A study has deemed that condoms use is associated with moderate protection against herpes simplex virus 2.
Herpes simplex virus 2 (HSV-2) typically causes genital herpes, a chronic, life-long, viral infection.
HIV Transmission Not Helped By Herpes Drug
An international clinical trial has shown that a widely used drug for herpes simplex virus-2 (HSV-2) does not reduce the risk of HIV transmission when taken by people infected with both HIV and HSV-2.

For the study, Emily T. Martin, M.P.H., Ph.D., of Children's Hospital Research Institute and the University of Washington, Seattle, and colleagues analyzed data from six HSV-2 studies to assess the effectiveness of condom use in preventing the virus.
The studies included three candidate HSV-2 vaccine studies, an HSV-2 drug study, an observational sexually transmitted infection (STI) incidence study and a behavioral STI intervention study.
Herpes Infection and Corneal Transplants
Two studies that may influence clinical treatment of serious eye conditions appear in the July issue of Ophthalmology, the journal of the American Academy of Ophthalmology.

More than 66 percent of those who took part in the six studies were male, 60.4 percent were white, 94.1 percent were heterosexual and most reported no prior STIs.

"Consistent condom users [used 100 percent of the time] had a 30 percent lower risk of HSV-2 acquisition compared with those who never used condoms. Risk of HSV-2 acquisition decreased by 7 percent for every additional 25 percent of the time that condoms were used during anal or vaginal sex," the authors said.
Antiherpes Drug a Doubleedged Sword for HIV Patients
A new study has revealed that the anti-herpes drug acyclovir can slow down HIV infection, but with the risk that treated cells may promote the emergence of multi-drug resistant HIV variants.

"Based on findings of this large analysis using all available prospective data, condom use should continue to be recommended to both men and women for reducing the risk of HSV-2 acquisition," the authors said.
"Although the magnitude of the protective effect was not as large as has been observed with other STIs, a 30 percent reduction in HSV-2 incidence can have a substantial benefit for individuals as well as a public health impact at the population level," they added.
The report was based on pooled analysis of data from previous studies in the July 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
