percent of children with two copies of a common genetic variation and who wheezed when they caught a cold early in life went on to develop asthma by age 6, according to a study to be published March 28 by the New England Journal of Medicine. These children, all from families with a history of asthma or allergies, were nearly four times as likely to develop the disease as those who lacked the genetic variation and...

Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa. From there it was introduced to South America through the slave trade in the 16th century. There...
West Nile virus (WNV) is a virus of the family Flaviviridae. It is part of the Japanese encephalitis antigenic complex of viruses and is found in both tropical and temperate regions. It primarily infects birds but can infect humans, horses, dogs, cats, bats, and other mammals. Humans are generally infected through the bites of mosquitoes and about 90% of West Nile Virus infections are without symptoms. The virion is 45-60 nm and covered with a relatively smooth protein surface. It is...
St. Louis Encephalitis is a disease caused by the Culex mosquito borne St. Louis Encephalitis virus. It is related to Japanese encephalitis virus and is a member of the Flaviviridae subgroup. It mainly affects the United States and occasionally hits Canada and Mexico. The name goes back to 1933 within five weeks in autumn an encephalitis epidemic of explosive proportions broke out in the vicinity of St. Louis, Missouri. Over 1000 cases were reported and the National Institute of Health...
Rotavirus is the most common cause of diarrhea among infants and young children and is one of several viruses that cause the stomach flu. It is in the family Reoviridae and is a genus of double-stranded RNA. Most children have been infected by the age of five. Each infection builds on previous immunity and thus subsequent infections are less severe and adults are rarely affected. The fives species of the virus are referred to as A, B, C, D, and E. Type A, which is the most common, causes more...
Rift Valley Fever (RVF) is a viral zoonosis that causes fever. It is spread through infected mosquitoes. It was first reported in 1915 in Kenya were it infected livestock. Outbreaks occur across sub-Saharan Africa, and in the "˜77-"˜78 outbreak several million people were infected and thousands died during a violent epidemic. In 1998 the virus killed 400 Kenyans and in 2000 an outbreak occurred in Saudi Arabia and Yemen. The virus causes mild illness with fever, headache, myalgia and...
