Near-Zero Risk of HIV Transmission With Low Viral Loads
BRISBANE, Australia – The risk of sexual transmission of HIV with viral loads of less than 1,000 copies per mL was almost zero, according to a meta-analysis and systematic review. In eight studies involving 7,762 serodiscordant couples across 25 countries, there were two cases of possible transmission among patients who had detectable viral loads that […]
More Evidence of Monkeypox Spread Before Symptoms Appear
There could be significant monkeypox transmission before symptoms appear, making it tougher to get infected people into timely quarantine, according to an observational study. An analysis of contact-tracing data from the U.K. Health Security Agency (UKHSA) showed that transmission was spotted up to a maximum of 4 days before symptom onset, and that 53% of […]
A Closer Look at the Monkeypox Outbreak’s Less Than Typical Symptoms
Considering monkeypox in the differential diagnosis is important for early detection and curbing transmission, according to researchers of an observational analysis from England. Among 54 men who have sex with men (MSM) who were diagnosed with monkeypox, all presented with skin lesions, 94% of which were anogenital, while 67% reported fatigue or lethargy and 57% […]
Is HBV the Same as Hepatitis B?
Getting the hepatitis B vaccine is the only way to prevent the disease. Learn about transmission, diagnosis, and treatment Hepatitis B is caused by HBV, or the hepatitis B virus. Most HBV infections resolve within 1-2 months even without active treatment. If the infection lasts longer than 6 months, it can progress to chronic HBV, […]
As Cases Tick Up, Officials Warn on Lack of COVID Funds
With a third of the nation now living in areas of medium to high COVID-19 transmission, White House officials are warning of stalled progress in access to vaccines, treatments, and testing without Congressional funding. Developers are already planning potential vaccines for the fall, but the U.S. government has yet to start negotiating to secure supplies, […]
BPA exposure of the placenta could affect fetal brain development
In a new study, scientists at the University of Missouri demonstrate the direct transmission of bisphenol A (BPA) from a mother to her developing child via the placenta could negatively impact fetal brain development. Cheryl Rosenfeld, a professor of biomedical sciences in the College of Veterinary Medicine, and colleagues propose more attention should be placed […]
Ivermectin Works! (For River Blindness in Nigeria)
Mass drug administration (MDA) with ivermectin appeared to interrupt transmission of onchocerciasis, or river blindness, in several Nigerian states, and may have eliminated it altogether in other parts of the country, researchers said. With a consistent MDA program, transmission of river blindness was “suspected” to be interrupted in four states in southern Nigeria, and transmission […]
