COVID-19
Coronavirus

 

Coronaviruses are a large family of viruses which may cause illness in animals or humans.  In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.

 

COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019. COVID-19 is now a pandemic affecting many countries globally.

 

The most common symptoms of COVID-19 are fever, dry cough, and tiredness. Other symptoms that are less common and may affect some patients include aches and pains, nasal congestion, headache, conjunctivitis, sore throat, diarrhea, loss of taste or smell or a rash on skin or discoloration of fingers or toes. These symptoms are usually mild and begin gradually. Some people become infected but only have very mild symptoms.

Most people (about 80%) recover from the disease without needing hospital treatment. Around 1 out of every 5 people who gets COVID-19 becomes seriously ill and develops difficulty breathing. Older people, and those with underlying medical problems like high blood pressure, heart and lung problems, diabetes, or cancer, are at higher risk of developing serious illness.  However, anyone can catch COVID-19 and become seriously ill.  People of all ages who experience fever and/or  cough associated withdifficulty breathing/shortness of breath, chest pain/pressure, or loss of speech or movement should seek medical attention immediately. If possible, it is recommended to call the health care provider or facility first, so the patient can be directed to the right clinic.

 

If you have minor symptoms, such as a slight cough or a mild fever, there is generally no need to seek medical care. Stay at home, self-isolate and monitor your symptoms. Follow national guidance on self-isolation.

However, if you live in an area with malaria or dengue fever it is important that you do not ignore symptoms of fever.  Seek medical help.  When you attend the health facility wear a mask if possible, keep at least 1 metre distance from other people and do not touch surfaces with your hands. If it is a child who is sick help the child stick to this advice.

Seek immediate medical care if you have difficulty breathing or pain/pressure in the chest. If possible, call your health care provider in advance, so he/she can direct you to the right health facility.

 

People can catch COVID-19 from others who have the virus. The disease spreads primarily from person to person through small droplets from the nose or mouth, which are expelled when a person with COVID-19 coughs, sneezes, or speaks. These droplets are relatively heavy, do not travel far and quickly sink to the ground. People can catch COVID-19 if they breathe in these droplets from a person infected with the virus.  This is why it is important to stay at least 1 meter) away from others. These droplets can land on objects and surfaces around the person such as tables, doorknobs and handrails.  People can become infected by touching these objects or surfaces, then touching their eyes, nose or mouth.  This is why it is important to wash your hands regularly with soap and water or clean with alcohol-based hand rub.

WHO is assessing ongoing research on the ways that COVID-19 is spread and will continue to share updated findings.

 

If you have been in close contact with someone with COVID-19, you may be infected.

Close contact means that you live with or have been in settings of less than 1 metre from those who have the disease. In these cases, it is best to stay at home.

However, if you live in an area with malaria or dengue fever it is important that you do not ignore symptoms of fever. Seek medical help. When you attend the health facility wear a mask if possible, keep at least 1 metre distant from other people and do not touch surfaces with your hands. If it is a child who is sick help the child stick to this advice.

If you donotlive in an area with malaria or dengue fever please do the following:

  • If you become ill, even with very mild symptoms you must self-isolate
  • Even if you don’t think you have been exposed to COVID-19 but develop symptoms, then self-isolate and monitor yourself
  • You are more likely to infect others in the early stages of the disease when you just have mild symptoms, therefore early self-isolation is very important.
  • If you do not have symptoms, but have been exposed to an infected person, self-quarantine for 14 days.

If you have definitely had COVID-19 (confirmed by a test) self-isolate for 14 days even after symptoms have disappeared as a precautionary measure – it is not yet known exactly how long people remain infectious after they have recovered. Follow national advice on self-isolation.

 

If you choose to wear a mask:

  1. Before touching the mask, clean hands with an alcohol-based hand rub or soap and water
  2. Take the mask and inspect it for tears or holes.
  3. Orient which side is the top side (where the metal strip is).
  4. Ensure the proper side of the mask faces outwards (the coloured side).
  5. Place the mask to your face. Pinch the metal strip or stiff edge of the mask so it moulds to the shape of your nose.
  6. Pull down the mask’s bottom so it covers your mouth and your chin.
  7. Do not touch the mask while you are wearing it for protection.
  8. After use, take off the mask with clean hands; remove the elastic loops from behind the ears while keeping the mask away from your face and clothes, to avoid touching potentially contaminated surfaces of the mask.
  9. Discard the mask in a closed bin immediately after use. Do not reuse the mask.
  10. Perform hand hygiene after touching or discarding the mask – Use alcohol-based hand rub or, if visibly soiled, wash your hands with soap and water.

Be aware that there is a global shortage of medical masks (both surgical masks and N95 masks). These should be reserved as much as possible for health care workers.

Remember that  masks are not a substitute for other, more effective ways to protect yourself and others against COVID-19 such as frequently washing your hands, covering your cough with the bend of elbow or tissue and maintain a distance of at least 1 meter from others.

 

The time between exposure to COVID-19 and the moment when symptoms start is commonly around five to six days but can range from 1 – 14 days.

 

The most important thing to know about coronavirus on surfaces is that they can easily be cleaned with common household disinfectants that will kill the virus. Studies have shown that the COVID-19 virus can survive for up to 72 hours on plastic and stainless steel, less than 4 hours on copper and less than 24 hours on cardboard.

As, always clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.
