要控制结核病的传染和流行,就要从结核病的预防着手。目前,最有效的预防措施有三项。一、控制传染源排菌的肺结核病人是结核病的主要传染源,一名涂片检查排菌的病人,每毫升痰液中至少有5,000～10,000条结核菌,它能传染10～20个健康人。在受传染的人中,又可有10%的发病,这些发病者中的半数又将成为新的传染源。所以,传染源不控制,结核病的流行就将持续。控制传染源最有效的办法是给予合理的治疗(详见本刊1982年4期“肺结核治愈的关键是什么?”)。一个经治疗的传染源,其传染性迅速消失。这是因为:①一个治疗前每毫升痰中有数百
To control the spread and spread of tuberculosis, we must start from the prevention of tuberculosis. At present, there are three most effective preventive measures. First, the control of sources of bacteria in the tuberculosis TB tuberculosis is the main source of infection, a smear examination row of bacteria in patients with sputum per ml of sputum at least 5,000 to 10,000 TB, which can infect 10 to 20 healthy people . Infected people, but also have 10% of the incidence of these patients in turn will become a new source of more than half. Therefore, the source of infection does not control the tuberculosis epidemic will continue. The most effective way to control the source of infection is to give reasonable treatment (for more details, see What Is the Key to Tuberculosis Eradication? A contagious source of treatment has rapidly disappeared. This is because: ① a sputum in a milliliter before treatment there are hundreds
