At least 90 people have been hospitalized from an anthrax outbreak in Russia, including 50 children. Eight are confirmed as infected with anthrax. Doctors believe at least 6 patients have the more virulent intestinal form of the disease, which killed one boy, age 12. Authorities say it's the first fatal anthrax outbreak in Russia in more than 75 years.

Approximately 350,000 people in the US are diagnosed with gonorrhea each year. According to the CDC, it may soon be untreatable. Currently, the sexually-transmitted disease, not-so-fondly known as The Clap or The Drip, is treated with two antibiotics, azithromycin and ceftriaxone. Data is currently showing a rise in gonorrhea samples that are resistant to those drugs.
Companies are developing new antibiotics but could be "years away," says CDC medical epidemiologist Robert D. Kirkcaldy.
"We think … it’s a matter of when and not if with resistance,” he says. “This bug is so smart and can mutate so rapidly.”

The Centers for Disease Control and Infection reported the first confirmed case of Zika transmitted from a woman to a man during sex. Previously, they thought that the disease was only likely to be sexually-transmitted from a male to female or male to male. The CDC will soon update their advisory "for sexually active people in which the couple is not pregnant or concerned about pregnancy and for people who want to reduce personal risk of Zika infection through sex."

A non-pregnant woman in her 20s had unprotected vaginal sex with a male partner on the day she returned from travel to a country where Zika is circulating. The next day, she came down with Zika-like symptoms, including fever, rash, fatigue and muscle pain, along with numbness and tingling in her fingers and toes. On day three, she visited her primary care doctor, who took blood and urine samples, and sent them off to the NYC health department. Both tested positive for the virus.
On day seven after intercourse, her male partner, also in his 20s, began to show the same typical signs of Zika, such as fever, rash, joint pain and red eyes, despite the fact that he had not traveled outside the United States for more than a year...
While this is the first documented case of female to male sexual transmission, it's not the first clue that the Zika virus might be hiding in the female genital tract. A case report published this week in The Lancet Infectious Diseases journal tells the story of a 27-year old Guadeloupean woman who came down with Zika in May.
A woman in San Diego, CA is reported to have contracted the Zika virus through sexual transmission.

People between the ages of 15-30 are more likely to die from external causes than any other reason. The 60s, 70s, and 80s are cancer years. If you've made it that far, your failing heart is most likely to kill you. Nathan Yau created this stacked area graph that "shows how cause of death varies across sex and race, based on mortality data from 2005 through 2014. Select a group to see the changes. Select causes to see them individually." Read the rest
Out of everyone who ever existed, who has done the most good for humanity? It's a difficult question.
A 21-year-old California woman died from an amoeba that settles in the brain and destroys its tissue. The disease she contracted is called primary amoebic meningoencephalitis (PAM). It is rare, with only zero to eight cases reported a year, says Inyo Public Health officer Dr. Richard Johnson. But it is almost 100 percent fatal.
Humans are infected by the amoeba, Naegleria fowleri, when swimming or diving in fresh, warm water. The amoeba then migrates through the nose and skull, where it reaches the brain and begins to destroy brain tissue.
"I advise people to be cautious when using untreated hot springs in the Sierras," Dr. Johnson said, "The best way to do that is to keep your head above water."

Up to 75 scientists who work at a US Centers for Disease Control and Prevention biosecurity lab in Atlanta may have been exposed to anthrax, because researchers there did not follow procedures for inactivating the deadly and highly contagious bacteria.

More than 100 people reportedly fell ill with food poisoning while attending a high-profile Food Safety Summit in Baltimore, Maryland. The 1,300 attendees included representatives from the Food and Drug Administation, Centers for Disease Control and Prevention, Tyson, McDonald's, and many more agencies and food companies.

Narcolepsy is an autoimmune disease
— a finding that helps explain why the 2009 swine flu (and the vaccine used to prevent it) was correlated with increased cases of narcolepsy. Read the rest
I'm 38 weeks pregnant now. Two weeks ago, my husband and I both got Tdap vaccines — tetanus, diphtheria, and pertussis. This despite the fact that we've both gotten Tdaps relatively recently, within the last six years, thanks to a home renovation lifestyle that involves regular exposure to rusty nails.
So why re-up on the Tdap before the birth of our baby? It's all about the pertussis. Also called whooping cough, pertussis is particularly hard on infants. Pre-vaccine, it killed 4000 Americans every year, and most of them were new babies — and infections are on the rise in this country, so there's actually a reasonable risk of a newborn coming into contact with the bacteria that causes pertussis. But the larger problem is with the pertussis vaccine, itself. It doesn't have the staying power it once did. A little over 20 years ago, we switched the formulation for pertussis vaccines. There were good reasons for doing that — the "new" formula has fewer side effects. But it also doesn't seem to protect people as well for as long. In fact, the protection starts to wear off within a year of vaccination. Read the rest
At Matter, physical therapy professor Eric Robertson writes about a very rare condition called rhabdomyolysis — it's what happens when chronically overworked muscle cells rupture and overload your kidneys with massive amounts of protein. The results are painful, reasonably disgusting, and potentially deadly. Rhabdomyolysis used to be something you only had to worry about if you were, say, part of an elite military squad or a professional athlete. But as more average folks have gotten into elite physical training regimens through programs like CrossFit, the profile of people damaged by rhabdomyolysis is changing
. Training like a bad-ass can bring along some of the physical risks of being a bad-ass. Read the rest
Valley fever is a respiratory disease that can cause flu-like symptoms, rashes, and (sometimes) chronic lung problems. It's caused by a fungus that lives in dry soil, essentially hibernating for years until it's reinvigorated by moisture. Valley fever is best known for infecting prisoners in the American southwest, but it's also an occupational hazard of archaeologists
... who spend most of their lives sifting through the soils where the fungus lives. Read the rest
