A 1998 study predicts that global warming will increase the potential transmission of dengue fever in temperate regions. The researchers used computer models to simulate climate change and found that a relatively small temperature rise can lead to an increase in epidemic potential, allowing for more efficient virus spread.
Rising global temperatures could lead to the expansion of dengue fever's geographic range into temperate regions. The mosquito Aedes aegypti's larval size and adult frequency will increase with warmer temperatures, boosting disease transmission.
The University of North Carolina at Chapel Hill School of Medicine is establishing a unique clinical trials unit to develop and test new therapies and vaccines for sexually transmitted diseases. The unit will focus on addressing major problems worldwide, including syphilis and gonorrhea, and will be the first of its kind in the US.
Researchers discovered a strain of hepatitis E virus in pigs that is similar to the human strain, but not causative of disease. The finding may contribute to the development of a vaccine and improve our understanding of the virus's transmission and prevalence.
Researchers found that treating co-infections with sexually transmitted diseases (STDs) significantly reduces the amount of virus shed in semen, making transmission less likely. The study suggests widespread STD screening and therapy could be a crucial step in combating HIV/AIDS globally.
A collaborative study between the US and Russia aims to uncover the causes of Hepatitis C, a prevalent liver disease. The project will collect blood samples and questionnaires from over 4,000 individuals across New Mexico and Chelyabinsk-70, with results expected to shed new light on the virus.
Human granulocytic ehrlichiosis (HGE) found in white-tailed deer and black bears, with 56% of Midwestern patients hospitalized due to severe symptoms. Early detection is crucial for treatment with a special antibiotic, which can cure the infection in 24-48 hours.
Hepatitis A virus is the most severe foodborne viral disease, causing liver damage and debility. Viruses are transmitted through direct or indirect contamination of foods with human feces, highlighting the importance of good hygiene practices in preventing transmission.
Researchers identified three key factors that significantly boost the spread of HIV: having other STDs, multiple sexual relationships, and sex with people newly infected. Increasing STD detection and treatment, and focusing on early HIV infections can help curb the epidemic.
The Pediatric ACTG Protocol 185 clinical trial was stopped early due to an unexpectedly low rate of infant HIV infection, making it impossible to compare treatment outcomes. The study confirmed the effectiveness of AZT in reducing mother-to-child HIV transmission, extending its benefits to women with more advanced disease and previous ...
Researchers found that viral load in semen increases with progression of the disease in most patients. Using antiviral therapy, they were able to reduce viral load in semen to undetectable levels in six patients.
Recent advances in HIV research reveal the critical role of host factors in determining disease progression and replication rates. Key discoveries include the regulation of HIV replication by immune response molecules and the activation of the immune system by the virus.
Researchers analyzed data from 958 individuals and found equal rates of chlamydial infection in men and women. The study suggests that diagnostic tests using PCR or LCR may be effective in controlling the spread of Chlamydia.
A recent analysis of ACTG 076 data found that the risk of perinatal transmission of HIV can occur even when a woman has little or no detectable virus in her blood. Offering AZT therapy to all pregnant HIV-infected women is crucial, regardless of their stage of disease.
A study conducted by the University of Washington found that HIV transmission can occur even among individuals with few sexual partners, and that oral sex is a common route of transmission among gay men. Despite warnings from health experts, unprotected oral sex may not be as safe as previously thought.
