COVID-19

  • "Coronavirus disease 2019 (COVID-19)" is the disease caused by a new coronavirus called SARS-CoV-2.

  • The most common symptoms of COVID-19 include fever, dry cough and fatigue. Other symptoms include loss of taste or smell, nasal congestion, conjunctivitis, sore throat, headache, muscle or joint pain, skin rash, nausea or vomiting, diarrhoea, chills or dizziness. Some people may only have very mild or non-specific symptoms, while some may develop severe symptoms like shortness of breath, chest pain or confusion.

  • Complications may include respiratory failure, acute respiratory distress syndrome (ARDS), sepsis and septic shock, thromboembolism, and/or multi-organ failure including injury of the heart, liver or kidneys

  • People of older age and those with underlying medical problems (e.g. hypertension, heart and lung problems, diabetes, obesity or cancer) are at higher risk of developing serious illness.

  • Some people who have had COVID-19 may continue to experience symptoms, including fatigue, respiratory and neurological symptoms. At the moment, it is still unclear how long the symptoms may last.

  • The main mode of transmission is through respiratory droplets, the virus can also be transmitted through contact. Most estimates of the incubation period range from 1 to 14 days, most commonly around 5 to 6 days.

  • COVID-19 vaccines are effective to protect people from developing COVID-19 disease.

  • Vaccination is one of the tools in the overall public health response to COVID-19. The combination of non-pharmaceutical interventions (NPIs) with vaccination will allow for maximum protection against the virus.

  • With COVID-19 vaccines deployed, there is a need to continue NPIs, including social distancing, good hand hygiene and wearing a mask in public, to reduce the risk of virus transmission. NPIs should continue to be followed by vaccinated individuals, as well as those who have not yet been vaccinated.
