Is it necessary for Bangladesh to isolate China in August 2022?

Need. According to relevant reports, the State Council issued the Prevention and Control Plan of novel coronavirus (9th Edition), which adjusted the control time of close contacts and entry personnel from "14 days of centralized isolation medical observation +7 days of home health monitoring" to "7 days of centralized isolation medical observation +3 days of home health monitoring". So in August, 2022, we will be isolated from Bengal to China.
