Are the deceased COVID19 cases still infectious and for how long?

According to the Health Protection Surveillance Centre: 

The guidance document for funeral directors has stated it “is possible that the act of moving a recently deceased individual might be sufficient to expel a very small amount of air and viral droplet from the lungs and thereby present a minor risk.  

After death, the human body does not generally create a serious health hazard for COVID-19 infection.  

In the interests of infection control, all staff should use Standard Precautions as a matter of course, treating all human remains as though potentially infected.”
