IEDCR and icddr,b jointly started Hospital-Based Rotavirus and Intussusception Surveillance (HBRIS) in 2012 with the technical support from United States Centers for Disease Control and Prevention (US-CDC). With the support of WHO, IEDCR took over HBRIS in 2019. Currently, it is running in 7 tertiary hospitals. The objectives of the surveillance system are to:

1. Describe the frequency of rotavirus-associated hospitalizations

2. Identify the circulating strains among children less than 5 years of age

3. Estimate the frequency of intussusception-related hospitalizations among children less than 2 years of age across the country (currently the intussusception surveillance is running for collecting baseline data)

4. Estimate changes in rates and ratios in rotavirus-associated hospitalizations after introduction of rotavirus vaccine in Bangladesh

5. Identify changes in strain diversity and detect any increase in patients seeking care for intussusception after the introduction of vaccine (intussusception was found as an adverse event of rotavirus vaccine administration in Malaysia in 2006. Thus in 2009, WHO suggested intussusception baseline surveillance in countries who are planning for rotavirus vaccine implementation).

N.B. The vaccine for the rotavirus is yet to be implemented in Bangladesh.

From 2012 to 2023 the proportion of rotavirus positivity showed a seasonal variation with upsurge in November to February with a peak in January (Fig 3).

Highlights:

• In 2023, 1,490 samples were tested of which 944 (63%) cases were positive for Rotavirus
