It's from the CDC, so even though its "factual' it's more truthy that fact. Nonetheless, coronavirus is nothing new. It's the cause of 30% of common colds.

Human Coronavirus Types

Coronaviruses are named for the crown-like spikes on their surface. There are four main sub-groupings of coronaviruses, known as alpha, beta, gamma, and delta.

Human coronaviruses were first identified in the mid-1960s. The seven coronaviruses that can infect people are:

Common human coronaviruses

229E (alpha coronavirus)

NL63 (alpha coronavirus)

OC43 (beta coronavirus)

HKU1 (beta coronavirus)

Other human coronaviruses

MERS-CoV (the beta coronavirus that causes Middle East Respiratory Syndrome, or MERS)

SARS-CoV (the beta coronavirus that causes severe acute respiratory syndrome, or SARS)

SARS-CoV-2 (the novel coronavirus that causes coronavirus disease 2019, or COVID-19)

People around the world commonly get infected with human coronaviruses 229E, NL63, OC43, and HKU1.

Sometimes coronaviruses that infect animals can evolve and make people sick and become a new human coronavirus. Three recent examples of this are 2019-nCoV, SARS-CoV, and MERS-CoV.

Hmm, apparently is is something new. When did the bio-weapons programs begin in earnest?

'''All coronaviruses can trace their genetic ancestry to a common ancestor in the 1950s. SARS-COV-1 and MERS are both beta coronaviruses. SARS-COV-2 likely is a beta strain as well.

Four HCoV-OC43 genotypes (A to D), have been identified with genotype D most likely arising from genetic recombination. The complete genome sequencing of two genotype C and D strains and bootscan analysis shows recombination events between genotypes B and C in the generation of genotype D. Of 29 strains identified, none belong to the more ancient genotype A. Molecular clock analysis using spike and nucleocapsid genes dates the most recent common ancestor of all genotypes to the 1950s. Genotype B and C date to the 1980s. Genotype B to the 1990s, and genotype C to the late 1990s to early 2000s. The recombinant genotype D strains were detected as early as 2004.[5]

Comparison of HCoV-OC43 with the most closely related strain of Betacoronavirus 1 species, bovine coronavirus, indicated that they had a most recent common ancestor in the late 19th century, with several methods yielding most probable dates around 1890, leading authors to speculate that an introduction of the former strain to the human population might have caused the 1889–1890 flu pandemic.[8] HCoV-OC43 likely originated in rodents.[9]

HCoV-OC43 is one of seven known coronaviruses known to infect humans.
