After making its debut in the Western Hemisphere recently, the nasty, mosquito-borne illness has now sickened 10 people on St. Martin. Mosquitoes on the island appear to be spreading the virus, which causes a high fever and severe joint pain.
December 17, 2013 Ten years ago Congress approved a $15 billion plan to combat HIV in developing countries. Since then, the global health initiative has funded HIV treatment for nearly 7 million people and prevented hundreds of thousands of babies from getting infected during childbirth.
December 16, 2013 Many soaps and other consumer products have chemicals that are advertised as antibacterial. But there's no evidence that they actually keep people from getting sick, the FDA says. And they may increase the threat of bacteria that are resistant to antibiotics.
December 13, 2013 After being a problem in Africa and southern Asia for decades, chikungunya has made its way to the Caribbean. The mosquito-borne illness attacks the joints, causes fever, headaches and arthritis symptoms. There are no vaccines and treatments for the virus.
December 11, 2013 The billions of dollars spent by governments and foundations to fight malaria are starting to pay off. The death rate from the mosquito-borne disease has dropped by 45 percent worldwide since 2012. Malaria kills more than 600,000 people each year.
December 11, 2013 People who have surgery or are hospitalized for serious illnesses sometimes develop dangerous staph infections. The culprits can be bacteria that were living on people all along. Scientists say the germs thrive in remote parts of the nose that aren't typically tested. Other benign microbes might help keep the bad ones at bay.
December 10, 2013 The vaccine made by Novartis isn't approved for general use in the United States. But the Food and Drug Administration is allowing it on the Princeton campus. The university is offering the vaccine to students and some other people on campus through Thursday.
December 5, 2013 The first in a new class of drugs that can cure the viral infection that is the leading cause of liver failure and liver cancer is poised for a marketing green light from the Food and Drug Administration. More than 3 million Americans have hepatitis C, but most don't know it.
December 4, 2013 A meningitis outbreak at the University of California, Santa Barbara is causing the same kind of illnesses seen earlier at Princeton, but public health officials say a different bacterial strain is to blame. The UCSB health service has given preventive antibiotics to over 700 students as a precaution.
November 26, 2013 A fresh analysis finds that the death toll from the H1N1 swine flu in 2009-10 was severely underestimated. The Americas were hit much harder than Europe or Australia. And the deaths occurred in a much younger population than normally affected by the flu.
November 19, 2013 Princeton University is asking students to get vaccinated with a shot not approved for use in the U.S. in an effort to stop a meningitis outbreak. Meningitis can be deadly, and it spreads in places where people are in close contact, like a dormitory or a prison.
November 19, 2013 It can be tough to stop the plague from spreading in rural Uganda because most villages don't have medical doctors to diagnose the deadly infection. But healers and herbalists are common. A scientist has trained them to detect the illness and refer patients for modern treatment.
November 14, 2013 Lots of women go to the doctor for urinary tract infections, but the standard test does a lousy job of figuring out who could benefit from antibiotics, a study finds. That means that otherwise healthy people can probably skip testing, doctors say, especially if they have had an infection before and know the symptoms.
November 9, 2013 The number of children skipping vaccines has been rising, raising concerns about outbreaks of measles and other infections diseases. A California law designed to encourage parents to get information before deciding about vaccination has been complicated by the governor's addition of an exemption for members of religious groups.
