Canine Flu is On the Rise: Here's What You Should Know

It's been eight years since the World Health Organization announced the end of the swine flu pandemic, and now the condition is back in the news for infecting a different type of host. As Live Science reports, the H1N1 virus is mixing with canine flu to create new strains that could potentially spread to people.

Dog flu has been around for a couple of decades, but the two main canine strains, H3N8 and H3N2, have never been contracted by humans. According to a new study published in mBio, some dogs in the Guangxi region of China were found carrying H1N1, the flu strain at the root of the swine flu outbreak. Researchers also discovered three entirely new flu strains that were a combination of H1N1 and regular dog flu viruses.

The unrecognized flu strains are the most troubling discovery. As the flu travels between species, it mingles with viruses that are already there, creating a level of genetic diversity that leaves our immune systems, which are best equipped to fight strains they've already been exposed to, vulnerable. The swine flu epidemic of 2009 started in a similar way, when H1N1 jumped from birds to pigs, and eventually to people.

But the new report isn't a reason to banish your pet to the doghouse next time she seems under the weather. The virus samples were collected from dogs in China between 2013 and 2015, and in the years since, zero humans have caught influenza from dogs (though dog flu has started spreading to cats). If the virus continues mutating to the point where it can infect humans, both the CDC and U.S. Department of Agriculture will take action. But for now, the CDC states that canine flu viruses "pose a low threat to people."

Canine flu may not be dangerous to humans yet, but it can still be stressful for dog owners if their pet comes down with a case. Ask your vet about getting your dog vaccinated, and if you see your dog coughing, sneezing, and acting less energetic than usual, make an appointment to get him checked out as soon as possible. If he does have the flu, he can be treated with plenty of rest and hydration.

Why Does Hand Sanitizer Have an Expiration Date?

The coronavirus pandemic has turned hand sanitizer from something that was once idly tossed into cars and drawers into a bit of a national obsession. Shortages persist, and people are trying to make their own, often to little avail. (DIY sanitizer may not be sterile or contain the proper concentration of ingredients.)

If you do manage to get your hands on a bottle of Purell or other name-brand sanitizer, you may notice it typically has an expiration date. Can it really go “bad” and be rendered less effective?

The short answer: yes. Hand sanitizer is typically made up of at least 60 percent alcohol, which is enough to provide germicidal benefit when applied to your hands. According to Insider, that crucial percentage of alcohol can be affected over time once it begins to evaporate after the bottle has been opened. As the volume is reduced, so is the effectiveness of the solution.

Though there’s no hard rule on how long it takes a bottle of sanitizer to lose alcohol content, manufacturers usually set the expiration date three years from the time of production. (Because the product is regulated by the Food and Drug Administration, it has to have an expiration date.)

Let's assume you’ve found a bottle of old and forgotten sanitizer in your house somewhere. It expired in 2018. Should you still use it? It’s not ideal, but if you have no other options, even a reduced amount of alcohol will still have some germ-fighting effectiveness. If it’s never been opened, you’re in better shape, as more of the alcohol will have remained.

Remember that sanitizer of any potency is best left to times when soap and water isn’t available. Consider it a bridge until you’re able to get your hands under a faucet. There’s no substitution for a good scrub.

7 Quick Tips for Disinfecting Your Home the Smart Way

With many people spending more time—or virtually all of their time—indoors, it’s natural for thoughts to turn to how to best clean surfaces that might help minimize the risk of spreading illness. Although researchers believe respiratory droplets are the primary way coronavirus is transmitted, preliminary data, which is not yet peer-reviewed, suggests the virus may remain on some surfaces for hours or days.

While scrubbing isn't a complex process, there are nonetheless some areas of your home you might be neglecting. Here’s how to best approach a household scrub, as well as identify and disinfect some common germ hot spots.

1. Pay attention to high-touch surfaces and clean them frequently.

High-touch surfaces are exactly what they sound like: Areas in the home that get handled and touched regularly. Think doorknobs, light switches, appliance handles, toilet handles, faucets, and remotes. And don’t forget laptops, keyboards, desks, and phones.

2. Don't just do a quick wipe down. Get the entire surface.

Taking a disinfecting wipe to the keyhole of a doorknob isn’t going to do you much good—it's important to really scrub all high-touch surfaces. Make sure you get every available surface area, including the plate behind the knob where fingers and hands often brush against it. When cleaning remotes, make sure you don't just scrub the buttons, but the space between them as well.

3. You can use soap and water.

While products claiming to kill 99.9 percent of germs are best in this scenario, there's another option if you're having a hard time tracking down those supplies—simply mix some dish soap in water. It won’t kill organisms, but it can remove them from the surface. (And while soap and water can work for high-touch surfaces throughout the home, you shouldn't use the solution on electronics like your remote or keyboard.)

If you’re looking to kill germs, diluted bleach (four teaspoons to one quart of water) and 70 percent alcohol solutions work well. But it's important to note that bleach and other cleaners can harm certain surfaces. So be sure to do your research and make sure the product you're using won't cause any damage before you start scrubbing.

4. Take laundry precautions.

If you’re trying to be extra-vigilant about the spread of germs in the house, you should consider washing clothes at the highest possible temperature and disinfecting laundry bins. It’s also advisable to use disposable laundry bags.

5. Remove your shoes before entering the house.

This step is more preventative, but it’s a simple way to keep from tracking in contaminants. Remove your shoes before going inside and leave them near the door. It's also a good idea to clean floor surfaces with disinfecting mop cloths, but be sure anything you use is safe for the finished surface. Cleaners like bleach can discolor certain materials.

6. Don't forget to clean your car.

Even people vigilant about cleaning their home can neglect their car interior. Since you’re constantly touching virtually every surface, be sure to wipe everything down regularly, including the steering wheel and door handles. If you have a leather interior, there are auto wipes available for those surfaces. And before you go wipe down any touchscreens, be sure to check your owner’s manual to see if they require any special microfiber cloth.

7. Give your debit cards a wipe.

It’s a good idea to disinfect credit or debit cards that follow you around on shopping excursions. As with all high-touch objects, be sure to wipe them down every day.
