According to the World Health Organization (WHO, 2020) Coronaviruses are a large group of viruses found in both animals and humans. Some of these viruses infect people and can cause illnesses ranging from the common cold to much more severe diseases, including Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).
Most recently in the news have been reports of a novel coronavirus, now called 2019-nCoV, that was first identified in Wuhan, China on December 31, 2019. The outbreak began with a cluster of pneumonia cases. Those patients were associated with seafood and live animal market in Wuhan. The virus quickly spread to family members and healthcare staff.
This is an extremely serious and highly contagious virus that in less than 2 months is affecting 28 countries and is still spreading rapidly. As of February 12, 2020:
There are 60,414 coronavirus cases
8,043 of these are patients in critical condition
There have been 1,370 deaths
Only 6,295 have recovered so far
While it doesn’t appear to be as deadly as the SARS virus in 2002-2003 it already has exceeded the number of people infected partly for that reason and because the incubation period is longer.
SARS (SARS-CoV, or Severe Acute Respiratory Syndrome), identified in 2002 and was resolved in 2004, was thought to originate in bats and spread to other animals. It affected more than 8000 people in 26 countries. MERS (MERS-CoV – Middle East Respiratory Syndrome) was first reported in Saudi Arabia in 2012 and remains in circulation in camels. There have been 2,494 cases reported and 858 associated deaths in 27 countries.
Currently, the exact source of the novel coronavirus (2019-nCoV) is unknown but public health officials are working to identify the source. There have already been over 60,000 infected and 1,300 deaths in at least 28 countries. Numbers change daily. There have also been cases reported that were a result of human-to-human transmission. Public health officials are clearly concerned and are monitoring the epidemiology of the outbreak.
|Novel Coronavirus Compared to Other Major Viruses|
Symptoms of Coronavirus
- Sore throat
- Shortness of breath
The incubation period ranges from 2 to 14 days, and the virus is transmittable even before those carrying the virus are showing any symptoms. That means carriers could be spreading the virus before they have any suspicion of having it themselves. If you do become sick, especially after traveling or being near someone who has, it is important you share your travel history with your medical provider.
The coronavirus can result in symptoms as mild as a common cold to very severe, including:
- Kidney failure
The coronavirus cannot be cured. All doctors can do for patients who are infected is to give them supportive care to help relieve their symptoms.
- Patients are separated from other family members if they are not needing hospital-stay treatment and recovering at home
- Patients and those near them need to use protective equipment (gloves, facemask, etc.)
- Elder adults, young children, pregnant women, and people who are immunocompromised or with chronic heart, lung, or kidney conditions are kept isolated from patients
The coronavirus is an extremely serious health threat. There is currently no vaccine to prevent or cure this virus, so prevention is key. Standard hygiene measures are important, especially if you believe you have been exposed to someone who may be sick.
- Stay informed
- Remain alert for subjective fever, cough, or difficulty breathing
- Certain occupational groups (e.g., some healthcare or laboratory personnel, airline crew members) should exercise extreme caution around those who have been exposed to this virus
- Follow travel advice of health officials
- Protect your health by seeking medical care early if you suspect you have been exposed to 2019-nCoV
The CDC recommends the following:
- 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
