An important update has been released by the NHS following the outbreak of a contagious bacterial infection known as invasive Group A streptococcal (iGAS). The deadly infection, which is believed to have started in Braintree, Essex, killed 13 people. The most up to date figures indicate that 35 people have been affected by the outbreak in total in Essex, with 32 confirmed cases and three probable. A statement from the NHS said: “As of July 30, there have been no further cases of iGAS and the total number of people affected by the iGAS outbreak is unchanged at 35.
“However following tests by Public Health England, the mid Essex patient whose results were pending last week has now been confirmed as a part of this outbreak.
“This means that of the 35 people affected by iGAS, 32 are confirmed as part of this outbreak and three are probable cases. Thirteen people have sadly died.”
Commenting on the incident at the start of the outbreak, Dr Jorg Hoffman, deputy director of health protection for PHE East of England, described it as “a very serious situation”.
He said: “This is still an ongoing outbreak. Unfortunately we have so far not been able to fully contain the situation.
“Obviously we are hoping that the efforts of our colleagues in the NHS and provider organisations are now bearing some fruit and we will be able to contain the situation and prevent further cases from happening.
“I cannot deny that there is still an ongoing risk until we can declare that this outbreak is over.”
