Can I use a mask microwave? Is it safe to swim?



The surge in COVID-19 cases in California has renewed concerns about disinfection and virus transmission. This week, a new survey by the US Centers for Disease Control and Prevention revealed that 54% of patients do not know how they get sick.

To answer your question, we have studied the answers of the experts, and as the pandemic continues, their knowledge is increasing. Their answers and information collected from other sources are summarized here.

ask: Can microwave kill the virus on my mask? What is the best cleaning method?

A: Fire safety officials warn against using microwave ovens to disinfect masks. Gas masks may melt, burn, or catch fire. The metal nose wire of disposable masks can cause sparks and damage the microwave oven.

Instead, CDC recommends the use of washing machines. You can include masks in your clothing. Use regular washing powder and the warmest appropriate water level. If you wash by hand, you should prepare a bleach solution by mixing one-third cup of household bleach per gallon of warm water

After cleaning, make sure to completely dry the cloth mask. In the dryer, use the highest heat setting. If the air is dry, lay it flat. If possible, place the cloth mask in direct sunlight.

ask: Is it safe to swim or sail?

A: When swimming in a swimming pool, the risk of infection with COVID-19 is small because the disinfectants (including chlorine and bromine) used to clean the water can kill the virus. Water in lakes and oceans should also be safe, because viruses will be diluted by large amounts of water. Unlike bacteria, respiratory viruses cannot survive on their own in water.

The biggest risk is not swimming, but the time spent around the pool, especially in large groups. Therefore, gathering at a crowded beach is a bad idea. Take precautions and keep a distance physically. Of course, if you feel unwell, please stay at home.

If renting a paddle board or sailboat, keep a distance from the workers, wear a mask, and ensure that any shared equipment (such as paddles, paddles, or boats) that the opponent and hands touch are disinfected.

ask: Is hand sanitizer better than soap? Can I use salt water?

A: Soap and water are the best choices for hand washing. Both liquid soap and bar soap contain the same elements: fat or oil, water and alkali (commonly called lye). This combination can wash away dirt, grease and bacteria that stick to it.

If you do not have access to soap and water, the Centers for Disease Control and Prevention recommends using a hand sanitizer made of at least 60% alcohol. It is not recommended to use saline or saline to disinfect your hands.

ask: What precautions should pregnant women take during this coronavirus period? If the pregnant woman is infected, is it harmful to the baby?

A: According to the Centers for Disease Control and Prevention (CDC), pregnant women seem to have the same chance of being infected as other people of the same age. The advice for pregnant women is the same as for everyone else: wash your hands often with soap and water, disinfect surfaces that you frequently touch, and socialize. Newborns are rarely infected with this virus, but it is possible.

Based on our current understanding, pregnant women may have a higher risk of serious illness from COVID-19 than women who are not pregnant. In addition, COVID-19 pregnant women may be at increased risk of adverse pregnancy outcomes (such as preterm birth).

The American Academy of Pediatrics recommends that mothers suspected of having COVID-19 infection wear masks and take strict hygiene precautions when breastfeeding. No COVID-19 virus was found in breast milk.

ask: Is the CPAP machine used by sleep apnea patients effective for patients who are only slightly tortured by COVID-19?

A: The American Society of Anesthesiologists and other medical experts warn that using CPAP machines may increase the risk of spreading the virus. Both ventilator and CPAP machines can help people breathe, while ventilator is a closed system. They use breathing tubes and filter the exhaled air. On the other hand, CPAP machines use masks to allow unfiltered air to escape.

ask: Does Advil make COVID-19 worse? Is Tylenol (acetaminophen) OK?

A: Although the World Health Organization previously recommended the use of acetaminophen instead of ibuprofen, the recommendation was later withdrawn. According to the FDA, neither drug has been shown to aggravate coronavirus-related symptoms.

ask: When you are infected with the virus, can over-the-counter MUCINEX (guaifenesin) or Robitussin (dextromethorphan) effectively relieve lung congestion?

A: If you have symptoms of COVID-19, please call your doctor to determine the best treatment plan. In mild cases, guaifenesin or other expectorants can help thin the chest and throat. Although this can make the patient feel better, it will not kill the virus.

According to the American Association of Hospital Pharmacists, the Infectious Disease Research Group also recommends the use of throat lozenges and fever inhibitors, such as acetaminophen or ibuprofen, to relieve symptoms. (But similar to expectorants, these drugs do not address the root cause of the new coronavirus.)

ask: I have a full spectrum of light-will it kill the virus if used?

A: Sunlight contains three types of radiation: UVA, UVB and UVC. All three can damage the skin and eyes.

Studies have shown that ultraviolet light can kill airborne viruses, so it can be disinfected when there are no people in hospitals, subways, and other public places. However, it has not been shown that ultraviolet light can prevent human infection of COVID-19 or kill the virus of infected patients-ultraviolet light is the most dangerous of these three types of radiation. It is forbidden to use ultraviolet light to disinfect the body. At present, there is little research on whether ultraviolet rays can provide an effective method of disinfecting personal protective equipment.
