Fourteen new COVID-19 cases were identified between Friday and Saturday, health authorities have said.
Nine of the new cases have been classified as asymptomatic - meaning patients exhibited no symptoms when they tested positive.
It is the third consecutive day in which the number of newly-detected coronavirus cases has reached double digits. Malta has now confirmed 546 cases of COVID-19.
The new cases were detected from 1,727 swab tests – a national one-day record number of tests.
Two further patients have recovered from the virus, meaning 450 patients have now overcome the infection. Healthcare professionals currently have 90 active cases in their care.
Three patients are currently at Boffa Hospital. Six are at St Thomas Hospital, two are at Mater Dei’s Infectious Diseases Unit and three are at Karin Grech Hospital.
The new figures were released, unannounced, by the Health Ministry via Facebook.
Superintendent for Public Health Charmaine Gauci provided more details about the new cases during her daily COVID-19 briefing.
The higher number of asymptomatic cases reflected the growing number of daily tests being carried out, she said.
Malta's R factor - the reproduction rate of the virus - has remained below 1 on average over the past week, with the odd spike, she said.
Gauci had said on Friday that the country's R factor stood at 1.3.
Anyone with COVID-19 symptoms should remain in isolation even if they test negative for the virus, Gauci emphasised, as they might be in the early stages of infection and not have a high enough viral load for the virus to be detected at that stage.
High-risk cases are tested twice over a number of days, to ensure there is no risk of a false negative test result, she said.
Antibody testing kits, which can determine whether a person has developed immunity to the COVID-19 virus, are still having their validity assessed, she said.
