Coronavirus: What you need to know and how to reduce the risk of infection

The temporarily named 2019-nCoV is a coronavirus spread by respiratory droplets expelled (about 3 to 6 feet) through coughing and sneezing. Symptoms may not appear right away.

As tension mounts over the outbreak of 2019-nCoV, a previously unknown coronavirus, patients in North Texas should know the facts about the disease – and basic tips to prevent its spread.

The virus is suspected to have originated in a seafood market in Wuhan, China, and has spread to multiple countries, including the U.S. It causes symptoms similar to pneumonia:

  • Chest congestion and discomfort
  • Cough
  • Difficulty breathing
  • Fever, though it might not be a symptom for infants, the elderly, or those with suppressed immune systems
  • Sore throat
  • Malaise, or a general unwell feeling
  • In the most severe cases, organ failure

Coronaviruses are a family of respiratory viruses that spread quickly. The novel coronavirus 2019-nCoV is believed to be spread by respiratory droplets expelled (about 3 to 6 feet) through coughing and sneezing. Symptoms may not appear right away.

UT Southwestern’s infectious diseases and infection prevention teams have created a patient screening procedure to be used at clinic and hospital check-ins. It can provide swift, appropriate care and reduce the risk of exposure to others.

While hospital and airport screening protocols can help contain the disease, individuals can reduce risk through the basics of viral disease prevention. (See tips below.)

What we know about 2019-nCoV


Risk factors

Those at risk include any of these within 14 days prior to symptom onset:

  • Travel to Wuhan City and China
  • Having direct contact or being within six feet of a patient diagnosed with 2019-nCoV viral infection without personal protection such as gloves or goggles 


Patients can be diagnosed from samples from the nares/throat, or sputum, or samples from bronchial fluid. Blood and stool samples also may be requested. Samples are sent to the CDC for testing.

There is currently no vaccine or specific antiviral treatment for 2019-nCoV. The CDC recommends resting at home and drinking plenty of fluids. Some patients may benefit from pain and fever relievers. Using a humidifier or taking a hot shower can ease chest discomfort and aid breathing.

If you are infected, your doctor will work with you to control symptoms and reduce the risk of spreading the virus to others.

Prevention tips: Back to the basics

Proper handwashing is the No. 1 recommendation from the CDC. Whether you use soap and water or an alcohol-based sanitizer, proper hand hygiene gives you more control over your health – and it can reduce the risk of respiratory virus transmission by 21%.

WHO and the CDC also recommend these guidelines to protect yourself: 

  • Avoid touching your eyes, nose, and mouth, especially in public
  • Avoid close contact with people who are sick
  • Cover your mouth with your arm/elbow when you cough or sneeze
  • Stay home if you are sick
  • Get your flu shot 

That last one gives people pause – 2019-nCoV is not the same as the flu, so how can it help?

Getting vaccinated against the flu helps in several ways. First, the flu is circulating at the same time as 2019-nCoV is rising, and the symptoms are similar. So, knowing whether you've been vaccinated against the flu helps us sort out the conditions for which it makes sense to test.

Second, the flu is deadly every year. WHO estimates that more than 290,000 to 650,000 people will die of the flu in 2020. So far in the U.S., 8,000 people have died from influenza. The death toll for the current outbreak of 2019-nCoV has not approached those levels.

But the 2019-nCoV coronavirus is dynamic, with new information released every few hours. Find the latest updates and recommendations on the websites for WHO and CDC.

If you are concerned you've been exposed, call 214-645-2800 or request an appointment online to visit with an infectious disease specialist.
