Background
Recurrence continues to place significant burden on patients and tuberculosis programmes worldwide, and previous studies have rarely provided analysis in negative recurrence cases. We characterized the epidemiological features of recurrent pulmonary tuberculosis (PTB) patients, estimated its probability associated with different bacterio...
What is already known about this topic?:
The association of diabetes mellitus (DM) with both increased risk of tuberculosis (TB) and unfavorable treatment outcomes has been identified by many studies (1). However, epidemic data for TB cases in DM patients is absent in China.
What is added by this report?:
This current population-based prospectiv...
Abstract Background Part of tuberculosis (TB) patients were missed if symptomatic screening was based on the main TB likely symptoms. This study conducted to compare the yield and relative costs of different TB screening algorithms in active case-finding in the whole population in China. Methods The study population was screened based on the TB lik...
BACKGROUND
A subset of patients who complete standard treatment for pulmonary tuberculosis (PTB) develop TB recurrence.
OBJECTIVE
This study characterized the epidemiological features of recurrent PTB patients to estimate recurrence probability associated with different smear test results and examine risk factors associated with recurrence.
METHO...
Background
In 2005, China established an internet-based Tuberculosis Information Management System (TBIMS) to monitor changes in tuberculosis (TB). Many scholars have conducted epidemiological research using TBIMS; however, few studies assessing control strategies have been performed based on this platform data. Henan province is a high TB incidenc...
BACKGROUND
Although the studies of surveillance and epidemiological characteristics of tuberculosis (TB) notified to the Chinese CDC Tuberculosis Information Management System (TBIMS) are much more, few assessment studies of control strategies have been performed.
OBJECTIVE
As a high incidence region of TB, following the nationwide prevention and...
Background: The World Health Organization (WHO) End TB Strategy meant that compared with 2015 baseline, the reduction in pulmonary tuberculosis(PTB) incidence rate should be 20% and 50% in 2020 and 2025, respectively. The incidence number of PTB in China accounted for 9% of the global total in 2018, which ranked the second high in the world. From 2...

Background:
In 2013, a tuberculosis (TB) outbreak occurred in a middle school in Henan province of China. An outbreak survey was carried out in the school.
Objectives:
This study was undertaken to investigate the detection rate of TB cases and those with strong Mantoux positive (SMP), defined as tuberculin skin test (TST) indurations of 15mm or...

... Delay in the diagnosis of TB endured obstacles in Ethiopia, [5] and health facility-driven delays were frequent among smear-negative, first sought health care, and among rural. [5,18,19] A previous study showed that many patients visited several health facilities up to four rounds with a median of two before getting their final TB diagnosis [20] and there have been many challenges that contribute to the low case-finding status of the country. [21,22] However, evidence and recommendations on how to mitigate the delays are limited. ...

... It is very consistent with the epidemic characteristics of tuberculosis in other provinces of China. For example, from 2005 to 2018, 70.45% of the total cases of tuberculosis in Henan Province were male, the median age was 48 years old, and the number of farmers and herdsmen reached 81.5% [30]. Men may be more socially active and smoke more than women, which increases the risk of TB [31,32]. ...

... The principal sources of PTB case detection among students were passive findings and referrals during the study period, whereas only a small proportion of PTB cases were detected by active screening. This demonstrated that increased regular screening and health surveillance among students, particularly those with latent PTB infection that refused preventive treatment, should be considered to avoid PTB onset and possibly subsequent outbreak in this special group (43,44). ...
