SINGAPORE - There was a surge in the number of Group B Streptococcus (GBS) infections earlier this year.

Public hospitals reported 238 cases of GBS infection in the first half of the year, up from an average of 150 cases in the last four years.

In July, Ministry of Health said it has found a link between the consumption of raw fish and GBS infection in a limited number of cases.

GBS is a bacteria which is commonly found in our gut and urinary tract without causing disease. GBS is also found in fish, but usually does not pose any risk.

Shortly after, the National Environment Agency issued an advisory to more than 70 raw fish porridge stalls asking them to temporarily stop selling raw fish dishes made from Song fish, or Asian bighead carp, and Toman fish, also called snakehead.

Here's a look at some of the GBS cases reported in the media, and what you need to know about the bacteria:
