There are also no published reports of transmission from giving or receiving oral or anal sex.
At the height of the pandemic last year, Canada’s chief public health officer Dr Theresa Tam advised new couples to consider wearing a face mask and avoid kissing during sex.
Tam said the lowest-risk sexual activity during Covid-19 “involves yourself alone”.
“Sexual health is an important part of our overall health,” she said in a statement.
“However, sex can be complicated in the time of Covid-19, especially for those without an intimate partner in their household or whose sexual partner is at higher risk for contracting the virus.
“Like other activities during Covid-19 that involve physical closeness, there are some things you can do to minimise the risk of getting infected and spreading the virus,” said Tam.
