Thailand on Tuesday reported five new coronavirus cases, all quarantined returnees from Egypt, Japan and Sudan, raising the total to 3,255.
No new deaths were reported, leaving the accumulated death toll at 58.
Tuesday marked the 57th consecutive day with no locally transmitted infections.
No additional Covid-19 patients were discharged in the previous 24 hours, leaving the total number recovered at 3,096, with 101 people now hospitalised.
Taweesilp Visanuyothin, spokesman of the Centre for Covid-19 Situation Administration, said one new case was a male student aged 26 who arrived from on Japan on July 7.
He had a fever and was sent to a hospital in Samut Prakan province right away. His first test was negative but the second returned positive on Saturday. The disease was detected after he lost his sense of smell after he had been in hospital for about 10 days, Dr Taweesilp said.
Three of the new cases are male students aged 20, 25, and 28. They arrived on the same flight from Egypt on July 8. Eight others from the same flight were earlier confirmed as Covid-19 cases. The new cases were quarantined in Chon Buri province and tested positive on Sunday while being asymptomatic.
The other new case came from Sudan on Saturday. The 35-year-old man had hernia pain and was sent to hospital. He underwent a Covid-19 test the same day and it returned positive. He had no coronavirus symptoms, Dr Taweesilp said.
He said 500 Thai people had returned from Sudan and 23 of them had Covid-19, while 780 came from Egypt and 22 of them carried the disease. Four out of 1,983 returnees from Japan tested positive.
Global Covid-19 cases rose by 210,881 over the past 24 hours to 14.85 million. The death toll went up by 4,311 to 613,213. The United States had the most cases at 3.96 million and the most deaths at 143,834.
"The disease is still in its critical stage. With the increment of some 200,000 a day, 1 million new cases will be logged in five days. So, the total should reach 15 million tomorrow," Dr Taweesilp said.
Thailand ranked 102nd in the world by total number of cases.
