Thailand reported a single day jump of 188 new confirmed COVID-19 cases, bringing the country’s total so far to 599, with most of the new cases concentrated in Bangkok.

Public Health Ministry spokesman, Dr. Thaveesilp Wissanuyothin, told a news conference that the new infections comprise two groups.

The first group of 65 cases includes 21 who are connected to boxing stadia in Bangkok, Loei, Nong Bua Lamphu, Udon Thani, Chon Buri, Phatthalung, Phra and Samut Prakan provinces. Five in the group are associated with entertainment businesses, two are related to religious affairs in Malaysia and 37 were in contact with infected people in Bangkok, Samut Prakan, Sukhothai, Songkhla, Khon Kaen and Udon Thani provinces.

The second group of 15 cases includes six Thai and two foreign students returning from abroad and seven working in entertainment venues, selling lottery tickets and selling goods at boxing stadia.

533 required hospital treatment, including seven severe cases, with 45 recoveries and one death.

Dr. Thaveesilp said that officials have tested tens of thousands of people, but only 4% proved positive for the virus.

He urged migrant workers and residents in Bangkok to refrain from moving out of Bangkok, because such movements may spread the contagion.

The Disease Control Department has instructed the Land Transport Department to order bus operators to screen passengers before boarding and to advise those with a fever to return to their lodgings. They should carry out social distancing on buses, cleanse buses before and after a trip and get basic contact information from the passengers such as their phone numbers.

The state-run Transport Company reported 12,889 bus trips and 178,333 passengers from Friday to Sunday.  The floors of bus terminals and hand rails are being disinfected on regular basis.

The State Railway of Thailand also reported fewer passengers than the average 70,000 per day. About 30,000 passengers on Saturday and about 50,000 passengers on Friday.
