The head of the World Health Organization has tested positive for coronavirus and remains in quarantine, Your Content is learning.

WHO Director-General Tedros Adhanom Ghebreyesus said on Sunday that he had been identified as a contact of someone who tested positive for COVID-19, but added that he was feeling well and did not have any symptoms.

“I have been identified as a contact of someone who has tested positive for #COVID19. I am well and without symptoms but will self-quarantine over the coming days, in line with @WHO protocols, and work from home,” Tedros said in a tweet.

Coronaviruses are a large family of viruses that can cause illness in animals or humans. In humans there are several known coronaviruses that cause respiratory infections. These coronaviruses range from the common cold to more severe diseases such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and COVID-19.

COVID-19 was identified in Wuhan, China in December 2019. COVID-19 is caused by the virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a new virus in humans causing respiratory illness which can be spread from person-to-person. Early in the outbreak, many patients were reported to have a link to a large seafood and live animal market, however, later cases with no link to the market confirmed person-to-person transmission of the disease. Additionally, travel-related exportation of cases has occurred.


COVID-19 is primarily transmitted from person-to-person through respiratory droplets. These droplets are released when someone with COVID-19 sneezes, coughs, or talks. Infectious droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. A physical distance of at least 1 meter (3 ft) between persons is suggested by the World Health Organization (WHO) to avoid infection, although some WHO member states have recommended maintaining greater distances whenever possible. Respiratory droplets can land on hands, objects or surfaces around the person when they cough or talk, and people can then become infected with COVID-19 from touching hands, objects or surfaces with droplets and then touching their eyes, nose, or mouth. Recent data suggest that there can be transmission of COVID-19 through droplets of those with mild symptoms or those who do not feel ill. Current data do not support long range aerosol transmission of SARS-CoV-2, such as seen with measles or tuberculosis. Short-range inhalation of aerosols is a possibility for COVID-19, as with many respiratory pathogens. However, this cannot easily be distinguished from “droplet” transmission based on epidemiologic patterns. Short-range transmission is a possibility particularly in crowded medical wards and inadequately ventilated spaces. Certain procedures in health facilities can generate fine aerosols and should be avoided whenever possible.

Despite the important concerns about case fatality rates, most COVID-19 illnesses are – and we expect will continue to be – mild, and most patients will recover spontaneously with some supportive care, especially children and young adults. Data from several countries suggest that 14%-19% are hospitalized and 3%-5% will need intense care unit admission.

The first largest description of patients with COVID-19 came from China, where the outbreak of COVID-19 started, and is described in detail below.  Among the 44,672 confirmed COVID-19 cases reported from December 31, 2019 through February 11, 2020, the clinical presentation was as follow:

Mild (non-pneumonia and mild pneumonia cases) represented 80.9% of confirmed patients with COVID-19 in China.

NOTE: These cases included a large spectrum of illnesses including but not limited to patients having fever, cough, chest pain, nausea, and body pain. Severe (dyspnea, respiratory frequency ≥ 30/min, blood O2 sat ≤93%, PaO2/FiO2 ratio <300, lung infiltrates >50% within 24–48 hours) represented 13.8% of confirmed patients with COVID-19 in China.

Critical (respiratory failure, septic shock, and/or multiple organ dysfunction or failure, death) represented 4.7% of confirmed patients with COVID-19 in China. 1,023 (49%) deaths were reported among the 2,087 critically ill patients.

People at Higher Risk for Severe Illness

It is important to note that COVID-19 is a new disease, therefore there is limited information regarding risk factors for severe disease. In some cases, people who get COVID-19 can become seriously ill and develop difficulty breathing. These severe complications can lead to death. The risk of severe disease increases steadily as people age. Additionally, those of all ages with underlying medical conditions (including but not limited to heart disease, diabetes, or lung disease) appear to be at higher risk in developing severe COVID-19 compared to those without these conditions. As more data become available, additional risk factors for severe COVID-19 may be identified.

COVID-19: Everyday Preventive Actions

There are a number of ways to prevent the spread of COVID-19 infection. These include:

  • Avoid touching your eyes, nose and mouth
  • Avoid close contact with people who are sick
    • Remember that some people without symptoms can still spread the virus
  • Stay at home when you are sick
  • Cover your cough or sneeze with a tissue, then dispose of it properly
  • Use a face covering when physical distancing is difficult or when going into closed spaces
    • Physical distancing should be at least 1 meter (3 ft)
  • Clean and disinfect frequently touched objects and surfaces
  • Perform hand hygiene with soap and water or use alcohol-based hand rub
    • Hand Rub should contain at least 60% alcohol
    • Hand washing should be done for at least 40-60 seconds based on WHO’s recommendations

COVID-19: Treatment

Currently, care for patients with COVID-19 is primarily supportive. Care is given to patients to help relieve symptoms and manage respiratory and other organ failure. There are currently no specific antiviral treatments licensed for COVID-19, however many treatments are under investigation. Remdesivir, which is also an investigational drug, received Food and Drug Administration (FDA) emergency use authorization for treatment of hospitalized patients. Finally, no vaccine is currently available.
