The flu vaccine may not be very effective this winter, according to U.S. health officials who worry this may lead to more serious illnesses and deaths.
Canadian officials hope an avian flu outbreak has been contained to four quarantined poultry farms in British Columbia. The turkeys and chickens that haven't died from the disease will be euthanized - a total of about 35,000 birds.
Toxoplasma gondii is a common parasite often spread by cats. Most people who are infected in Europe or North America show no symptoms at all, and only a few suffer from encephalitis or ocular toxoplasmosis, which can cause blindness. However, in South America, toxoplasmosis is associated with much more severe symptoms. Read more...
Researchers can now explore viruses, bacteria and components of the human body in more detail than ever before with newly developed software. The researchers demonstrated how the software, called cellPACK, can be used to model viruses such as HIV.
Liberia and Guinea have met a Dec. 1 target for isolating 70 percent of people infected with Ebola and safely burying 70 percent of those who die but Sierra Leone has not, the World Health Organization said Monday.
Two months ago, the WHO launched an ambitious plan to stop the deadly Ebola outbreak in West Africa, aiming to isolate 70 percent of the sick and safely Ebola 70 percent of the victims in the three hardest-hit countries by Dec. 1.
While the turkey you eat on Thursday will bring your stomach happiness and could probably kick-start an afternoon nap, it may also save your life one day.
Raw sprouts are linked to dozens of cases of food poisoning - again. The CDC said 63 people from 10 states concentrated on the East Coast fell ill with salmonella linked to bean sprouts.
Merck & Co., a top creator and seller of vaccines, has joined the fight against Ebola, the often-fatal hemorrhagic virus that's been ravaging parts of West Africa for months.
The next Ebola or the next SARS. Maybe even the next HIV. Even before the Ebola epidemic in West Africa is brought under control, public health officials are girding for the next health disaster.
A plague outbreak has killed 40 people on the island nation of Madagascar, with 119 people diagnosed with the bacterial disease since August. Two people have been diagnosed and one has died in the capital, Antananarivo.
Immunity is a thankless job. Though the army of cells known as the immune system continuously keeps us safe from a barrage of viruses, bacteria and even precancerous cells, we mainly notice it when something goes wrong: “Why did I get the flu this year even though I got vaccinated?” Read more...
They have been a scourge for thousands of years, responsible for the spread of lethal diseases such as malaria and dengue fever, and, much less urgently, a threat to barbecues around the globe. What if there was a way to render humans invisible to mosquitoes?
The spread of Ebola remains "intense" in most of Sierra Leone even as things have improved somewhat in the two other countries hardest hit, the World Health Organization says.
A coalition of companies and aid groups announced plans Tuesday to test experimental drugs and collect blood plasma from Ebola survivors to treat new victims of the disease in West Africa.
A new study from Penn Medicine researchers demonstrated that bed bugs can transmit one of the most prevalent and deadly diseases in the Americas. Read more...
Engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications such as sensors for environmental and medical monitoring.
A top official with the U.N. health agency says few experimental therapies are currently under development that could effectively treat Ebola.
People who carry a particular type of gene have natural resistance against typhoid fever according to new research. The study is the first large-scale, unbiased search for human genes that affect a person’s risk of typhoid.
A novel method of altering a protein in milk to bind with an antiretroviral drug promises to greatly improve treatment for infants and young children suffering from HIV/AIDS, according to new research.
After months of delayed, fragmented responses, the international medical community recognized Ebola as a threat to global health security. Here’s where the situation stands today as well as questions raised and lessons learned.
“Berlin Patient” Timothy Brown was cured of HIV after he received stem cells from a naturally immune patient. His story inspired two companies to try and recreate that natural immunity in HIV patients using stem cells and cutting-edge gene-editing. Now Harvard has joined the race.
The United States Monday opened the first of 17 Ebola treatment units it is building in Liberia. The new clinic opened in Tubmanburg, about 60 kilometers (40 miles) north of the capital, Monrovia.
Bacteria in colonies don’t reproduce sexually and are genetically identical, yet they can prepare in advance for changing environmental conditions. Researchers have shown that bacteria carry out this strategy by producing cells with differing amounts of specific proteins that govern their response to chemical signals.
