COVID-19 Basics

Symptoms:

  • The most common symptoms are cough and fever. Some patients progress through shortness of breath.
  • Other common symptoms are chills, shivering (shaking), sore throat, muscle pains or body aches, headache and loss of smell or taste.
  • The CDC also includes the following less-common symptoms: runny nose, fatigue (tiredness), nausea, vomiting and diarrhea.
  • Incubation Period: average 5 days (range 2 to 14 days) after coming in contact with the secretions of a person who has COVID-19.
  • No Symptoms but Infected: more than 30% of infected patients have no symptoms.
  • Mild Infections: 80% of those with symptoms have a mild illness, much like normal flu or a bad cold. The symptoms usually last 2 weeks.
  • Severe Infections: 20% of those with symptoms develop trouble breathing from viral pneumonia. Many of these need to be admitted to the hospital. People with complications generally recover in 3 to 6 weeks.
  • Deaths: children generally have a mild illness and recover quickly. Pediatric deaths are very rare. Older adults, especially those with chronic lung disease, heart disease, diabetes or weak immune systems, have the highest death rates. The overall death rate is around 6 per 1,000.
  • Vaccine: there currently is no vaccine to prevent COVID-19. Research is on the fast track in many labs. Safe and effective vaccines may be ready by early 2021. Most vaccines will be 2 doses, given 3-4 weeks apart. Similar to flu shots, they will probably provide protection for 6-9 months. The first widely available vaccines will only be offered to adults. Reason: vaccine safety needed to be proven in adults first and vaccine trials on teens are just starting (November 2020).
  • Treatment: new treatments for severe COVID-19 are becoming available. They are only used on hospitalized patients and are given by IV (in the vein). 

How Is Coronavirus (COVID-19) Spread?

  • COVID-19 is spread from person to person.
  • The virus spreads by respiratory droplets that are produced when a person coughs, sneezes, shouts or sings. The infected droplets can then be inhaled by a nearby person or land on the surface of their face or eyes. 
  • Most infected people also have respiratory secretions on their hands. These secretions get transferred to healthy people on doorknobs, faucet handles, etc. The virus then gets transferred to healthy people when they touch their face or rub their eyes.
  • These methods are how most respiratory viruses spread.

Exposure to COVID-19: Levels of Risk

  • Household Close Contact. Lives with a person who has positive test for COVID-19. This carries the highest risk of spreading the infection.
  • Other Close Contact. The CDC defines 6 feet (2 meters) as how far coughing can spread the virus. How long the close contact lasts can also be important. Prolonged close contact is defined as a total of 15 minutes or more over a 24-hour period (CDC). Close contact includes kissing, hugging or sharing eating and drinking utensils. It also includes close conversations. Direct contact with secretions of a person with COVID-19 is also close contact. Includes being in the same childcare room, classroom or carpool. These exposures are usually lower risk than living with an infected person.
  • In Same Building – Low Risk Exposure. Being in the same school, place of worship, workplace or building carries a small risk for exposure. This risk increases if several people have the infection.
  • In Same City – Low Risk Exposure. Living in or travel from a city or country where there is major community spread of COVID-19, also carries a small risk. The CDC lists these “hot spots.” Outdoor contacts are much safer than indoor contacts.

COVID-19 Testing – Talk with your Doctor:

  • Who can benefit from testing is complicated.
  • The availability of testing and where to get it can be different for every community.
  • Your doctor is the best resource for up-to-date information on testing. Call during office hours.

How to Prevent Getting Coronavirus

There is no vaccine to prevent coronavirus yet. Here are things you can do protect yourself from coronavirus and other viral infections like the flu:

  • Wash your hands often with soap and water (very important). Always do before you eat.
  • Use an alcohol-based hand sanitizer if water is not available. Remember: soap and water work better.
  • Don’t touch your eyes, nose or mouth unless your hands are clean. Germs on the hands can get into your body this way.
  • Don’t share glasses, plates or eating utensils.
  • No longer shake hands. Greet others with a smile and a nod.
  • If you or your child need to be seen for an urgent medical problem, do not hesitate to go in. ERs and urgent care sites are safe places. They are well equipped to protect you against the virus. For non-urgent conditions, talk to your doctor’s office first.

Social Distancing and COVID-19 Prevention

  • Avoid any contact with people known to have COVID-19 infection. Avoid talking to or sitting close to them.
  • Social Distancing: try to stay at least 6 feet (2 meters) away from anyone who is sick, especially if they are coughing. Also called physical distancing. Avoid crowds, because you can’t tell who might be sick.
  • If COVID-19 is widespread in your community, try to stay 6 feet (2 meters) away from everyone outside your family unit.
  • Stay at Home Orders: follow any stay at home (stay in place) orders in your community. Leave your home only for essential needs such as buying food or seeking medical care.
  • After Stay at Home Orders are Lifted: continue social distancing. Also wear a mask when entering any public building or outdoor crowded area. These precautions will be needed for many months. Your state public health department will decide when they are no longer needed.
