Given the reporting delay from symptom onset to case ascertainment, we cannot yet determine if transmission has stopped increasing.ĭetailed case interviews show that traditional contact tracing is currently challenging, but these interviews identify transmission networks, risk factors and behaviours that can be used to tailor public health communications and target intervention delivery. A high proportion of cases are London residents, and the majority are male. Up to 8 June 2022 there were 336 laboratory confirmed cases of monkeypox in the UK. Wider significant community transmission – with potential for endemic and local epi-zoonotic disease. Transmission within multiple sub-populations or larger sub-population.
Transmission within a defined sub-population with high number of close contacts. Incursions from rest of the world – small numbers of imported cases with limited onward transmission. At present, England is judged to be in Level 2 and we are monitoring closely for any evidence of Level 3. These may be refined with better understanding of modes of transmission. The outbreak can be considered to fall into one of 4 potential levels of transmission. Potential levels of the outbreak in England
It includes early evidence and preliminary analyses which may be subject to change. This briefing is produced to share data useful to other public health investigators and academic partners undertaking related work. The UK Health Security Agency ( UKHSA) is working with the NHS and the public health agencies of the 4 nations to investigate the monkeypox outbreak in the past few weeks.
