That "explosive" nature, however, could potentially be caused - as @arambaut.bsky.social lays out - by a combination of long(ish) term cryptic transmission, linked to sexual networks / sex work, followed by more recent detection and reporting. Again, his thread: bsky.app/profile/aram...

For recent outbreaks of Clade Ib in the DRC, similar patters have been seen, although not the same "explosive" nature we're observing in Sierra Leone. @marionkoopmans.bsky.social's paper: www.nature.com/articles/s41...

Epidemiological and genomic evolution of the ongoing outbreak of clade Ib mpox virus in the eastern Democratic Republic of the Congo - Nature Medicine
Genomic and epidemiologic data suggest that the rapid spread of mpox clade I in the Democratic Republic of the Congo has happened mostly through sexual contact within densely populated areas.

The Wuhan CDC has nothing to do with the origin of COVID-19. Virus genetic engineering and culturing was not their trade (samples were sent to Beijing/Shanghai). They did not have collection of bat viruses from Yunnan. I was told that staff at WCDC did not hear about the outbreak until late Dec.

Early impact of RSV vaccination in older adults in England
Population-based analyses of new vaccination programmes provide robust real-world evidence for post-licensure vaccine evaluation. A 2023–24 vaccine effectiveness analysis of immunocompetent adults aged 60 years or older in the USA showed 80% (95% CI 71–85) protection against respiratory syncytial virus (RSV)-associated hospital admissions.1 In England, the UK Joint Committee on Vaccination and Immunisation advised an initial programme for those turning 75 years old, with a catch-up to age 79 years, pending further data on protection of those who are older.
