美媒：美国为何抗疫失败？无能、阶级暴力、欺骗和谎言(6)

Based on global data, Case Fatality Rates (CFR) averaged one percent for Lassa hemorrhagic fever, mumps encephalitis, all less than Covid.12 “Coexistence with mumps” or “coexistence with smallpox” is unimaginable in developed industrial countries, where children with mumps-induced encephalitis are quarantined and smallpox has been eradicated since 1977. Yet the U.S. media and politicians are urging people to coexist with the coronavirus, which has a much higher death rate.
There is a conscious or unconscious belief that infectious diseases will become progressively less lethal as they mutate, eventually becoming a mild and common disease. Although infectious diseases usually evolve in a mild direction in the long term, it may not necessarily be the case in the short term.13 Immunologists tell us that the evolutionary trajectory of the virus depends on the complex interplay of several factors that shape the response of our immune system to the evolution of the virus. In a scenario where the virus has multiple hosts, such predictions become even more difficult.14
