@wanderer_jasnah @juli_bg_bs Most people don't get the flu that often (5-10y so a limited of times in a lifetime). It's one of the reasons why considering covid to be "a flu" or "like the flu" has been completely wrong at least so far.
@wanderer_jasnah @juli_bg_bs 大多数人不会经常感染流感（5-10 岁，因此一生中的次数有限）。这就是为什么将新冠病毒视为“流感”或“像流感一样”至少到目前为止是完全错误的原因之一。
