Spread of infection

    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.

    There is no data indicating that people have been infected from food or water. 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. It is also unlikely that COVID-19 is transmitted via water in swimming pools or other types of baths.

    Wash your hands often with soap and warm water; before cooking and eating and after using the toilet. Alcohol-based hand rub is an alternative when you do not have access to hand washing facilities.

    More information is available from the Swedish Food Agency (in Swedish).

  • Can the virus causing COVID-19 spread between animals and humans and can my pet get the virus?

    The virus causing the disease COVID-19 was most probably transmitted from animals to humans at a market with live animals in China. The possible animal source of COVID-19 has not yet been confirmed but research is ongoing.

    There are occasional reports that the infection can spread from humans to pets under certain circumstances, but the likelihood that this would occur is minute. The epidemic is driven by the spread of the virus between humans.

    More information is available from the National Veterinary Institute, SVA (in Swedish).

    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.

    Our general guidelines state that people should maintain a physical distance from other people to reduce the risk of spreading COVID-19, particularly outside their immediate circles. Closeness, intimacy and sex promote well-being and a general good state of health. In a steady relationship, where people are already seeing each other and are close, sex is not precluded provided you or your partner/s are not showing any symptoms of illness. However, dating and casual sexual relationships with new partners put you at risk of being infected or of infecting others.
