The peak of the flu season could still be several weeks away, federal health officials cautioned Friday.

"We may be on track to break some recent records," said Dr. Anne Schuchat, acting director of the Centers for Disease Control and Prevention. Nearly all states are still reporting widespread flu activity, with less severe reports only coming from Oregon and Hawaii.

"Flu is incredibly difficult to predict and we don't know if we've hit the peak yet," Schuchat said in a call with reporters. "We could still see several more weeks of increased activity."

Health officials in Ohio are working with the CDC to investigate a viral, multi-state outbreak traced to the Ohio-based Petland store chain.

We don't usually think of adorable puppies as disease vectors, but they might actually be making people sick. The Centers for Disease Control and Prevention is investigating a Campylobacter outbreak in people and its link to puppies purchased from a chain of pet stores.

This spring and summer may be a doozy for Lyme disease, at least in parts of the Northeast.

"We're anticipating 2017 to be a particularly risky year for Lyme," says Rick Ostfeld, a disease ecologist at the Cary Institute of Ecosystem Studies in Millbrook, New York.

Ostfeld has been studying the debilitating tick-borne disease for more than 20 years, and has developed an early warning system based on mice. For more on that, check out the piece in our sister blog, Goats and Soda.

Farm animals are increasingly becoming sources of deadly microorganisms like Methicillin-resistant Staphylococcus aureus (MRSA) and that drug-resistant bacteria could be traveling from the farm to your table.

Science Journalist Melinda Wenner Moyer, in an article written for Scientific American, visited three Indiana hog farms last year and witnessed, in two of the cases, crowded barns and special feed laced with antibiotics.

To Test Zika Vaccines, Scientists Need A New Outbreak

Feb 23, 2017

Researchers are eager to test promising vaccines against Zika, the virus that sparked a global health emergency last year.

But uncertainty over whether the Zika epidemic will continue affects researchers' ability to finish testing vaccines. They need locations with an active viral outbreak to conduct large-scale human trials and make sure the vaccine actually protects against disease.

Ten thousand years ago, at the dawn of the agricultural revolution, many of our worst infectious diseases didn't exist.

Here's what changed.

Federal health officials may be about to get greatly enhanced powers to quarantine people, as part of an ongoing effort to stop outbreaks of dangerous contagious diseases.

The new powers are outlined in a set of regulations the Centers for Disease Control and Prevention published late last month to update the agency's quarantine authority for the first time since the 1940s.

A tiny self-propelled drug-delivery device might someday make taking antibiotics safer and more efficient. Think of it as a tiny submarine scooting around inside your stomach, fueled by the acid there.

Oral antibiotics are commonly prescribed life-saving drugs. Once an antibiotic is swallowed, it takes a trip to the stomach, where there's lots of acid. That stomach acid can break chemical bonds in the antibiotic and deactivate it.
