1968-69：“香港型流感”H3N2大流行1968-69: "Hong Kong flu" H3N2 Pandemic

　　该病毒首先在香港被检测出来，在1968-69年流行期间大约导致三万四千美国人死亡。H3N2病毒如今仍在循环流行。那些年龄在65岁以上的病人最有可能死亡。这种病毒很像1957-58年的“亚洲型流感”病毒，因此许多人已经有了一定的免疫力。First detected in Hong Kong, this virus caused roughly 34,000 deaths in the United States during the 1968-69 season. H3N2 viruses still circulate today. Those over the age of 65 were most likely to die. The virus was similar to the 1957-58 Asian flu, so some people may have had some level of immunity.
