The Cold Viruses
The rhinoviruses and the coronaviruses are the most common causes of a cold. According to the National Institute of Allergy and Infectious Diseases (NIAID), the rhinoviruses cause about one-third of all colds (30 to 35 percent), while the most common causes of alt colds are the coronaviruses. However, the cause of 30 to 50 percent of alt colds remains unidentified.
根据这里面的语境,alt cold 就是*感冒的意思(有别于儿童感冒)。相关知识可以查阅有关感冒的医学类书籍。*感冒与大部分儿童感冒有很大区别。感冒一词美国人很重视,因为他们感冒的致死率很高。。
