A new United Kingdom -based study has found that the majority of people who were previously infected with COVID-19 have very high levels of antibodies for six months or more following an initial infection, possibly protecting them from a second infection for that time period.
There are no new community cases.
One of the infected cases announced today is linked to shore leave in New Zealand.
Among 1,700 people who tested positive for a previous COVID-19 infection, 99% had antibodies for 3 months.
The ministry added that her case may be reclassified as an imported case, as her serology test result is pending.
Singapore has had 29 deaths from Covid-19 complications, while 15 who tested positive have died of other causes.
The doctors say patients are presenting with symptoms that would traditionally be dismissed as a regular, common cold - before testing positive for covid. They will be tested at the start and end of their quarantine to detect asymptomatic cases.
On Wednesday, Reuters reported that Naomi Allen, professor and chief scientist at the U.K. Biobank - where the study was carried out - said that long-lasting antibodies prompt researchers to believe reinfection during that period of time will be rare. "Our total number of confirmed cases is 1952". "We thank all New Zealanders for their efforts to scan, scan, scan", the Health Ministry said in a statement.
However, Director-General of Health Dr Ashley Bloomfield and Medsafe Group Manager Chris James will speak to media about plans for New Zealand's Covid-19 at 2.45pm.
The Pullman Hotel is now being emptied of guests, while an investigation continues into identifying the source of the outbreak which saw four people staying on the same floor contract Covid in January.
The infections involve seven events across five facilities.
All are in managed isolation - one in Auckland, one in Christchurch, and one on a ship.
But they did not include the 13 global mariners staying in a Christchurch managed isolation facility, who were thought to have contracted Covid-19 overseas. New cases and hospitalisations have come down significantly in recent weeks.
The remaining imported case was a sea crew member holding a Special Pass who arrived from Indonesia to board a vessel docked here.
