What is COVID-19?
(Source: World Health Organization)
Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
The best way to prevent and slow down transmission is be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face.
The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).
Safe and reliable vaccines can help protect you and your family from Covid-19.
They are an important tool to help stop the spread of the virus. The Covid-19 vaccine does not cause an infection. It helps to build up your immunity to the virus, so your body will fight it off more easily if it affects you.
After independent and thorough scientific reviews for safety, efficacy and quality, Health Canada has approved four vaccines for use in Canada:
- Janssen (Johnson & Johnson)
To prevent infection and to slow transmission of COVID-19, do the following:
- Wash your hands regularly with soap and water, or clean them with alcohol-based hand rub.
- Maintain at least 2 metres distance between you and people coughing or sneezing.
- Avoid touching your face.
- Cover your mouth and nose when coughing or sneezing.
- Stay home if you feel unwell.
- Refrain from smoking and other activities that weaken the lungs.
- Practice physical distancing by avoiding unnecessary travel and staying away from large groups of people.
The COVID-19 virus affects different people in different ways. COVID-19 is a respiratory disease and most infected people will develop mild to moderate symptoms and recover without requiring special treatment. People who have underlying medical conditions and those over 60 years old have a higher risk of developing severe disease and death.
Common symptoms include:
- dry cough
Other symptoms include:
- shortness of breath
- aches and pains
- sore throat
- and very few people will report diarrhea, nausea or a runny nose.
