截至发稿时，新冠肺炎的第二波浪潮似乎正在欧洲如火如荼地进行。两个多月来，每周新增病例一直在稳步上升，但在过去的几周里，传播速度加快了。在美国，病例也一直呈上升趋势。2020年10月14日，中国报告了自8月7日以来新增新冠肺炎病例的最高数量。总的来说，与严重急性呼吸综合征冠状病毒2(SARS-CoV-2)首次爆发时相比，各国都做好了更好的准备。但10月也标志着北半球流感季节的开始。如果这两种病毒同时激增，即使是最有资源的医疗保健系统也很难应对。南半球避免了这种可能发生的情况。他们最近结束的流感季节异常温和。在工作量明显较低的背后，可能隐藏着数以千计的未被发现的患者。也许，随着各国把资源集中在新冠肺炎上，流感检测逐渐消失了。大量的人可能在家里艰难地度过了流感疫情，而统计学家却隐瞒了这一点。世卫组织总干事Tedros Adhanom Ghebreyesus在2020年6月15日对媒体的吹风会上指出，“许多国家的流感监测要么已经暂停，要么正在下降，由于新冠肺炎大流行，流感信息和病毒的共享急剧下降”。他补充说，“与过去3年相比，我们看到全球流感检测样本的数量急剧减少”。尽管如此，很难想象针对SARS-CoV-2的预防措施对传染性较低的流感病毒没有更有效的预防措施。到去年这个时候，澳大利亚已经确认了298 120例流感病例和812例死亡。到目前为止
At the time of publication, it looks like the second wave of COVID-19 is well underway in Europe. The weekly tally of new cases has been steadily rising for more than 2 months, but the past few weeks have seen accelerated transmission. Cases have also been trending upwards in the USA. Oct 14, 2020, saw the nation register the highest number of new cases of COVID-19 since Aug 7. In general, countries are much better prepared than they were when severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first exploded onto the scene. But October also marks the beginning of the flu season in the northern hemisphere. If both viruses surge simultaneously, even the best resourced health-care systems would be hard pressed to cope. The southern hemisphere avoided such an eventuality. Their recently concluded flu season was exceptionally mild. It is possible that behind the apparently low caseload lay thousands of undetected patients. Perhaps influenza testing fell away as countries concentrated their resources on COVID-19. Large numbers of people might have struggled through bouts of influenza at home, hidden from the statisticians. In a briefing to the media on June 15, 2020, WHO directorgeneral Tedros Adhanom Ghebreyesus noted that “influenza surveillance has either been suspended or is declining in many countries, and there has been a sharp decline in sharing of influenza information and viruses because of the COVID-19 pandemic”. He added that “compared with the last 3 years, we’ve seen a dramatic decrease in the number of specimens tested for influenza globally”. Nonetheless, it is hard to imagine that the precautions against SARS-CoV-2 did not prove even more effective against influenza, a less contagious virus. By this time last year, Australia had confirmed 298 120 cases of influenza and 812 deaths. Thus far
