All You Need To Know About The Coronavirus!

Symptoms and Diagnosis

Symptoms

Common human coronaviruses

Common human coronaviruses, including types 229E, NL63, OC43, and HKU1, usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. Most people get infected with these viruses at some point in their lives. These illnesses usually only last for a short amount of time. Symptoms may include

  • runny nose
  • headache
  • cough
  • sore throat
  • fever
  • a general feeling of being unwell

Human coronaviruses can sometimes cause lower-respiratory tract illnesses, such as pneumonia or bronchitis. This is more common in people with cardiopulmonary disease, people with weakened immune systems, infants, and older adults.

Other human coronaviruses

Two other human coronaviruses, MERS-CoV and SARS-CoV have been known to frequently cause severe symptoms. MERS symptoms usually include fever, cough, and shortness of breath which often progress to pneumonia. About 3 or 4 out of every 10 patients reported with MERS have died. MERS cases continue to occur, primarily in the Arabian Peninsula. SARS symptoms often included fever, chills, and body aches which usually progressed to pneumonia. No human cases of SARS have been reported anywhere in the world since 2004.

Diagnosis

Your healthcare provider may order laboratory tests on respiratory specimens and serum (part of your blood) to detect human coronaviruses. Laboratory testing is more likely to be used if you have severe disease or are suspected of having MERS.

If you are experiencing symptoms, you should tell your healthcare provider about any recent travel or contact with animals. Most MERS-CoV infections have been reported from countries in the Arabian Peninsula. Therefore reporting a travel history or contact with camels or camel products is very important when trying to diagnose MERS.

Transmission

Human coronaviruses most commonly spread from an infected person to others through

  • the air by coughing and sneezing
  • close personal contact, such as touching or shaking hands
  • touching an object or surface with the virus on it, then touching your mouth, nose, or eyes before washing your hands
  • rarely, fecal contamination

In the United States, people usually get infected with common human coronaviruses in the fall and winter. However, you can get infected at any time of the year. Most people will get infected with one or more of the common human coronaviruses in their lifetime. Young children are most likely to get infected. However, people can have multiple infections in their lifetime.

Prevention and Treatment

Prevention

How to protect yourself

There are currently no vaccines available to protect you against human coronavirus infection. You may be able to reduce your risk of infection by doing the following

  • wash your hands often with soap and water for at least 20 seconds
  • avoid touching your eyes, nose, or mouth with unwashed hands
  • avoid close contact with people who are sick

For information about hand washing, see CDC’s Clean Hands Save Lives!

How to protect others

If you have cold-like symptoms, you can help protect others by doing the following

  • stay home while you are sick
  • avoid close contact with others
  • cover your mouth and nose with a tissue when you cough or sneeze, then throw the tissue in the trash and wash your hands
  • clean and disinfect objects and surfaces

Treatment

There are no specific treatments for illnesses caused by human coronaviruses. Most people with common human coronavirus illness will recover on their own. However, you can do some things to relieve your symptoms

  • take pain and fever medications (Caution: do not give Aspirin to children)
  • use a room humidifier or take a hot shower to help ease a sore throat and cough

If you are mildly sick, you should

  • drink plenty of liquids
  • stay home and rest

If you are concerned about your symptoms, you should see your healthcare provider.
