SAN FRANCISCO (CBS SF) — Here’s a rundown on what you need to know about the coronavirus outbreak from the Centers for Disease Control and Prevention.

Symptoms

For confirmed coronavirus infections, reported illnesses have ranged from people with little to no symptoms to people being severely ill and dying. Symptoms can include:

  • Fever
  • Cough
  • Shortness of breath

CDC believes at this time that symptoms of 2019-nCoV may appear in as few as 2 days or as long as 14 after exposure. This is based on what has been seen previously as the incubation period of MERS viruses.

Prevention
There is currently no vaccine to prevent coronavirus infection. The best way to prevent infection is to avoid being exposed to this virus. However, as a reminder, CDC always recommends everyday preventive actions to help prevent the spread of respiratory viruses, including:

  • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
  • If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
  • Avoid close contact with people who are sick.
  • Stay home when you are sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.

Recently Returned Travelers from China
If you were in China in the last 14 days and feel sick with fever, cough, or difficulty breathing, you should:

  • Seek medical advice – Call ahead before you go to a doctor’s office or emergency room. Tell them about your recent travel and your symptoms.
  • Avoid contact with others.
  • Do not travel while sick.

  • Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing.
  • Wash your hands with soap and water immediately after coughing, sneezing or blowing your nose. If soap and water are not readily available, you can use an alcohol-based hand sanitizer that contains at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
  • Take your temperature with a thermometer 2 times a day and watch your health
  • If you develop a fever (100.4 degrees F or higher), cough or have difficulty breathing call your doctor immediately
  • Here’s What Not To Do During The Current Coronavirus Outbreak

    • Do not travel to China
    • Do not use facemasks. CDC does not recommend the use of facemasks for the general public to prevent the spread of coronavirus.
    • Do not show prejudice to people of Asian descent, because of fear of this new virus. Do not assume that someone of Asian descent is more likely to have coronavirus. All persons in the U.S.—including those of Asian descent—who have not traveled to China or been in contact with someone with a confirmed or coronacvirus case in the last 14 days are at low risk of becoming sick.

    How It Spreads

    Much is unknown about how the coronavirus spreads. Current knowledge is largely based on what is known about similar coronaviruses. Coronaviruses are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as with MERS, SARS, and now with the coronavirus 2019-nCoV.

    Most often, spread from person-to-person happens among close contacts (about 6 feet). Person-to-person spread is thought to occur mainly via respiratory droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory pathogens spread. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. It’s currently unclear if a person can get 2019-nCoV by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes.

    Typically, with most respiratory viruses, people are thought to be most contagious when they are most symptomatic (the sickest).

    It’s important to note that how easily a virus spreads person-to-person can vary. Some viruses are highly contagious (like measles), while other viruses are less so. There is much more to learn about the transmissibility, severity, and other features associated with 2019-nCoV and investigations are ongoing.
