@Americanhope78 @DrEricDing Not really. There are many different "cold" viruses, and most of them aren't even coronaviruses. Multiple colds per year is usually due to getting infected by different ones. It is possible to get infected by the same one after six months, but not common.
@美国人希望78@drericing不是真的。有许多不同的“感冒”病毒，其中大多数甚至不是冠状病毒。每年多发性感冒通常是由于感染了不同的感冒。六个月后可能感染同一种病毒，但并不常见。
