#Betacoronavirus #Infection #Outbreak, São Paulo, #Brazil Fall 2023, Emerg Infect Dis. https://wwwnc.cdc.gov/eid/article/30/3/23-0990_article

-- We report a #human CoV #OC43 infection #outbreak in hospitalized patients and #HCWs in São Paulo, Brazil, occurring after SARS-CoV-2 cases disappeared. Infection was associated with HCWs in 5 (29.4%) patients. Routine surveillance including a respiratory virus panel can improve coronavirus detection in both healthcare professionals and patients.

Talk of #OC43 causing 1890 "Russian flu" pandemic then milding out.

This is a wild guess.

Original 2005 article:
- Authors state 1890 pandemic was flu
- Antibodies found in certain generations support was flu
- They then state "[h]owever, it is tempting to speculate about an alternative hypothesis, that the 1889-1890 pandemic may have been [a bovine corona jumping to humans']"

This article used to suggest viruses "mild" with time, which is simply not true

Clinical evidence “Russian flu” pandemic of 1889-1891 might have been a coronavirus pandemic

Contemporary medical reports from Britain and Germany on patients suffering from a pandemic infection between 1889 and 1891, which was historically referred to as the Russian flu, share a number of characteristics with COVID-19.

Fifteen years ago, the discussion of the agent responsible took a new turn with an unexpected observation from virologists working at KU Leuven in Belgium. They sequenced the human coronavirus OC43 (HCoV-OC43), and showed that it shared very high nucleotide sequence identity with bovine coronavirus (BCoV).

Notably, with an estimated 4.3 × 10-4 substitutions per site per year, the time to the most recent common ancestor of HCoV-OC43 and BCoV was dated by three methods to 1891, 1873 and 1890.
