Frequently Asked Questions about COVID-19
“Shared expectations lead to predictability.”
11 Q: What is the best way to sanitize money?
A: The consensus is that money is not an important vector of infection for coronavirus-19! Each sub-microscopic virus particle, called a virion, is 1/10,000 of a millimeter wide. This is so small it can only be seen using an electron microscope. If a virion had eyes, which of course it doesn’t, it would find dollar bills quite porous – a honeycomb of spaces between fibers. There is a greatly reduced concentration of virus on the top surfaces for humans to carry to their mouth, nose or eyes. In addition, bills placed in ATM machines, have been counted and sorted by machine, and moved in large stacks, greatly minimizing the surfaces any aerosoled virus would contact.
The NIH has defined the viability of virus on cardboard (and paper) as lasting up to 24 hours, and on hard metallic surfaces for up to 3 days.
For people who want to be extremely over-cautious, use a hand sanitizer before and after placing bills into wallets and purses or simply set them safely aside and leave them there for a few days.
For coins, consider leaving them at the store as change for use by others. If metallic coins are brought home, consider disinfecting them using a bleach solution (1/3 cup of bleach to 1 gallon of water).
Again, it is important to stress the consensus: money is not an important vector of infection for COVID-19.
12 Q: What is the controversy about using an approved drug to treat COVID-19?
A: Hydroxychloroquine is also known by the brand name Plaquenil. It is an established, approved prescription for treatment of malaria and some symptoms of rheumatoid arthritis and autoimmune diseases. Laboratory testing has indicated the possibility of effectiveness against COVID-19. But Deborah Birx, MD of the president’s task force has publicly stated that efficacy in test tubes doesn’t mean it will work in humans.
Small human studies in China and France showed conflicting results. One showed a “good prognosis” and the other showed “no evidence of rapid antiviral clearance or clinical benefit.” Yet, president Trump repeatedly promotes this medication as a “game-changer.” On April 3, 2020, the FDA issued an “emergency use authorization” (EUA) for trial testing of the drug as a last resort treatment of COVID-19 patients.
Cited in this EUA are several contraindications including the presence of vision and heart abnormalities, and abnormal liver or kidney functions.
In spite of additional doses of the drug being manufactured for this testing, there are now shortages available for traditional treatment of rheumatoid arthritis and lupus patients. Test results have yet to be evaluated. Politicians have falsely stated this testing “has given good results,” “and even can be used to prevent the disease in hospital workers.” These are false conclusions because testing is limited to “last resort” use on patients who are near death. Scientists and experts encourage everyone to wait until clinical trials are over and facts are known.
13 Q: For some time now there has been a promise that a vaccine will be available in from 12 to 18 months. When did this period start? When can we expect it to be available?
A The development of a vaccine for COVID-19 must go through three separate phases of clinical development before it can be approved. Each requires a minimum time to be completed. If any negative findings emerge within a step, additional time will be needed to rectify the problems found.
The clock has already started. Many countries are separately at work to identify treatment and vaccination products. Any vaccination safely replicates the disease in an individual leading to their immune system generating specific antigens that would be available if the virus later infects the person.
The first challenge is identifying that the trial vaccine is safe. Can it introduce the disease in a healthy individual without actually infecting them?
The next challenge is to determine if the trial vaccine generates the requisite antigens.
The third phase involves thousands of people given the trial vaccine and evaluating them over months to determine if immunity is actually provided before it is then approved.
Only then will production of the trial vaccine be undertaken over time to produce the hundreds of millions of doses required for the public to receive it.
- Q: It is widely assumed that someone who has recovered from COVID-19 has immunity and could later safely return to work. Is this true?
A: A mid-April finding by the World Health Organization (WHO) puts this assumption in doubt! Dr. Maria Van Kerkhove, who is the WHO’s technical lead on COVID-19, stated that recent findings evaluating immunity suggest different immunity levels exist from previously infected patients. “Right now, we don’t have a full picture of what immunity looks like,” Dr. Van Kerkhove said. “And until we do, we can’t give a complete answer.”
Many of the serology tests being developed are pinprick blood tests that measure raised levels of antibodies used in the body to fight against the virus. It is now reported there is no evidence that this testing can effectively determine levels of immunity in the population. “These tests will be able to measure the level of antibodies, but that does not mean that somebody with antibodies is immune.”
And with the lack of a coordinated federal program for testing, many companies are selling testing kits that are not approved by the FDA! It is suggested that many such kits are giving false negative results – people are identified with antigens that in fact they do not have.
These findings raise questions on developing a safe vaccine that provides immunity. It cautions that groups should not rush to return to normal assuming those with antibodies can safely return to work. To do so before science verifies the level of immunity may place these people at risk of suffering a second attack of COVID-19.
Scientists are working now to study this issue of immunity before any vaccine reaches that third phase of testing.
15 Q: I saw something on the Internet that said hair dryers could be used to destroy live virus on objects and surfaces. Is this true?
- There is a lot of misinformation on the Internet and social media. Hair dryers and several herbs to destroy the virus or reduce the chance of infection are among these. There are also many scams trying to feed on people’s fears to make money. Private sale of face masks guaranteed to filter COVID-19 and specific foods and “medicines” guaranteed to prevent symptoms all can be bought with “free delivery” offered as an incentive
Some sites are even falsely using the CDC emblem or logo to mislead the unwary. Double check any information before you decide to either make purchases, give credit card information, or practice the recommended activities. For example, one can Google “What is the CDC guideline for using hair dryers?” After looking at several sites that don’t identify such a guideline, you will actually find one that states this rumor comes from as an unauthorized video and suggests this advice should not be followed!
