Indonesia's tourism minister on Monday said quarantine requirements for overseas visitors entering the country will end two years after border restrictions were imposed.

Tourism and Economy Minister Sandiaga Uno told reporters that foreign tourists will still be required to have a negative PCR test before entering the country.

Quarantine requirements will be lifted from Tuesday, he added.

Indonesia had already implemented a two-week trial of quarantine-free travel in Bali, Batam and Bintan islands, where coronavirus numbers have been falling.

The government is hoping the easing of travel restrictions will boost the number of foreign tourist this year to more than three million.

This month, Indonesia also lifted the negative COVID-19 test result as a requirement for domestic flights.

Indonesia reported on Monday 4699 new coronavirus infections and 154 deaths in the last 24-hour period.

Case numbers have dropped by more than 90 per cent from their peak in mid-February.

Despite having the lowest vaccination rate in the European Union, Bulgaria has decided to lift the requirement for people to produce proof of vaccination, recovery or a recent negative test when attending certain events, shopping in malls or eating in restaurants.

About 29.5 per cent of the population are fully vaccinated against the coronavirus, and 10.1 per cent have also had a booster shot.

Medical professionals have already expressed concern at the worrying drop in demand for new vaccinations that followed the government announcement that its so-called "green certificates" would be abolished.

The easing of restrictions has been justified by the stable decline in COVID-19 case numbers in Bulgaria.

The seven-day incidence currently stands at 166.6 per 100,000 people - less than a tenth of the German figure.

Mask mandates in supermarkets or on public transport are likely to remain in place, however, although face covering is frequently overlooked and is hardly ever checked.
