In Praise of the American Redneck: Neither Trump Nor Pence Is Clued-Up
("No Einstein, Alabama Rednecks Are Reacting Quite Appropriately to COVID-19 Quarantines")
To prove this is so, and to prove it is the transmissibility that is of concern, we follow the macaque trajectory for HIV-2:
SIV / Stump-Tailed Macaque
SIV from stump-tailed macaques: molecular characterization of a highly transmissible primate lentivirus. - PubMed - NCBI
'....is unusual in that it has been associated with outbreaks of infection characterized by aggressive spread within within stump-tailed macaque colonies at two separate primate centers in the United States....SIV was introduced into North American macaques by way of cross-species transmission. A strong candidate for the source of transmission has emerged from genetic analysis of SIVs from West African sooty mangabeys....Since the original isolation of SIVmac from rhesus (Macaca mulatta) and cynomolgus (M. fascicularis) macaques at the New England Regional Primate Research Center in 1985, SIV has been recovered at the Washington Regional Primate Research Center....SIVmne was isolated from pig-tailed macaque (M. nemestrina) that died of lymphoma in 1982. Similarly, at the California Regional Primate Research Center, SIVstm was recovered from a stump-tailed macaque (M. arctoides). Interestingly, this macaque had died during an epidemic of lymphoma and opportunistic infections in the 1970s at the California center.
....
More recently, SIVstm has been associated with a similar outbreak in a colony of M. arctoides at the Yerkes Regional Primate Research Center....Thus, the observed genetic variation among the different macaque isolates might merely reflect genetic variation in the imported feral sooty mangabey population. A second possibility is that all SIV infections in the United States originated from a single source and that further transmission occurred in a fashion similar to the recent example at Yerkes. In this case, genetic variation among the macaque isolates might represent the result of 20 or more years of viral replication in different species of macaques in captivity. Finally, it is possible that a combination of the two hypotheses occurred and that multiple transmissions from several sources have taken place over the years. The unusual episodic communicability of this virus suggests that it may differ significantly from those of the other members of this group.'
Furthermore, the doubled incubation time of HIV-2 as compared with HIV-1 may link to the increased incubation time and lack of symptoms in COVID-19 infection.
