COVID-19: An unwelcome guest that won’t leave

[摘要] The SARS-CoV-2 pandemic, with its multiple surges, is seemingly lasting forever, although it has actually been with us for a little more than a year. Despite recent setbacks, with difficulties in vaccine production and with safety concerns over a rare but potentially fatal (and possibly autoimmune) platelet activation-related coagulopathy with thrombosis and thrombocytopenia syndrome,1 there is a sense that the end of the infection phase is within reach. Of course, tempering that optimism are the ongoing viral mutations that may exhibit increased virulence or vaccine resistance, and significant swaths of the population voicing “hesitancy” to get vaccinated and to wear a mask, which may slow the development of effective herd immunity.
