We all know her best as Mary Ann Summers, stranded on Gilligan’s Island from September 26, 1964, to April 17, 1967. She was born in Reno, Nevada October 18, 1938 and in 1959 would be crowned Miss Nevada and compete for Miss America 1960. She made her acting debut on ABC’s The Roaring 20’s and the movie The New Interns.
I work at Stacy’s Compounding Pharmacy, in Atlanta, and since the pandemic struck we get customers occasionally coming in telling us that the CDC has said that masks do no good for stopping Covid-19.
I decided to do a little research and find out for myself. The first thing I did was ask our pharmacist, Kelly Howard. She has a friend working with Covid at the CDC and she says that masks were highly recommended.
Their website wants people to wear masks in public settings, around people not in your own household, especially when social distancing is not possible. The CDC goes on the say that they should not be worn by children under two years old,
people that may have trouble breathing, unconscious, incapacitated or unable to remove their own mask. They also agree with common sense saying that your mask acts as a barrier to prevent your respiratory droplets, which carry the virus, from traveling through the air and onto other people or surfaces. Wearing a mask with an exhalation valve or vent defeats the purpose, allowing droplets to escape into the air.
Kelly’s Mother-in-law was diagnosed with possible Corona Toe? She complained of sore, discolored toes and the dermatologist diagnosed it as such. She is being tested to see if she has had the virus. Results to come. Update: She did not have the virus although they did not do the antibody tests so she could have had it previously.
[From thejakartapost.com] Since the outbreak of COVID-19, sales of hand sanitizers have soared. It’s become such a sought-after product that pharmacies and supermarkets have started limiting the number that people can buy at one time. New York state has even announced it will start producing its own hand sanitizer to meet demand. Though hand sanitizers can help reduce our risk of catching certain infections, not all hand sanitizers are equally effective against coronavirus.
Aside from inhaling droplets, you can also get respiratory viruses including SARS-CoV-2 by touching anything contaminated with the virus and then touching your face, in particular your mouth or nose. We touch our faces a lot without even realising it. A study from New South Wales found that people touch their faces about 23 times an hour
Washing with warm water and soap remains the gold standard for hand hygiene and preventing the spread of infectious diseases. Washing with warm water (not cold water) and soap removes oils from our hands that can harbour microbes.
But hand sanitizers can also protect against disease-causing microbes, especially in situations when soap and water aren’t available. They’re also proven to be effective in reducing the number and type of microbes.
There are two main types of hand sanitizers: alcohol-based and alcohol-free. Alcohol-based hand sanitizers contain varying amounts and types of alcohol, often between 60 percent and 95 percent and usually isopropyl alcohol, ethanol (ethyl alcohol) or n-propanol. Alcohol is known to be able to kill most germs.
Alcohol-free hand sanitizers contain something called quarternary ammonium compounds (usually benzalkonium chloride) instead of alcohol. These can reduce microbes but are less effective than alcohol.
Not only are alcohol-based hand sanitizers found to be effective at killing many types of bacteria, including MRSA and E coli, they’re also effective against many viruses, including the influenza A virus, rhinovirus, hepatitis A virus, HIV, and Middle East respiratory syndrome coronavirus (MERS-CoV).
Alcohol attacks and destroys the envelope protein that surrounds some viruses, including coronaviruses. This protein is vital for a virus’s survival and multiplication. But a hand sanitizer needs to be at least 60% alcohol in order to kill most viruses.
Hand sanitizers with less than 60 percent alcohol were also found to be less effective at killing bacteria and fungi and may only reduce the growth of germs rather than killing them outright.
And even hand sanitizers containing 60 percent alcohol can’t remove all types of germs. Studies have found that hand washing is more effective than hand sanitisers at removing norovirus, Cryptosporidium (a parasite that can cause diarrhea), and Clostridium difficile (bacteria which cause bowel problems and diarrhea).
With shortages leading some people to try and make their own hand sanitizers, it’s also important to know these might not be as effective as commercially available products.
If hands are visibly dirty, hand washing with soap and water is more effective than using alcohol-based hand sanitizers. Research has found that the detergent effect of soap and the friction of washing work together to reduce the number of microbes on our hands, as well as the dirt and organic materials.
Sneezing or coughing into your hands also requires more than just a pump of hand sanitizer to disinfect them. This is because if your hands are contaminated with mucous, the hand sanitizer might not work as well because mucous acts to protect microbes.
As a result, the best and most consistent way of preventing the spread of the coronavirus – and reducing your risk of contracting it – remains washing your hands with soap and water as a first choice, and avoiding touching your face as much as possible.
But alcohol-based hand sanitizers (with at least 60 percent alcohol) are a practical alternative when soap and water aren’t available. If you are using hand sanitizer then, just like when washing with soap and water, you need to make sure you cover your hands (including between your knuckles, wrists, palms, back of your hand and your fingernails) fully, rubbing it in for at least 20 seconds so it’s truly effective.
