Researchers have harnessed a technique known as CRISPR-Cas9 editing in an important and understudied species: the mosquito, Aedes aegypti, which infects hundreds of millions of people annually with the deadly diseases chikungunya, yellow fever, and dengue fever.
Nobody likes getting the flu, but for some people, fluids and rest aren’t enough. A small number...
Ebola has taken its greatest toll on babies. About 90 percent of children under age 1 who caught...
Antibiotic resistance is poised to spread globally among bacteria frequently implicated in respiratory and urinary infections in hospital settings, according to new research at Washington University School of Medicine in St. Louis.
A woman who tested positive for Ebola in Liberia last week is dating a survivor of the disease, a health official said Tuesday, offering a possible explanation for how she became the country's first confirmed case in weeks.
Scientists call for a global strategy for the development of new tuberculosis vaccines.
Study finds vaccination rate far below what's needed to keep virus in check.
Liberians are overcoming their fears of Ebola to volunteer for a vaccine trial.
More than half of the undergraduates at the University of Oregon have not been vaccinated against meningitis, despite the fact that one student has died and five others have been sickened since January.
Could a changing climate and changing environments have an impact on the spread of infectious diseases? At least one zoologist thinks so.
Sierra Leone is planning another three-day, countrywide shutdown later this month to ferret out Ebola cases, remind people how to protect themselves from the disease and control its transmission.
When viruses such as influenza and Ebola jump from one species to another, their ability to cause harm can change dramatically, but research from the University of Cambridge shows that it may be possible to predict the virus’s virulence by looking at how deadly it is in closely-related species.
The largest genetic study of tuberculosis (TB) susceptibility to date has led to a potentially important new insight into how the pathogen manages to evade the immune system.
Dr. Nancy Snyderman said Thursday that she's leaving her job as chief medical editor for NBC News, six months after unleashing public anger for failing to observe a quarantine after covering the Ebola epidemic last fall.
An American healthcare worker who contracted Ebola while volunteering in a Sierra Leone treatment unit arrived safely at the National Institutes of Health's hospital in Maryland, officials announced early Friday.
MIT study finds evidence that a new strain of H1N1 may carry dangerous mutations.
Salk scientists re-engineered the bacterial defense system CRISPR to recognize HIV inside human cells and destroy the virus, offering a potential new therapy.
In the ongoing Ebola outbreak in West Africa, whose death toll is approaching 10,000, little information has been available about how the human immune response unfolds after infection. Researchers have now obtained a first look at the immune responses in four Ebola virus disease survivors who received care at Emory University Hospital in 2014, by closely examining their T cells and B cells during the acute phase of the disease.
Marking the progress in controlling its Ebola outbreak, the Liberian government dismantled a crematorium and removed drums containing the ashes of more than 3,000 Ebola victims cremated during the height of the epidemic, whose last patient was discharged last week.
Three startups are taking advantage of new technology to help patients get treatment for various diseases all over the world.
The United Nations is urging donors, organizations and countries fighting Ebola in West Africa not to give in to complacency as the death toll from the virus climbs toward 10,000.
Mouse studies may lead to development of human therapies.
Future treatments could bind to vulnerable site in viruses causing a variety of diseases.
Sierra Leone's vice president has put himself in quarantine following the death from Ebola of one of his security guards.
Researchers have identified a previously unknown process that many bacteria, including those that cause disease in humans, use to survive. Their discovery could lead to new therapies for bacterial infections like MRSA and tuberculosis that are resistant to current antibiotic treatments.
Contaminated medical instruments are suspected in a "superbug" outbreak at a Los Angeles hospital that has infected at least seven patients, two of whom died. More than 170 others may have been exposed to the antibiotic-resistant bacteria.
New research suggests that this bacterium causes more often causes severe sore throats in young adults than streptococcus — the cause of the much better known strep throat.
Global health organizations said Tuesday that AIDS is now the leading cause of death for adolescents in Africa, and the second leading cause of death among adolescents globally.
