Background: Hepatitis C virus (HCV) is a leading cause of chronic liver disease. As yet there is no approved vaccine protects against contracting hepatitis C. HCV seriously affects many people's health in the world.
Methods: In this article, an epidemiological model is proposed and discussed to understand the transmission and prevalence of hepatitis C in mainland China. This research concentrates on hepatitis C data from Chinese Center for Disease Control and Prevention (China's CDC). The optimal parameters of the model are obtained by calculating the minimum chi-square value. Sensitivity analyses of the basic reproduction number and the endemic equilibrium are conducted to evaluate the effectiveness of control measures.
Results: Vertical infection is not the most important factor that causes hepatitis C epidemic, but contact transmission is. The proportion of acute patients who are transformed into chronic patients is about 82.62%. The possibility of the hospitalized patients who are restored to health is about 76.24%. There are about 92.32% of acute infected are not treated. The reproduction number of hepatitis C in mainland China is estimated as approximately 1.6592.
Conclusion: We find that small changes of transmission infection rate of acutely infected population, transmission infection rate of exposed population, transition rate for the acutely infected, and rate of progression to acute stage from the exposed can achieve the purpose of controlling HCV through sensitivity analysis. Finally, based on the results of sensitivity analysis, we find out several preventions and control strategies to control the Hepatitis C.

Background: Public Health and Social Measures (PHSM) are among the commonly used methods to prevent the spread of Corona Virus Disease of 2029 (COVID-19). Vaccination has also been an integral component of infectious disease prevention and control and it has been used widely to protect humans against some of the very serious diseases such as COVID-19. People living with HIV (PLHIV) are known to be more vulnerable to the severest form of COVID-19 than the general population.

Background/objectives: Fishing communities (FCs) around Lake Victoria have been identified as suitable for future HIV vaccine efficacy trials due to their high HIV incidence rates. To inform trial design and implementation, we evaluated adherence to vaccination schedules and study retention in a simulated HIV vaccine efficacy trial (SiVET) among adults from two fishing communities in Uganda.
Methods: A 12-month prospective cohort study enrolled 250 HIV seronegative adults, aged 18-49 years, from one island and one mainland FC.

Introduction: This study aimed to evaluate the epidemiological trends and spatial-temporal distribution of hepatitis C virus (HCV) in mainland China.
Methods: HCV monthly incidence surveillance data from 2004 to 2018 was mainly available from the Public Health Sciences Data Center of China. Five models (Bayesian age-period-cohort, BAPC; Auto-regressive integrated moving average, Auto_arima; Exponential smoothing, ETS; Prophet; Earth) were used to forecast the incidence.

The pentavalent is a vaccine against Diphtheria, Pertussis, Tetanus, Hepatitis B, and Haemophilus type B influenza. A child is considered a pentavalent vaccination dropout if they have received the first dosage as advised but have not obtained the third dose. In Tanzania, the first-dose receiver of pentavalent was approximately 97 %, whereas only 89 % received a third dose.

Background: China, especially the Chinese mainland, is a highly endemic area of hepatitis E, and its incidence rate has been increasing in recent years. Hepatitis E virus (HEV) is the causative agent of hepatitis E, with a variety of domestic animals as potential hosts. The shift in the main epidemic strain and the increasing trend of zoonotic HEV infection in the Chinese mainland need urgent attention.
