Eleven people in Singapore have been investigated for the avian flu virus H7N9 and another 24 for novel coronavirus to date.
But none was positive.
Health Minister Gan Kim Yong, who revealed this in Parliament on Monday, said that so long as there is no sustained human-to-human transmission of the two diseases, the risk of an outbreak in Singapore will remain low.
Mr Gan said the H7 avian influenza virus has not been detected in tests on local and imported birds.
Singapore also does not import live poultry, birds or frozen poultry meat from China.
