^†Rotavirus sampling sites and testing (method for G typing specified) and dates from the individual studies of the 6 Asian countries were as follows: In China, samples were collected from 3 sentinel hospitals in mainland China and tested (multiplex seminested reverse transcription polymerase chain reaction [RT-PCR]) from January 2006 to December 2007.¹⁶ In Hong Kong, samples were collected and tested (nested RT-PCR) from a microbiology laboratory of an acute public hospital and a government virology laboratory serving various regions over 1 year, from December 2001 to November 2002.¹⁷ In India, samples were collected from 10 representative hospitals in 7 different cities and tested (RT-PCR) at 4 laboratories in different parts of India from December 2005 to November 2007.¹⁸ In South Korea, samples were collected and tested (1-step RT-PCR) from 8 hospitals located in 3 metropolitan areas and 4 provincial regions from April 2005 to March 2007.19 In Taiwan, samples were collected from 3 sentinel hospitals in northern, central, and southern Taiwan and testing (1-step real-time RT-PCR) was conducted at the Centers for Disease Control and Prevention in Taiwan from January 2005 to December 2007.¹⁹ In Thailand, samples were collected from 6 general hospitals located throughout Thailand and tested (2-step PCR) at the Thai National Institutes of Health from 2001 to 2003 and from a community-based surveillance program from September 2001 to August 2002.
