A Hong Kong man who recovered from Covid-19 was infected again four and a half months later, in the first documented instance of human reinfection, researchers said on Monday.
The University of Hong Kong researchers said the case indicated that the disease, which has killed more than 820,000 people worldwide, may continue to spread among the global population despite herd immunity.
The man, 33, was cleared of Covid-19 and discharged from a hospital in April, but tested positive again after returning from Spain through Britain on August 15.
The patient appeared to be previously healthy, researchers said in the paper, which was accepted by the international medical journal Clinical Infectious Diseases.
Meanwhile, two European patients were also confirmed to have been reinfected with the coronavirus, regional public broadcasters said on Tuesday.
The cases raised concerns about people's immunity to the virus as the world struggles to tame the pandemic.
That has fuelled fears about the effectiveness of vaccines against the virus, although experts say there would need to be many more reinfections for these to be justified.
Broadcasters said on Tuesday that a patient in the Netherlands and another in Belgium were reinfected with the virus.
Elsewhere, British Prime Minister Boris Johnson said on Tuesday he was "really pleased" by the work teachers had done in preparing to reopen schools from next week.
Mr Johnson, whose Conservative government has come under fire for how it has tackled education during the coronavirus crisis, said it was "crucial" for all children to return to school.
He said he would look at medical evidence to see whether he should change the government's advice on wearing face masks.
"I'm really pleased by the work that teachers, schools, parents, pupils have done to get ready," Mr Johnson said on a visit in south-west England.
And in Australia, the government will spend A$1 billion ($716.80 million) to upgrade defence facilities, offer additional paid employment to army reservists and upgrade military vehicles.
Prime Minister Scott Morrison will make the announcements on Wednesday, as Canberra seeks to support its defence industry.
Australia has reported far fewer cases of Covid-19 than other developed countries, but restrictions imposed to slow the spread have had a devastating impact on the country's economy, which will slip into a recession for the first time in three decades.
In Japan, Tokyo Governor Yuriko Koike said on Tuesday that the coronavirus situation in the capital was improving and she was still intent on the city hosting the Olympics next year.
"I think the situation is much better than before," Ms Koike said.
"We will do our best to prevent coronavirus infections here in Japan and to welcome the athletes from all over the world."
She said last month that Tokyo could declare a state of emergency if the coronavirus situation deteriorated.
Daily cases had soared past 400 a day amid increased testing.
New cases have trended lower in the past week, and were at 187 in Tokyo on Tuesday.
Ms Koike said Tokyo had established many concrete measures to combat contagion, but the arrival and distribution of effective vaccines is an "essential factor" that has to be determined before the Games can go ahead.

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.

The language of diplomacy in 1853
Treaty of Peace in Perpetuity Agreed Upon by the Chiefs of the Arabian Coast on Behalf of Themselves, Their Heirs and Successors Under the Mediation of the Resident of the Persian Gulf, 1853
(This treaty gave the region the name “Trucial States”.)
We, whose seals are hereunto affixed, Sheikh Sultan bin Suggar, Chief of Rassool-Kheimah, Sheikh Saeed bin Tahnoon, Chief of Aboo Dhebbee, Sheikh Saeed bin Buyte, Chief of Debay, Sheikh Hamid bin Rashed, Chief of Ejman, Sheikh Abdoola bin Rashed, Chief of Umm-ool-Keiweyn, having experienced for a series of years the benefits and advantages resulting from a maritime truce contracted amongst ourselves under the mediation of the Resident in the Persian Gulf and renewed from time to time up to the present period, and being fully impressed, therefore, with a sense of evil consequence formerly arising, from the prosecution of our feuds at sea, whereby our subjects and dependants were prevented from carrying on the pearl fishery in security, and were exposed to interruption and molestation when passing on their lawful occasions, accordingly, we, as aforesaid have determined, for ourselves, our heirs and successors, to conclude together a lasting and inviolable peace from this time forth in perpetuity.
