Face masks help limit the spread of COVID-19 by catching respiratory droplets that are released when people sneeze, cough, or talk. According to Dr. Steve Pergam, MPH, medical director of infection prevention at Seattle Cancer Care Alliance, this is how the virus spreads person to person through these droplets.
When a person nearby inhales the droplets or the droplets land inside their mouth or nose, they could contract an infection with the virus. They could also likely contract the virus by touching a contaminated mask then touches their mouth or nose.
Cleaning and sanitizing your mask is essential to limit the possibility of contracting the virus from contaminated surfaces, including face masks.
This article will show how to safely disinfect common types of masks for reuse and handle medical-grade masks that cannot be easily cleaned outside of a medical setting.
Cloth Face Coverings
Debra Goff, PharmD, FIDSA, FCCP, an infectious diseases specialist and pharmacy professor at The Ohio State University Wexner Medical Center, states that bandanas, cloth masks, neck gaiters, and scarves are masks that can be cleaned and reused.
If you plan to machine-wash your mask, first, wash your hands. Then remove the mask and do not touch your eyes, nose, or mouth, Goff advises.
Place the mask directly into the washing machine then wash your hands immediately.
Goff recommends using your regular laundry detergent in addition to bleach and the warmest water recommended for that fabric type. Once the mask is washed, dry on high heat until it’s completely dry.
For hand-washing your mask, she suggests following the same method washing your hands before removing your face mask.
To disinfect your mask properly, soak it in a bleach solution containing four teaspoons of household bleach per each quart of water for 5 minutes.
Then soak the mask, and rinse thoroughly with water, and let the mask air-dry.
Goff states it’s best to clean cloth face masks after each use.
Kaiming Ye, Ph.D., professor and department chair of biomedical engineering and director of the Center of Biomanufacturing for Regenerative Medicine at Binghamton University, State University of New York, states that some masks, like N95 and surgical masks, are intended for single-use only.
This means the masks should be thrown away in the trash after wearing them for the average person.
Ye says these masks can be reused in professional settings, however, if properly sanitized. He says N95 masks can be disinfected by UVC germicidal irradiation or vapor phase hydrogen peroxide.
However, there have been no tests performed on surgical mask disinfection or reuse as the demand is low, Ye notes. Goff suggests inspecting the mask when you take it off when you can’t replace your mask between each use.
If the face mask is dirty, torn, or saturated with moisture, she says you should discard it. Suppose it appears to be clean and intact. In that case, she recommends storing it in a clean paper bag or another breathable container between uses.
Ideally, however, they shouldn’t be reused.
Since face shields open on the side, they don’t protect you from sneezes or coughs behind you. Face shields, however, protect your eyes.
Goff says face shields are often worn with a face mask for added protection. When it comes to cleaning face shields, first wipe down the inside using a clean cloth saturated with a neutral detergent solution or cleaner wipe.
Then wipe down the outside using a disinfectant wipe or clean cloth saturated with a disinfectant solution. Followed by wiping the outside of the face shield with clean water or alcohol to remove the residue.
Allow the face shield to air-dry, and finally, wash your hands when you’re done. Face masks are an essential way to prevent and limit the spread of COVID-19.
Make sure your face masks are cleaned or discarded after use by following these guidelines on how to keep every type of face mask sanitized. Keep in mind that medical masks are not designed for reuse. Face shields may be used in addition to a face mask for more protection, and should also be cleaned between uses.
Getting Back Into Shape During Covid
The motivation to stay active during quarantine can be quite difficult, especially with many opting to use garages or bedrooms as a personal gym without any equipment or legroom available. Even as gyms reopen, understanding what your body needs to become stronger, leaner, & fitter can be a difficult challenge to tackle.
Keep in mind that your level of progression is widely based on your total time off, and your level of fitness before it. If you start by placing a high demand on your body, you risk the possibility of injury and a quick regression backward. Being extremely sore the next day does not indicate a quality workout. Here is an outline to guide and help you ease back into your workout without losing motivation or risking injury.

1. Start with Flexibility Workouts
Your first progressive step should be to incorporate a couple of days of flexibility workouts to increase blood flow and circulation while supporting range of motion and joint mobility. Developing flexibility is one of the most overlooked protocols of fitness routines, and building these protocols early on will allow your body to properly readjust to the new demands that will be placed on it. Signing up or participating in a beginner yoga class or videos you can do at home to increase flexibility and build strength. Choose 10 to 15 stretches, performing each flexibility movement for up to one minute.
2. Add Easy Cardio
The next step is integrating light cardiorespiratory workouts after a couple of stretching or yoga sessions. An excellent way to start is a brisk 20-minute outdoor walk that will revitalize your mind and get your body moving again. Other options you can include in your workout, such as low impact HIIT workout (high-intensity interval training) for beginners. Machines you can use at your gyms include treadmills, ellipticals, and stationary bikes are great indoor options. If you had a well-established fitness base before a month-long break, your first week might consist of light jogging instead of walking.
3. Start Strength Training
After your first week of flexibility and light cardio, start to incorporate strength workouts into your routine by trying gentle strength training workout for getting back into the gym. The time apart from the gym most likely involved a fair amount of sitting that causes weakness in your posterior chain, which refers to all the muscles on the backside of the body from your head down to your heels. These particular muscles are essential for basic everyday movement and keep your spine upright when at the desk. That is why incorporating exercises that improve your posture, develop core strength, and activate muscles throughout your glutes and hamstrings are essential.
Exercises like squats, lunges, bridges, TRX hamstring curls, stability ball mobility, and core work will help activate these muscles. Bodyweight workouts are ideal for working these muscles and establish a safe transition back into your fitness regimen, and you can work within your fitness level.
4. Begin your workout with a proper warm-up and end with a good cool-down
It is important to begin your workout with a proper warm-up that prepares your body for the increase in activity, and a cool-down helps your heart rate return to normal resting rate. Don’t jump into any physical activity without easing into it. Muscles that have not been accustomed to strenuous activity for a while, and will experience some form of DOMS (delayed onset muscle soreness), which means you will be tight and achy for 24-72 hours after your workout. You may also experience this when you work out regularly but up to your intensity. With a proper cool-down session, you can help some of the soreness you could experience the day following your workout.
5. And spend a few minutes stretching.
Stretching is an important dynamic when getting back into your fitness routine to help loosen those tight muscles before starting your workouts. After your workout, its good to release that muscle tension.
6. Focus on your form
When you’re getting back into your regular routine, quality will always trump quantity. Maintaining proper form will help target and work your muscles without straining or overexerting yourself. Take your time to focus on your form, breathing, and control. This is extremely important because proper technique and form are crucial to help prevent injury.
7. Don’t skip rest days!
Don’t jump into working out a six-days-a-week workout routine too soon. Recovery is a big part of being active. When you don’t take a day off, your body doesn’t get to take the necessary time to replenish your muscles. Rest days are vital to long-term wellness, and the lifestyle you are recreating for yourself now should consist of frequency. Promoting recovery is a good way to build habits of your workouts without leading to a sprain or strain delaying your workout and fitness routines.
8. Listen to your body
Your body will let you know when it is working hard, but learning the difference between hurts-so-good and hurts-not-so-good will save you a trip to the doctor’s office. If something feels uncomfortable or causes you pain, stop doing whatever is causing your body to feel that way. There is a not-so-fine line between muscle discomfort from a good workout, and pain lets you know something’s not right. Be attentive to your body to help you progress through your workouts safely.
Slowly easing your way to recreating your fitness regimen will help you stay consistent and achieve your fitness goals. It’s important to remember we are all on our fitness journey, so take your time and stay motivated!
New Promising COVID-19 Vaccine Selects Hoag Hospital for Trial
UCI graduate Chen Cao became the first of 35 individuals to be vaccinated in NantKwest Inc. and ImmunityBio’s phase 1 clinical trial for COVID-19. This trial is only happening at Hoag Memorial Hospital Presbyterian in Newport Beach, CA.
According to the WHO, there are 44 vaccine candidates in clinical evaluation worldwide and another 154 in preclinical evaluation. Most are targetting the coronavirus’ signature spike protein, which leads to its name “corona,” meaning “crown” in Latin.
Philip Robinson, Hoag’s medical director of infection prevention and principal investigator for the vaccine trial, states, “This vaccine is novel because it stimulates the second arm of the immune system, the cell-mediated immunity, the T-cell response.”
Based on SARS-CoV 1, he added that patients who developed that T-cell and cellular immune response have long-lasting immunity that can be measured 17 years after they got infected. T-cell responses are more durable than antibody responses activated by the spike protein alone and develop a much longer-term immunity, the company states.
This vaccine’s dual-edged approach is a “key advantage” that could also prevail in mutations in the spike proteins, which might reduce the efficacy of “S-only” vaccines moving forward. There are several other features that the NantKwest/ImmunityBio vaccine has that is generating enthusiasm.
While several vaccine candidates are using adenoviruses — which cause the common cold — to transfer the coronavirus’ genetic material into the human body to hopefully induce an immune response, however, there’s a potential risk that the body’s immune systems could recognize the cold virus and attack before it can complete its task. This vaccine overcomes this challenge by making deletions to the adenovirus that render it invisible, Robinson said.
Similar to other vaccine candidates, this one will consist of two shots, three weeks apart. But apart from many others, it won’t need to be stored in frigid temperatures, which can pose significant logistical challenges.
Instead, it just requires standard refrigeration and can remain viable at room temperature “for quite a long time,” Robinson said. Down the line might also be delivered by mouth or by nasal spray, rather than just by injection, making administration even easier.
Last Wednesday, five volunteers received their first injections at Hoag, and five more will get their first injections this week, according to Deborah Fridman, Hoag’s director of clinical research. There will be a pause after each set of 10 to review the safety, side effects, and immune system reactions.
This phase 1 trial’s primary goal is to confirm the vaccine’s safety and induces immunity, Fridman said. If proven successful, it will expand into phases 2 and 3 next year, recruiting hundreds, and then thousands, of participants.
Hoag Hospital has participated in more than 20 COVID-19 clinical trials since caring for the state’s first known COVID-19 patient in January. Hoag has given patients access to advanced therapies and innovative treatments, officials said. Though, this vaccine is its first COVID-related vaccine trial.
The hospital has expanded its research department in recent years. Hoag has a relationship with Los Angeles County-based NantKwest, Inc., and ImmunityBio is the only Orange County hospital. It is the only nonacademic institution to offer the companies’ phase 2 immunotherapy clinical trial for solid tumors.
Patient No. 1 Chen Cao must report any side effects to Hoag immediately. She has a diary to record how she’s feeling and will return regularly for evaluation and blood draws.

Health Officials in Orange County Warn Residents of Flu and Coronavirus ‘twindemic’
Fall has officially begun with another flu season in store, but this year, public health officials and politicians are warning the flu could increase the demand on Orange County’s health care grid, which has been stressed due to the coronavirus pandemic.
A second outbreak is a primary concern with cooling temperatures approaching, and relaxing pandemic rules could lead to more people gathering in tighter quarters.
County leaders are urging residents to maintain their pandemic habits, to help prevent a so-called “twindemic” of influenza and the coronavirus, and advise residents to get a flu shot.
Andrew Noymer, an epidemiologist and professor of public health at UCI, states that the driving factor is COVID, a new virus, and the flu shot is not.
Both are respiratory diseases with similar transmission modes such as coughs and sneezes spouting infectious droplets around – the flu has been around for centuries, and health systems know how to manage it, Noymer stated.
The COVID-19 countermeasures like wearing face masks, social distancing, and frequent hand washing will also work against the flu.
One concern is that both diseases share symptoms that could cause the lesser-studied COVID-19 to spread undetected if a sick person believes they have the flu, Noymer said. That will be a challenge for an already stressed healthcare system, he said.
Annual flu hospitalizations could cause hospitals to maintain pandemic surge plans that added beds and staff. Healthcare providers are spreading the message to their patients ahead of the expected strain.
This week, Kaiser Permanente emailed Orange County members with a video explaining the differences between a seasonal cold, the flu, and COVID-19.
The differences between all three can be hard to distinguish, which is why mild coronavirus cases might go undetected, the video explains. The main symptoms of COVID-19 include fever, cough, shortness of breath, with onset up to two weeks after exposure. As with influenza or the flu, it starts suddenly with fever, cough, sore throat, nasal congestion, and body aches.
Meanwhile, common colds slowly take hold with symptoms, including a runny nose, sore throat, sneezing, headaches, and high fevers are rare.
The flu kills 60,000 people per year nationwide, Noymer said, but “COVID-19 has killed 200,000, and the year is not even over yet,”
According to public health data, since 2017, influenza and pneumonia have killed an average of 576 people per year in Orange County. Since March, the COVID-19 death toll among residents has climbed to more than 1,100 people.
For health experts, the coronavirus still is the wildcard as winter approaches. Noymer further added that the county’s population is more susceptible to COVID than the flu because they have flu shots and currently don’t have a COVID shot.
Recently, Dr. Robert Redfield, the director of the US Centers for Disease Control and Prevention, told a Senate subcommittee he suspects a COVID-19 vaccine will be available in the U.S. by December in limited supply.
