Trưởng ban Y tế tiểu bang NSW Dr Kerry Chant cho biết để ngăn chặn sự lây lan trong cộng đồng, điều quan trọng là phải xác định được tất cả các trường hợp có tiếp xúc với người nhiễm Covid-19. Một trong những chuyên viên của Bộ Y Tế NSW làm công việc cần thiết đó là anh Kevin Huỳnh.
Contact tracing is a process used to understand how an infectious disease is spreading in a community. Contact tracing has two purposes: to figure out who a sick person caught an illness from, and to find out who they’ve been in contact with while infectious.
When a person is diagnosed with an infectious disease like coronavirus (COVID-19), contact tracing is used to figure out where they caught the virus and who they might have passed it on to.
Contact tracing is a process conducted by health professionals all around the world, and Kevin Huynh works for one of those specialist teams at NSW Health.
