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.
The Ebola virus remains viable for at least seven days after death in non-human primates. A new study, published in Emerging Infectious Diseases, suggests that Ebola transmission from deceased individuals may be possible for an extended period of time after death, underscoring the importance of using safe practices for handling corpses.
This winter's nasty flu season has peaked and is clearly retreating, a new government report shows.
Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus.
Microbes, small and ancient life forms, play a key role in maintaining life on Earth. As has often been pointed out, without microbes, we’d die—without us, most microbes would get along just fine.
For decades, scientists have thought the bacteria that cause the bubonic plague hijack host cells at the site of a fleabite and are then taken to the lymph nodes, where the bacteria multiply and trigger severe disease. But UNC School of Medicine researchers discovered that this accepted theory is off base. The bacteria do not use host cells; they traffic to lymph nodes on their own and not in great numbers.
Ebola has claimed nearly 9,000 lives in West Africa over the past year, although new infections have dropped dramatically in recent months.
Researchers have revealed new insights into possible ways to vaccinate people to generate potent antibodies of the type that are predicted to offer protection against diverse strains of the highly mutable HIV.
Several state legislatures are debating vaccine-related measures as dozens of people have fallen ill from a measles outbreak that started at Disneyland in December and spread beyond the theme park.
In 2008, the World Health Organization announced a global effort to eradicate malaria, which kills about 800,000 people every year. As part of that goal, scientists are trying to develop new drugs that target the malaria parasite during the stage when it infects the human liver, which is crucial because some strains of malaria can lie dormant in the liver for several years before flaring up.
Since December, more than 100 people in 14 states have been infected with measles in an outbreak traced to Disneyland, Melissa Stockwell, MD, MPH, assistant professor of pediatrics and of population & family health, has spoken out to debunk seven myths about the measles vaccine.
The largest U.S. measles outbreak in recent history isn't the one that started in December at Disneyland. It happened months earlier in Ohio's Amish country, where 383 people fell ill after unvaccinated Amish missionaries traveled to the Philippines and returned with the virus.
The drop-off in Ebola infections is good news for Liberia, but it means there are not enough sick people to take part in the study.
Federal health officials faced tough questions from lawmakers Tuesday about why they didn't take steps to produce a better flu vaccine as it became clear that this year's version wasn't going to offer much protection.
A team of international scientists has discovered a new mechanism by which immune cells in the skin function act as the body's 'border control', revealing how these cells sense whether lipid or fat-like molecules might indicate the presence of foreign invaders.
President Obama held a press conference revealing new details surrounding the Precision Medicine initiative he announced during the State of The Union.
Researchers have begun to appreciate the importance of copy number variation when considering the connections between DNA and disease.
A measles outbreak in Arizona that originated at California's Disney parks is at risk of increasing dramatically in size as health officials keep tabs on 1,000 people, including nearly 200 children who could have been exposed at a Phoenix-area medical center.
The U.N. health agency said the three most affected countries - Guinea, Sierra Leone and Liberia - have reported fewer than 100 cases in the past week, for the first time since June.
After undergoing surgery to remove diseased sections of the colon, up to 30 percent of patients experience leakage from their sutures, which can cause life-threatening complications.
Killer T cells are one of the body's main lines of defense against pathogens.
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
The World Health Organization has proposed reforms that could overhaul its structure after botching the response to the biggest-ever Ebola outbreak.
