In rare cases, coronaviruses that infect animals can also infect people. Coronaviruses that cause disease in humans can be spread by close contact between people. Some viruses in the coronavirus family cause disease in animals, while others cause disease in humans. Furthermore, the World Health Organization (WHO) has stated that nothing indicates that coronavirus can be transmitted by mosquitoes. In QuГ©bec, there is no evidence to suggest that people are at risk of contracting COVIDвЂ‘19 from animals or animal products. Water treatment methods used in drinking water systems can neutralize the COVID-19 virus. You should continue to wash fruits and vegetables as usual and to follow good hygiene practices during food preparation. It mainly depends on the type of surface (for example, copper, cardboard, stainless steel, plastic), the temperature and ambient humidity.В According to findings from a recent experiment, the virus might be able to survive up to:ДЄt this time, there is no evidence to suggest that food is a likely source or route of transmission of COVID-19.

They can survive on surfaces for a few hours to several days. In general, coronaviruses do not survive more than a few hours or days on objects. Researchers are still studying this question. See the Covid-19 vaccination page for more information.Д¬urrent knowledge does not allow us to identify precisely when COVID-19 is transmitted, but it is believed that a person infected with COVIDвЂ‘19 may be contagious for 48 hours before symptoms appear. ThatвЂ™s why itвЂ™s important to keep following the usual protection measures (physical distancing, mask wearing, and hand washing). Even people who have been vaccinated may pass on the virus if they are infected with certain variants, such as the Delta variant or the Omicron variant. People can be infected by touching contaminated surfaces or objects, but this is not the main mode of transmission.Д¬ertain variants seem to be transmitted more easily than others. When there is close contact, the virus can be picked up by direct contact, through particles in the air, or by contact with a surface contaminated by respiratory particles from an infected person. However, it is hard to determine exactly how an infected person passes the virus to others.

Aerosols can be of different sizes and are emitted in variable quantities when the infected person breathes, talks, sings, coughs, sneezes, and so on. Transmission can occur through aerosols, which are fine particles suspended in the air, especially indoors. The virus that causes COVID-19 is transmitted mainly through close contact lasting more than 15 minutes at a distance of less than two metres. However, the risk of death is highest for people aged 70 and older. with a chronic disease such as diabetes or heart, lung and kidney disease.People most at risk of dying from complications are those: Some people can spreadВ the virus without knowing, even if theyвЂ™ve been vaccinated, because they have no symptoms or have not yet developed them. In severe cases, symptoms can last for over a month. Their duration varies depending on the severity of the illness, but they generally disappear in less than 14 days. Symptoms can be mild or more severe like those associated with pneumonia. Muscle aches (not related to physical exertion).Runny nose nasal congestion (stuffy nose) for no known reason.Sudden loss of smell with no nasal congestion, with or without loss of taste.Fever of 38.1вЊ (100.6вЏ) and over (oral temperature).Runny nose or nasal congestion (stuffy nose) for no known reason AND another symptom above.Stomach pain, vomiting or diarrhea AND moderate fever of 38.5вЊ (101.3вЏ) and over (rectal temperature).

Sore throat AND moderate fever of 38.5вЊ (101.3вЏ) and over (rectal temperature).

Cough (new or worsening), shortness of breath, trouble breathing.

Moderate fever of 38.5вЊ (101.3вЏ) and over (rectal temperature).

When in doubt, call Info-SantГ© 811 or see a healthcare professional. Same symptoms as for children age 6 months to 5 years. If you are unable to get rapid tests, self-isolate in accordance with Instructions for people with COVID-19. A screening test must be performed to identify the presence of COVID-19.В Due to an increase in the number of infections, PCR testing at the screening clinic is now reserved for certain higher priority clients.В If you are not in a priority group, it is recommended that you do a rapid test at home. It is impossible to distinguish between COVID-19 and the flu based solely on symptoms, because they are too alike.
