一篇文学作品中有一段这样写道:……一位肝炎病人削好一只苹果递给来探望他的朋友,朋友迟疑地接过去拿在手里不吃,还不在病房的凳子上坐下,朋友告别时把苹果扔在了病房拐角处,病人对此情此景表现很能难过。……根据前面描述,病人大可不必难过。因为朋友并非嫌弃病人本身,而是主动隔离肝炎病毒。病毒是无情面的,尤其甲型肝炎,传染源主要是病人。病毒通过污染的手、水、食物、食具等经口感染。一般在发病2——3周后,随着病毒特异性抗体的产生,血液和粪便的传染性才逐渐消失。别说病人削苹果给人吃,就是病人拿过的住院单、饭票、货币都要消毒。病毒是比细菌还小的微生 One passage in a literary work reads: "A Hepatitis patient cuts an apple and hands it up to visit his friend, who hesitates to take it in his hand and not sit down on a ward’s bench When a friend bid farewell to the apple threw the corner of the ward, the patient is very sorry about the performance of this scene. ... According to the previous description, the patient may not have to be sad. Because friends do not disdain the patient itself, but take the initiative to isolate the hepatitis virus. Viruses are merciless, especially Hepatitis A, the source of infection is mainly the patient. The virus is contaminated by hand, water, food, utensils and other oral infections. Generally in the 2 to 3 weeks after onset, with the emergence of virus-specific antibodies, blood and faecal infectivity was gradually disappear. Not to mention patients cut the apple to eat, that is, the patient took the hospital bill, meal tickets, currency should be disinfected. Viruses are microbes smaller than bacteria
