There's been a new outbreak of Ebola in the Democratic Republic of the Congo. Eleven people have been sickened by the disease, and one has died. Here are some things you might not have known about Ebola.

1. THERE'S MORE THAN ONE KIND OF EBOLAVIRUS.

Five species of Ebolavirus have been identified, each named after the place they sprung up: Ebola (formerly Zaire), Bundibugyo, Sudan, Taï Forest, and Reston. All but one—Reston—arose in Africa. The Reston subtype is named after a town in Virginia where an outbreak occurred in 1989, followed by incidents in Texas and Pennsylvania; all three were tied to infected monkeys exported by a single facility in the Philippines. All Ebolavirus species affect people and nonhuman primates—monkeys, gorillas, and chimpanzees—but Reston doesn't cause detectable disease in humans.

2. EBOLA HIJACKS THE IMMUNE SYSTEM.

Researchers are finding out just how clever Ebola is. One key to its lethal success is the stealth way it shuts down immune system defenses, the same way an air force will disable air defenses before sending in the bombers. Ebola obstructs parts of an immune system that are activated by molecules called interferons. These interferons have a vital role in fighting Ebola, usually with scorched-earth tactics such as apoptosis, or cell self-destruction. A 2014 study found that Ebola disables signals the cells use to defend against its attack using a protein called VP24, which binds to a specific protein that takes signaling molecules in and out a cell's nucleus. Blocked from communication, the cell can't call for help or get the order to self-destruct. The virus then hijacks the cell, uses it to make more viruses, and spreads them to more cells. It also produces ebolavirus glycoprotein, which binds to cells inside blood vessels, increasing their permeability and leading to leakage. This contributes to the catastrophic bleeding characteristic of late-stage Ebola infection.

3. BATS ARE THOUGHT TO BE THE KEY HOSTS OF EBOLA.

Scientists believe that Ebola's natural host species, or "reservoir hosts," are bats. Infected bats can pass the virus to other mammals, including rats, primates, and us. No one is sure how people first became exposed to Ebola, but the best guess is that monkeys were the conduit. Local hunters in Africa likely became infected while butchering the animals. Anyone who became sick likely infected their family and, if hospitalized in an unsanitary facility, other patients. When the illness spreads from person to person, it does so through direct contact with the bodily fluids of someone who is sick with or has died from Ebola.

4. MEDICAL DETECTIVE WORK IS THE ONLY WAY TO STOP AN EBOLA OUTBREAK.

It takes the investigative skill of a homicide detective to stop an outbreak. Professionals call it contact tracing. Here's how it works: Ebola victim A is isolated and interviewed. Anyone who had close contact with A is put into quarantine for 21 days. If they exhibit no symptoms, they're free to go when the three weeks are up. If they come down with Ebola, they become victim B, and another contact trace begins. If the investigators miss anyone, the outbreak will continue.

5. HAVING MALARIA AND EBOLA AT THE SAME TIME MAY HELP PEOPLE SURVIVE.

Researchers analyzing the the 2014 outbreak of Ebola in West Africa made a surprising finding: patients who had an active malaria parasite infection were actually more likely to survive the Ebola virus, and by a significant degree. While just over half (52 percent) of Ebola patients not infected with malaria survived, those co-infected with malaria had a survival rate of 72 to 83 percent, depending on their ages and the amount of Ebola virus in their blood. The researchers aren't yet sure why, but the prevailing theory is that malaria somehow modifies the immune response to Ebola by toning down a phenomenon called the "cytokine storm"—the body's own response to an Ebola infection, which inadvertently kills the host while attempting to eliminate the pathogen. If malaria can dampen this response, infected patients may have a better chance of surviving.

6. IF YOU'RE A SCIENTIST, YOU CAN ORDER EBOLA ONLINE.

We do not yet have a vaccine or antiviral drug to treat Ebola, but many scientists are working to find one. One source is the National Institute of Allergy and Infectious Diseases (NIAID)'s BEI Resources, which gives research facilities access to microbiological materials called reagents that can help them develop diagnostics and vaccines for emerging diseases, including Ebola. Scientists must be registered with BEI to request materials. Reagents are not active viruses, so they can't spread; on the biosafety level, or BSL, scale—which ranks the severity of infectious disease and sets required safety protocols for working with them in a lab—the Ebola-related reagents are considered BLS 1—the lowest risk. (Live Ebola virus is BLS 4—the highest.) Ordering is limited to one Ebola-related reagent at a time, and can be ordered only twice per year.

12 Creative Ways to Spend Your FSA Money Before the Deadline

If you have a Flexible Spending Account (FSA), chances are, time is running out for you to use that cash. Depending on your employer’s rules, if you don’t spend your FSA money by the end of the grace period, you potentially lose some of it. Lost cash is never a good thing.

For those unfamiliar, an FSA is an employer-sponsored spending account. You deposit pre-tax dollars into the account, and you can spend that money on a number of health care expenses. It’s kind of like a Health Savings Account (HSA), but with a few big differences—namely, your HSA funds roll over from year to year, so there’s no deadline to spend it all. With an FSA, though, most of your funds expire at the end of the year. Bummer.

The good news is: The law allows employers to roll $500 over into the new year and also offer a grace period of up to two and a half months to use that cash (March 15). Depending on your employer, you might not even have that long, though. The deadline is fast approaching for many account holders, so if you have to use your FSA money soon, here are a handful of creative ways to spend it.

1. Buy some new shades.

Head to the optometrist, get an eye prescription, then use your FSA funds to buy some new specs or shades. Contact lenses and solution are also covered.

You can also buy reading glasses with your FSA money, and you don’t even need a prescription.

2. Try acupuncture.

Scientists are divided on the efficacy of acupuncture, but some studies show it’s useful for treating chronic pain, arthritis, and even depression. If you’ve been curious about the treatment, now's a good time to try it: Your FSA money will cover acupuncture sessions in some cases. You can even buy an acupressure mat without a prescription.

If you’d rather go to a chiropractor, your FSA funds cover those visits, too.

3. Stock up on staples.

If you’re running low on standard over-the-counter meds, good news: Most of them are FSA-eligible. This includes headache medicine, pain relievers, antacids, heartburn meds, and anything else your heart (or other parts of your body) desires.

There’s one big caveat, though: Most of these require a prescription in order to be eligible, so you may have to make an appointment with your doctor first. The FSA store tells you which over-the-counter items require a prescription.

4. Treat your feet.

Give your feet a break with a pair of massaging gel shoe inserts. They’re FSA-eligible, along with a few other foot care products, including arch braces, toe cushions, and callus trimmers.

In some cases, foot massagers or circulators may be covered, too. For example, here’s one that’s available via the FSA store, no prescription necessary.

5. Get clear skin.

Yep—acne treatments, toner, and other skin care products are all eligible for FSA spending. Again, most of these require a prescription for reimbursement, but don’t let that deter you. Your doctor is familiar with the rules and you shouldn’t have trouble getting a prescription. And, as WageWorks points out, your prescription also lasts for a year. Check the rules of your FSA plan to see if you need a separate prescription for each item, or if you can include multiple products or drug categories on a single prescription.

While we’re on the topic of faces, lip balm is another great way to spend your FSA funds—and you don’t need a prescription for that. There’s also no prescription necessary for this vibrating face massager.

6. Fill your medicine cabinet.

If your medicine cabinet is getting bare, or you don’t have one to begin with, stock it with a handful of FSA-eligible items. Here are some items that don’t require a prescription:

You can also stock up on first aid kits. You don’t need a prescription to buy those, and many of them come with pain relievers and other medicine.

7. Make sure you’re covered in the bedroom.

Condoms are FSA-eligible, and so are pregnancy tests, monitors, and fertility kits. Female contraceptives are also covered when you have a prescription.

8. Prepare for your upcoming vacation.

If you have a vacation planned this year, use your FSA money to stock up on trip essentials. For example:

9. Get a better night’s sleep.

If you have trouble sleeping, sleep aids are eligible, though you’ll need a prescription. If you want to try a sleep mask, many of them are eligible without a prescription. For example, there’s this relaxing sleep mask and this thermal eye mask.

For those nights you’re sleeping off a cold or flu, a vaporizer can make a big difference, and those are eligible, too (no prescription required). Bed warmers like this one are often covered, too.

Your FSA funds likely cover more than you realize, so if you have to use them up by the deadline, get creative. This list should help you get started, and many drugstores will tell you which items are FSA-eligible when you shop online.

10. Go to the dentist.

While basics like toothpaste and cosmetic procedures like whitening treatments aren’t FSA eligible, most of the expenses you incur at your dentist’s office are. That includes co-pays and deductibles as well as fees for cleanings, x-rays, fillings, and even the cost of braces. There are also some products you can buy over-the-counter without ever visiting the dentist. Some mouthguards that prevent you from grinding your teeth at night are eligible, as are cleaning solutions for retainers and dentures.

11. Try some new gadgets.

If you still have some extra cash to burn, it’s a great time to try some expensive high-tech devices that you’ve been curious about but might not otherwise want to splurge on. The list includes light therapy treatments for acne, vibrating nausea relief bands, electrical stimulation devices for chronic pain, cloud-connected stethoscopes, and smart thermometers.

12. Head to Amazon.

There are plenty of FSA-eligible items available on Amazon, including items for foot health, cold and allergy medication, eye care, and first-aid kits. Find out more details on how to spend your FSA money on Amazon here.

Doctor’s 60-Second Trick Makes Any Face Mask Fit Better

As face masks have become part of daily life, people have come up with innovative ways to make them more comfortable and effective. There are tricks for masking up without hurting your ears, fogging up your glasses, or breaking out. This new tip from Olivia Cuid, M.D. could be the key to making large masks fit better around your face.

As Self reports, this hack takes 60 seconds or less and works on both disposable masks or cloth masks with ear loops. To prevent the sides of your mask from popping out—making it easier for microbes to travel in and out of the space behind it—tie both ear loops into a knot. The closer the knot is to the side of the mask, the tighter the mask will fit on your face.

Once the loops are secure, open up the mask and look for gaps where the knots meet the fabric. Close these holes by tucking them behind the loops. Now, when you wear your mask, the fabric should fit snugly against your face. You can watch Dr. Cuid demonstrate the trick in the TikTok below.
