Four privately owned lemurs contracted human herpes simplex virus 1 (HSV-1) after close contact with people (including a lemur involved in a 'lemur yoga' session) and died from encephalitis; this study marks the first molecular confirmation of HSV-1 in lemurs and highlights the risks of close human–primate interaction in captive settings, urging stricter biosecurity.
UF veterinarians confirmed the first HSV-1 infections in lemurs, with four cases across ring-tailed, black-and-white ruffed, and a Varecia hybrid lemur. All suffered encephalitis and ulcers and died despite treatment. One case may have been linked to a public lemur yoga class, highlighting the risk of human-to-wildlife transmission and the need for stronger biosecurity and minimized direct contact when caring for lemurs. The findings were published in the Journal of Zoo and Wildlife Medicine.
A 74-year-old woman from Wales developed encephalitis caused by herpes simplex virus type 1 (HSV‑1), leading to a 12‑week hospital stay and long‑term brain injury. Doctors note that rapid diagnosis and antiviral treatment within 48 hours can reduce damage, and the family is urging others to watch for early warning signs of encephalitis.
An outbreak of herpes gladiatorum at Edison High School involving wrestlers has raised concerns, with health officials criticizing the school's lack of transparency and cooperation. The district has taken some measures, but communication issues persist, and the health department is considering ending its nursing services due to ongoing conflicts. The situation highlights the importance of prompt and transparent communication in managing public health risks in schools.
Researchers developed a prefusion-specific nanobody that neutralizes HSV-1 and HSV-2 by binding to glycoprotein B, preventing its conformational change necessary for viral fusion, with detailed structural insights provided by cryo-EM.
A mouse study suggests that herpes simplex virus type 1 (HSV-1) may contribute to multiple sclerosis (MS) by damaging myelin, with findings indicating that blocking the MLKL protein can prevent myelin loss and neurological damage, highlighting potential new treatment avenues.
New research reveals that herpes simplex virus type 1 (HSV-1) can alter human DNA within an hour of infection by hijacking the host's cellular machinery, specifically taking control of RNA polymerase II to facilitate rapid viral replication. The study also identifies a potential enzyme, TOP1, that could be targeted to prevent these changes and combat the virus.
Researchers have discovered that herpes simplex virus-1 (HSV-1) hijacks the 3D structure of human DNA to facilitate its replication, but blocking a key enzyme, topoisomerase I, can prevent the virus from replicating, offering a promising new target for antiviral treatments.
A study reveals that herpes simplex virus type 1 (HSV-1) can rapidly reshape human DNA within an hour of infection by altering the 3D genome structure, which helps the virus replicate. Blocking the host enzyme TOP1 can prevent this DNA reorganization, offering a potential target for new treatments against HSV-1, which infects a large portion of the population and remains in the body for life.
Researchers in Spain have discovered that blocking the enzyme topoisomerase I can halt the replication and spread of herpes simplex virus 1 (HSV-1) by preventing it from reshaping human DNA, opening potential pathways for a cure using existing cancer drugs, which could significantly impact the treatment of this widespread and incurable virus.
Researchers discovered that herpes simplex virus-1 (HSV-1) deliberately reshapes the human genome to facilitate its replication, but blocking the enzyme topoisomerase I can prevent this process, offering a potential new treatment strategy.
A study from 1997 suggests a potential link between herpes simplex virus 1 (HSV-1), common in childhood, and the development of Alzheimer's disease, especially in individuals with the ApoE-e4 gene. While most people with HSV-1 do not develop Alzheimer's, the virus's ability to infect the brain and cause inflammation may contribute to the disease in genetically predisposed individuals. More research is needed to confirm this connection and explore preventive strategies.
A study from 1997 suggests a potential link between herpes simplex virus 1 (HSV-1), common in childhood, and the development of Alzheimer's disease, especially in individuals with the ApoE-e4 gene. While most people with HSV-1 do not develop Alzheimer's, the virus's ability to infect the brain and cause inflammation may increase risk in genetically predisposed individuals. More research is needed to confirm this connection and explore preventive strategies.
A recent study suggests a potential association between herpes simplex virus type 1 (HSV-1) and Alzheimer's disease, indicating that HSV-1 infection may increase the risk of developing Alzheimer's, but it does not establish causation. The research highlights the need for further investigation into viral contributions to neurodegenerative diseases, while emphasizing that most HSV-1 carriers do not develop Alzheimer's and that maintaining overall brain health is crucial.
A World Health Organization study reveals that 846 million people globally are infected with genital herpes, a common sexually transmitted infection with no cure. The study highlights the significant prevalence of HSV-1 and HSV-2, with HSV-2 being the primary cause of symptomatic episodes. The infection increases the risk of HIV transmission and poses serious health risks, including neonatal herpes. Despite the economic burden and health challenges, stigma and lack of awareness hinder effective prevention and treatment. WHO calls for urgent development of vaccines and targeted therapies to address this silent epidemic.
