Flu season typically peaks between December and February in the northern hemisphere. It caused an estimated 61,000 deaths and 810,000 hospitalizations in 2019 in the US, according to the US Centers for Disease Control and Prevention (CDC).
北半球的流感季通常在当年12月至次年2月达到高峰。根据美国疾病控制和预防中心的数据,2019年,流感在美国造成约6.1万人死亡、81万人住院。
By comparison, Covid-19 has killed more than 166,000 people in the US with months to go before the end of the year, according to the Johns Hopkins University Coronavirus Resource Center. The disease hospitalized an estimated 293,000 people just between March and May 2020, according to the healthcare consulting firm Avalere. Those deaths and infections also occurred despite huge efforts – such as shutting down large parts of the US economy – being put into action to slow the virus’s path.
相比之下,根据约翰斯·霍普金斯大学冠状病毒资源中心的数据,虽然目前距离年底还有数月,但新冠肺炎已经导致美国逾16.6万人死亡。据医疗咨询公司Avalere的数据,仅在今年3月至5月间,就有约29.3万人因新冠肺炎住院。尽管采取了巨大的努力,比如停止大部分经济活动,以减缓病毒传播的速度,但仍未能阻止患者死亡和感染。
While the flu’s seasonality is not clearly understood, the way it spreads is well documented. Flu is transmitted in much the same way Covid-19 spreads: coughs, sputters and sneezes in close proximity in closed spaces and in crowds. For those reasons, social distancing measures are effective against influenza as well as Covid-19.
