Abstract

Studies have shown that sexual transmission, both heterosexually and homosexually, is one of the main ways of HBV infection. Based on this fact, we propose a mathematical model to study the sexual transmission of HBV among adults by classifying adults into men and women and considering both same-sex and opposite-sex transmissions of HBV in adults. Firstly, we calculate the basic reproduction number R0 and the disease-free equilibrium point E0. Secondly, by analysing the sensitivity of R0 in terms of model parameters, we find that the infection rate among people who have same-sex partners, the frequency of homosexual contact and the immunity rate of adults play important roles in the transmission of HBV. Moreover, we use our model to fit the reported data in China and forecast the trend of hepatitis B. Our results demonstrate that popularizing the basic knowledge of HBV among residents, advocating healthy and reasonable sexual life style, reducing the number of adult carriers, and increasing the immunization rate of adults are effective measures to prevent and control hepatitis B.

乙型肝炎病毒在中国同性恋和异性恋传播的模型。
研究表明,性传播,无论是异性恋还是同性恋,都是HBV感染的主要途径之一。基于这一事实,我们提出了一个数学模型来研究成人中HBV的性传播,将成人分为男性和女性,并考虑成人中HBV的同性和异性传播。首先计算基本繁殖数R0和无病平衡点E0。其次,通过分析R0对模型参数的敏感性,我们发现同性伴侣的感染率、同性接触的频率和成年人的免疫率在HBV的传播中起重要作用。结果表明,在居民中普及乙肝基本知识,倡导健康合理的性生活方式,减少成人乙肝病毒携带者数量,提高成人乙肝疫苗接种率是预防和控制乙肝病毒的有效措施。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
