COVID 19 Coronavirus Outbreak

Article No. 38
25/January/2020

Coronavirus disease 2019 (COVID-19), also known as 2019-nCoV acute respiratory disease, is an infectious disease caused by SARS-CoV-2 (2019 novel coronavirus), a virus closely related to the SARS virus. It is thought to primarily spread between people via respiratory droplets from infected individuals as they cough or sneeze. Time from exposure to onset of symptoms is generally between 2 to 14 days. Transmission may be limited by handwashing. It often presents with fever, coughing, shortness of breath, pain in the muscles and tiredness, although some may have few or no symptoms. Complications may include pneumonia and acute respiratory distress syndrome. Currently, there are no vaccines or specific antiviral treatments, with therapy being symptomatic, supportive, and experimental.

Cases were initially identified in Wuhan, capital of Hubei province in China in December 2019. Subsequently, infections have been reported around the world. Cases reported outside China have predominantly been in people who have recently travelled to Mainland China.

The World Health Organization (WHO) and U.S. Centers for Disease Control (CDC) recommend that persons who suspect that they are carrying the virus wear a surgical face mask and seek medical advice by calling a doctor rather than directly visiting a clinic in person. The WHO has declared the 2019–20 coronavirus outbreak to be a Public Health Emergency of International Concern (PHEIC). As of 11 February 2020, only Mainland China is listed as an area with known ongoing community spread of the disease.

How 2019-nCoV Spreads

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.

Signs and symptoms

As with other respiratory illnesses, infection with 2019-nCoV can cause mild symptoms including a runny nose, sore throat, cough, and fever.  It can be more severe for some persons and can lead to pneumonia or breathing difficulties.  More rarely, the disease can be fatal. Older people, and people with pre-existing medical conditions (such as, diabetes and heart disease) appear to be more vulnerable to becoming severely ill with the virus.

CDC real time Tests for COVID-19

CDC has developed a new laboratory test kit for use in testing patient specimens for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19. The test kit is called the “Centers for Disease Control and Prevention (CDC) 2019-Novel Coronavirus (2019-nCoV) Real-Time Reverse Transcriptase (RT)-PCR Diagnostic Panel.” It is intended for use with the Applied Biosystems 7500 Fast DX Real-Time PCR Instrument with SDS 1.4 software. This test is intended for use with upper and lower respiratory specimens collected from persons who meet CDC criteria for COVID-19 testing. CDC’s test kit is intended for use by laboratories designated by CDC as qualified, and in the United States, certified under the Clinical Laboratory Improvement Amendments (CLIA) to perform high complexity tests. The test kits also will be shipped to qualified international laboratories, such as World Health Organization (WHO) Global Influenza Surveillance Response System (GISRS) laboratories. The test will not be available in U.S. hospitals or other primary care settings. The kits will be distributed through the International Reagent Resource (IRR).

Prevention

There is currently no vaccine to prevent 2019-nCoV 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:
  • Avoid close contact with people who are sick.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
  • 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.
  • Follow CDC’s recommendations for using facemask.
    • CDC does not recommend that people who are well wear facemask to protect themselves from respiratory viruses, including 2019-nCoV.
    • Facemask should be used by people who show symptoms of 2019 novel coronavirus, in order to protect others from the risk of getting infected. The use of facemasks is also crucial for health workers and people who are taking care of someone in close settings (at home or in a health care facility).
  • 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.

Treatment

There is no specific antiviral treatment recommended for 2019-nCoV infection. People infected with 2019-nCoV should receive supportive care to help relieve symptoms. For severe cases, treatment should include care to support vital organ functions. People who think they may have been exposed to 2019-nCoV should contact your healthcare provider immediately.

Antibiotics do not work against viruses, they only work on bacterial infections. The novel coronavirus is a virus and, therefore, antibiotics should not be used as a means of prevention or treatment.

The Coronaviruses (CoV)


Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans. 
Coronaviruses are zoonotic, meaning they are transmitted between animals and people.  Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
