Coronavirus Precautions You Must Take

A virologist’s prep plan went “viral” online—here’s what he recommended.

Dr. James Robb, MD, FCAP, circulated an email that we think is the soundest advice yet on what you can do to prevent the spread of the coronavirus. Eat This, Not That! Health shares it with you here; please share with everyone you know:

When I was a professor of pathology at the University of California San Diego, I was one of the first molecular virologists in the world to work on coronaviruses (the 1970s). I was the first to demonstrate the number of genes the virus contained. Since then, I have kept up with the coronavirus field and its multiple clinical transfers into the human population (e.g., SARS, MERS), from different animal sources.

The current projections for its expansion in the US are only probable, due to continued insufficient worldwide data, but it is most likely to be widespread in the US by mid to late March and April. Here is what I have done and the precautions that I take and will take. These are the same precautions I currently use during our influenza seasons, except for the mask and gloves.

1

No Handshaking

Use a fist bump, slight bow, elbow bump, etc.

2

Use Only Your Knuckle

…to touch light switches. elevator buttons, etc.. Lift the gasoline dispenser with a paper towel or use a disposable glove.

3

Open Doors With Your Closed Fist or Hip

Do not grasp the handle with your hand, unless there is no other way to open the door. Especially important on bathroom and post office/commercial doors.

4

Use Disinfectant Wipes

…at the stores when they are available, including wiping the handle and child seat in grocery carts.

5

Wash Your Hands With Soap

…for 10-20 seconds and/or use a greater than 60% alcohol-based hand sanitizer whenever you return home from any activity that involves locations where other people have been.

6

Keep a Bottle of Sanitizer

…available at each of your home's entrances. And in your car for use after getting gas or touching other contaminated objects when you can't immediately wash your hands.

7

Cough or Sneeze into a Disposable Tissue

…and discard. Use your elbow only if you have to. The clothing on your elbow will contain an infectious virus that can be passed on for up to a week or more!

8

Use Latex or Nitrile Latex Disposable Gloves

…for use when going shopping, using the gasoline pump, and all other outside activity when you come in contact with contaminated areas. Note: This virus is spread in large droplets by coughing and sneezing. This means that the air will not infect you! But all the surfaces where these droplets land on are infectious for about a week on average—everything that is associated with infected people will be contaminated and potentially infectious. The virus is on surfaces and you will not be infected unless your unprotected face is directly coughed or sneezed upon. This virus only has cell receptors for lung cells (it only infects your lungs). The only way for the virus to infect you is through your nose or mouth via your hands or an infected cough or sneeze onto or into your nose or mouth.

Stock Up Now on Disposable Surgical Masks

…and use them to prevent you from touching your nose and/or mouth. (We touch our nose/mouth 90 times a day without knowing it!) This is the only way this virus can infect you—it is lung-specific. The mask will not prevent the virus in a direct sneeze from getting into your nose or mouth—it is only to keep you from touching your nose or mouth.

Stock Up Now on Hand Sanitizers

…and latex/nitrile gloves (get the appropriate sizes for your family). The hand sanitizers must be alcohol-based and greater than 60% alcohol to be effective.

11

Stock Up Now with Zinc Lozenges

These lozenges have been proven to be effective in blocking coronavirus (and most other viruses) from multiplying in your throat and nasopharynx. Use as directed several times each day when you begin to feel any "cold-like" symptoms beginning. It is best to lie down and let the lozenge dissolve in the back of your throat and nasopharynx. Cold-Eeze lozenges is one brand available, but there are other brands available.

A Final Word

I, as many others do, hope that this pandemic will be reasonably contained, but I personally do not think it will be. Humans have never seen this snake-associated virus before and have no internal defense against it. Tremendous worldwide efforts are being made to understand the molecular and clinical virology of this virus. Unbelievable molecular knowledge about the genomics, structure, and virulence of this virus has already been achieved. But there will be no drugs or vaccines available this year to protect us or limit the infection within us. Only symptomatic support is available.

I hope these personal thoughts will be helpful during this potentially catastrophic pandemic. Good luck to all of us!
