A new study published today in Science reveals a close correlation between species in the wildlife trade and animals that are known to have passed pathogens on to humans. There's a strong link, says Jerome Gippet, an ecologist at the University of Fribourg in Switzerland.

I am open-minded; I believe in integrative practices, and I agree that the medical establishment can be arrogant and unduly influenced by the pharmaceutical industry, which now funds so much of medical research. But I fully understand Scherer's frustration with his interminable discussions with Kennedy about scientific articles.

We have a large reservoir of people with (latent tuberculosis infections), and they should be tested and treated. But they're not, for a variety of reasons. This statement from Dr. Amit Chitnis, tuberculosis controller for the Alameda County Public Health Department, highlights the critical gap in TB management where infected individuals remain untreated despite the availability of interventions.

DNA variants near a gene called MSRB3 - which is important for hearing in humans - could determine whether a dog's ears are pendulous like a basset hound's or stubby like a rottweiler's. Researchers analysed the genomes of thousands of canines and found that small, single-letter changes to DNA in a region of the genome near MSRB3 could boost the gene's activity. The boost can increase the rate at which ear cells proliferate, resulting in longer ears.

In a study published in Science Advances, researchers in China fed Aedes aegypti mosquitoes blood that contained either a vaccine against Nipah virus or the rabies virus. The viruses, contained in the vaccines, replicated inside the insects and reached their salivary glands, allowing them to pass on the vaccine when feeding on bats or when the bats ate the insects.

Being overweight doesn't just make people more susceptible to chronic illnesses such as heart disease and diabetesit might also increase their risk of severe influenza and other infections, a new study confirms. The study, published today in the Lancet, suggests that people with obesity may be more susceptible to death and hospitalization from a variety of infections caused by viruses, fungi, parasites and bacteria.

Public health consultant Dr Ross Keat said supporting people earlier to make small preventative changes would make "a big difference later on". Some 3,500 people in the north of the island within that age bracket are eligible for the checks. The checks will be carried out by two pre-existing nurses that support GP staff and would not replace GP appointments, Keat explained, adding that the cost would be minimal and absorbed by Ramsey Group Practice.

If you feel like everyone you know is dealing with a cough, cold and runny nose, it's not in your head. Multiple viruses, not just the flu, are currently circulating near season-high levels in the San Francisco Bay Area, according to wastewater data. Flu tests show seasonal influenza activity continues to be elevated in the region, although it's down from the season-high peak at the end of December, according to the California Department of Public Health.

Flu season is showing no signs of slowing down in California, with every region experiencing either high or very high levels of flu. In the Bay Area, the number of people testing positive for the virus has hit a new seasonal high, with 18.99% of flu tests coming back positive through Jan. 31, according to the latest numbers from the California Department of Public Health.

The San Francisco Department of Public Health said in a news release that among the 1,261 students and staff at the high school, 219 people, or about 17%, tested positive for TB. Subsequently, 204 of those people had confirmed cases of latent TB. The number is a major increase from the 50 latent cases detected by the end of January as testing was ramping up among the school's students and staff.

"What we've identified here could help improve adherence to vaccination quicker if we target the right people," he says.
