Understand the coronavirus 2019 (COVID-19)

No country is immune to the spread of coronavirus. The disease it causes was officially named COVID-19 by the World Health Organization (WHO). The outbreak has been declared a global public health emergency. Here’s all you need to know to stay healthy!

Looking back, the fast-spreading virus was first detected in Wuhan City, in the Hubei Province of China in December 2019. It has since spread to multiple countries, with Egypt recording the first case on the African continent on Valentine’s Day (the case tested negative for COVID-19 and underwent a 14-day observation period until 27 February 2020). Algeria’s health ministry confirmed a COVID-19 case on 25 February 2020. And Nigeria’s health ministry confirmed their first case on 28 February 2020. Only a day earlier the South African Presidency announced that 132 South Africans, currently living under lockdown, would be evacuated from Wuhan city. Although none of them were diagnosed with or had symptoms of COVID-19, they would be placed in quarantine for 21 days on arrival in South Africa as a precautionary measure.


What makes COVID-19 so tricky to deal with?

“There is limited information available about its clinical features and severity of disease it causes,” says Dr Noluthando Nematswerani, Discovery Health’s Head of the Centre for Clinical Excellence. “Recent data shows that more than 80% of people infected with COVID-19 have mild disease and recover. In about 5% of cases patients have critical disease and in 3.4% of cases the virus causes a fatal respiratory illness. The risk of death increases the older a person is. While, scientists scramble to develop a vaccine for COVID-19, international efforts are concentrated on early detection and quarantining infected patients.”

How well do you understand novel coronavirus 2019?

COVID-19 spreads very quickly through:

  • The air, after coughing or sneezing – people could catch COVID-19 if they are standing within one meter of a person who has the illness, by breathing in particles coughed out or exhaled by the ill person
  • Close personal contact, such as when shaking hands or touching others
  • Touching an object or surface on which the virus is found (after an ill person coughs or exhales close to these objects or surfaces such as desks, tables or telephones), then – before washing the hands – touching their mouth, nose, or eyes

People who contract COVID-19 may take anywhere from one to 14 days to develop symptoms. There is no medicine available to combat the virus during the asymptomatic phase. Symptoms of COVID-19 include:

  • Fever
  • Cough
  • Shortness of breath or difficulty breathing

Other symptoms can include:

  • Tiredness
  • Aches
  • Chills
  • Sore throat
  • Loss of smell
  • Headache
  • Severe vomiting

Doctors can only treat the symptoms of COVID-19 as they present. No specific therapy has been shown to be effective against the virus itself.

Spreading a prevention message stops the spread of viruses

The following eight simple, powerful habits provide protection against coronaviruses, flu viruses and many other pathogens that are common in South Africa and abroad.  

  1. Wash your hands often, especially after direct contact with people who are ill, or after being in environments where sick people are cared for, like hospitals. Remember to wash your hands with soap and water for at least 20 seconds – even if they are not visibly dirty.
    • Read all about the right way to wash your hands here.
  2. Avoid close contact with people who have acute respiratory tract infections
  3. Avoid touching your eyes, nose, and mouth with unwashed hands
  4. Practice cough etiquette: when you cough, maintain your distance from others. Cover your mouth and nose with clothing, or with a flexed elbow or a tissue (discard it immediately) and wash your hands immediately afterwards
  5. Avoid spitting in public
  6. Clean and disinfect frequently-touched objects and surfaces
  7. Avoid eating raw or undercooked animal products. Handle raw meat, milk or animal organs with care to avoid cross-contamination with other uncooked foods. Use different cutting boards and knives for raw meat and other foods. Wash your hands between handling raw food – especially meat – and any other food.
  8. Do not eat the meat that comes from animals that have died of diseases

“If you feel ill and have any of the symptoms of infection with COVID-19 you must seek medical care early and share your previous travel history with your healthcare provider,” says Dr Nematswerani.

You will need to be tested for COVID-19 if you have:

  • A severe acute respiratory illness, with fever or history of fever and cough with pneumonia, or
  • Acute respiratory distress syndrome (based on clinical/X-ray findings) that requires you to be admitted to hospital
  • And any of the following:
    • Have a documented travel history to Wuhan, China within 14 days before symptom started, or
    • Have had close physical contact with a person confirmed to have COVID-19 while they are symptomatic
    • Are a healthcare worker who was exposed to patients with severe acute respiratory infections (in the absence of any other reason for your symptoms)

How do you stay healthy while travelling?

  • Frequently clean your hands with soap and water or alcohol-based hand sanitiser.
  • Avoid touching your eyes, nose or mouth with dirty hands while travelling, especially when using public transport
  • If you choose to wear a face mask, be sure to cover your mouth and nose and avoid touching the mask once it’s on. The WHO explains when and how to use medical masks.
  • Immediately discard single-use masks after each use and wash your hands after removing the mask.
  • Avoid close contact with people suffering from fever and cough.
  • Eat only well-cooked food.
  • Avoid contact with sick animals.
  • It’s important to avoid travel if you have a fever and cough. If you become sick while travelling on an airplane or using public transport, inform the personnel and seek medical care early. When you seek medical attention, remember to share your travel history with your healthcare provider
  • Avoid markets where live animals are sold. If you do visit animal markets in areas currently experiencing cases of COVID-19, avoid direct unprotected contact with live animals and surfaces in contact with animals. Avoid contact with stray animals, waste and fluids in roads and markets.
