How is COVID-19 transmitted?
The coronavirus (SARS-CoV-2) causing COVID-19 is mainly transmitted between people via respiratory droplets or secretions from the respiratory tract. Transmission via droplets happens when an infected person coughs or sneezes and the droplets reach mucous tissue in someone's eyes, nose, or mouth. The droplets fall to the ground within approximately one meter (3 ft) from the source.
The virus can be transmitted via contaminated surfaces, so-called indirect contact transmission, but the risk of getting infected via contaminated surfaces is considered to be very low. There are no indications that anyone has been infected with the new coronavirus from touching contaminated surfaces or items.
Can COVID-19 be transmitted from a person who is infected but does not experience any symptoms?
The coronavirus causing COVID-19 (SARS-CoV-2) is mainly transmitted person-to-person via respiratory droplets. This means that the virus reaches the inside of your eyes, nose or mouth from droplets that are dispersed in the air when someone sneezes or coughs. The droplets fall to the ground within approximately one meter (3 ft) from the source.
There are reports of transmission of COVID-19 from people without any symptoms of illness. However, only a few studies describe the role of this type of transmission in relation to the overall spread of COVID-19 in the community. Based on the available knowledge about COVID-19 and similar diseases, the current understanding is that this route of transmission represents a minor part.
Do I need to clean my house or handle household waste in any particular way?
In a household where someone is ill with COVID-19 it is enough to clean as usual, using products available in supermarkets. Household waste, including paper tissues from infected persons, can be disposed of in your normal way.
What is your advice regarding face masks?
We do not currently recommend face masks in public settings since the scientific evidence around the effectiveness of face masks in combatting the spread of infection is unclear. However, there may be situations where face masks can be useful despite the uncertain state of knowledge about the effects.
Why are countries acting differently over face masks?
The scientific evidence around the effectiveness of face masks in combatting the spread of infection is weak, which is why different countries have arrived at different recommendations.
Some countries have chosen to view face masks as a form of security and hope that universal use of face masks will reduce the risk of infection spreading from people who are in the incubation period, before the symptoms are apparent, or who have such mild or unspecific symptoms that they do not consider themselves ill.
The Public Health Agency of Sweden does not recommend the general use of face masks, as a face mask that itches or slips down below the nose may mean a person is regularly touching their mouth, eyes or nose with their hands, which can increase the risk of the infection spreading.
Use of a facemask may also encourage people with mild symptoms to go out into the community, which might increase the spread of infection.
If one person in a family is ill, does the whole family need to stay at home?
No, as long as siblings or other members of the family do not show symptoms of disease they can go to school, preschool or their workplace. In families where one or more people are ill, it is very important to be alert to any signs of illness.
Why are universities and colleges only offering distance learning?
As of 15 June 2020 the recommendation ends for upper secondary schools, colleges, universities, and other institutions of higher education or adult learning to provide distance education rather than classes on their premises.
The reason is that children and youth to a limited extent have been diagnosed with COVID-19 and few have been in need of intensive care. In the light of current knowledge upper secondary schools, colleges, universities, and other institutions of higher education or adult learning may resume classes on their premises.
I’ve tested positive for antibodies. What are the implications?
For anyone who has no symptoms, the presence of IgG antibodies means they are less at risk of being infected and thus, there is less of a risk that they will pass on the infection to other people.
If you have no symptoms, a positive test result allows you greater opportunities to socialise with other people, even if you are in an at-risk group or are aged 70 or over. In the first place, this could mean socialising with people you are close to, such as friends and family, both indoors and outside.
Why are schools and pre-schools not closed in Sweden?
The Public Health Agency does not currently consider it necessary to close all schools in Sweden. There are no scientific evidence indicating that such an intervention would have any significant impact on the pandemic, nor has any major transmission of COVID-19 in schools been reported.
Closing schools and pre-schools would have a negative impact on society. For example, essential workers to the public (e.g. healthcare staff) would need to stay at home with their children. It could also put vulnerable groups, such as grandparents, at risk if they help out with childcare.
