The Centre for Covid-19 Situation Administration (CCSA) has been taking urgent measures after an Egyptian soldier confirmed to be infected with Covid-19 was found to have visited shopping malls in Rayong province.

Meanwhile, the family of a nine-year-old Thai girl infected with Covid-19 is being investigated after its members were found to not be in embassy accommodation, having stayed in a condominium.

Deputy Public Health Minister Sathit Pitutecha will visit Rayong on Tuesay while a deputy director-general of the Department of Disease Control will visit a condominium in Bangkok.

The visitors from Egypt stayed in Rayong before and after a one-day trip to China, where they had military business.

All were allowed to enter the country, says the CCSA, as they were defined as air crew under the conditions set by the Civil Aviation Authority of Thailand. They were not asked to quarantine because they were coming for less than 14 days but they were required to undergo virus tests.

The general manager of U-Tapao airport claimed only one member of the group, a soldier, sneaked out to visit shopping centres.

Many social media users urged authorities to reveal exactly which locations had been visited by the infected man.

The page said people had the right to know in order to protect themselves. 

Mr Sathit said later on Monday he would visit Rayong and check locations including Central department store, Laem Thong shopping mall and D Varee Diva Central Rayong Hotel.

Central on Monday announced it had checked and no Covid-19-infected patients visited the mall while the hotel said it had been informed by the Egyptian embassy that the group had passed Covid screening.

The health scare follows a positive result returned from the lab on Sunday after tests on a swab taken from the 43-year-old soldier. 

Authorities would also improve the screening at the airport in Rayong, which was not as strict as Suvarnabhumi airport. 

On Saturday, the CCSA also reported that a nine-year-old Thai girl who returned home from Sudan with her family had tested positive.

Dr Taweesilp said on Monday she had been hospitalised but the other four family members had not been quarantined because they were the family of a diplomat. They had reportedly self-isolated at a condominium in Bangkok, which the CCSA did not name.

The mother took everyone to get tested in Sudan last Tuesday before they left home, said Dr Taweesilp, and all tested negative.

Three days later, they were tested on arrival and the results were negative but more comprehensive tests showed the girl was infected.
