Please can you provide a breakdown of the number of different cases of infectious diseases in London each year since May 2016?

As the GLA does not collect data on all STI diagnoses in London, beyond those that are captured in GLA data store and that support specific areas of the Health Inequalities Strategy (HIS).  I must therefore refer the Assembly Member to our statutory health advisor Professor Paul Plant at Public Health England who will be able to provide the breakdown required.

My HIS refers explicitly to HIV, TB and hepatitis C because of the specific challenges they present in London, including the inequalities and stigma associated with them that can act as a barrier to early diagnosis.  I am supporting partnership efforts to eliminate hepatitis C by 2025 and new HIV infections by 2030.  A number of commitments in my health inequalities strategy will contribute to tackling TB in London including the work to address rough sleeping.

For data on HIV please see my response to Mayor's Question 2019/21030.

For Hepatitis C, at the end of 2018 the estimated number of people with chronic hepatitis C infection in London was 14,200 (95 per cent credible interval 11,900-16,900)[1]. We know that many of them remain undiagnosed.

While London accounted for 36 per cent of all people with TB in 2018 - over double the national rate - cases continue to decline. In 2018 1,691 people notified with TB. This was a drop of more than half from the peak in 2011[2].
