Up to 50% of Europeans died from the plague. Now a new study shows that those who lived had a protective gene mutation they passed on to bolster immunity — but it comes at a cost.

Early fears of an escalating outbreak have not come to pass. Scientists are finding that the virus needs a very particular set of circumstances to spread effectively.

New daily monkeypox cases have been falling, and the CDC says cases are probably going to plateau or decline over the next few weeks.

Throughout the pandemic, some people have avoided catching COVID — despite multiple exposures. Do their immune systems have some type of protection that others are missing?

We crunch the current numbers for high-risk and low-risk groups. We also look at how the risk of monkeypox compares with chances of catching COVID, of being in a fatal car crash and of a shark attack.

A new study suggests that. yes, there are superdodgers. But explaining why they've been able to avoid the virus is a bit complicated.

So sweat doesn't really smell bad at all. But when bacteria eat the sweat — nostrils, look out! Only it turns out that these sweat-eating critters are responsible for a big health benefit.

The U.S. is facing a shortage of the monkeypox vaccine as the outbreak grows rapidly. The White House is pursuing a controversial strategy where each person only gets a fraction of the full dose.

It's basically the same vaccine used against smallpox. Here's how it works — and whether researchers think it's playing a role in the fact that the current outbreak is starting to slow down.

Back in 2017, a doctor in Nigeria noticed how fast a local outbreak of monkeypox was spreading. He tried unsuccessfully to warn the world that Nigeria's outbreak could spread globally.

As the monkeypox outbreak grows, there's a lot of confusion about how the disease spreads. Who is most at risk and how worried should you be?

There's increasing concern that the window of opportunity to contain the monkeypox outbreak in the U.S. has closed. Some experts say it's already too late.

The World Health Organization has declared the monkeypox outbreak an international public health emergency. Scientists say they know where the outbreak began, and who discovered the first known cases.

The testing system set up by the CDC actually deters doctors from ordering a monkeypox test, and many physicians aren't familiar with the disease, resulting in too few tests and little tracking.

Researchers say the U.S. monkeypox outbreak is much larger than the CDC is reporting. Symptomatic people are being denied testing, so it's unclear how many people are infected and spreading the virus.

Scientists in Britain have detected multiple versions of the virus in wastewater. Officials say the risk to the public is extremely low and urge people to ensure their polio vaccines are up to date.

The monkeypox outbreak has grown to more than 800 cases in dozens of countries. Officials say cases are going undetected because the disease looks different than what's described in medical textbooks.

Symptoms that doctors were taught about in medical school are not necessarily indicative of the cases of 2022. It can be much more subtle — and look a lot like other diseases.

Their prediction stemmed from the eradication of smallpox. Here's what they said more than three decades ago — and how it foreshadowed events of 2022.
