People could consider livestreaming funerals to allow others to be included. US cemeteries will otherwise be closed to the public until further notice.
Those sitting shivah cannot have visitors as “a gathering of people in a shivah house does not comply with government social distancing requirements”. Rabbis will not visit the shivah house and the US advises that those wishing to comfort mourners should phone or email.
Although the US had previously advised that weddings could be held in restricted circumstances, its now says they are “not possible at this time”.
Mikvaot remain open for women, but men are asked to refrain from going.
Members were reassured that "best-practice guidelines on hygiene and social distancing are in place at local mikvaot in North London".
US chief executive Steven Wilson said the new guidelines "reflect the United Synagogue's overwhelming priority to protect life.
"The coronavirus crisis has forced changes upon us we couldn't have imagined.
"No chief executive wants to have to limit attendance at funerals or tell families they have to postpone a stonesetting for a loved one.
"The Torah teaches that regarding mitzvot, 'v'chai bahem [you must live by them]', from which the Talmud learns that in certain circumstances, we have to postpone a mitzvah in order to save lives. This principle has been at the heart of all the careful actions the United Synagogue has taken so far in response to this crisis."
