The management of healthcare-associated infections(HAIs)outbreak is a critical component of hospi-tal infection prevention and control,playing a vital role in safeguarding the patients and healthcare workers.The"Standards for Control of Healthcare-Associated Infection Outbreaks(2025 edition)"that was issued by the Na-tional Health Commission was interpreted from the perspectives of scientific validity,applicability and operability.It covers the aspects such as the background of the revision,main contents(including management re-quirements,epidemiological survey,control effect evaluation.It is stressed on the role of information management systems in enhancing the capability for early detection and early warning of HAIs outbreaks.New additions include emergency response procedures for exposures to unconventional pathogens in healthcare settings,outlining specific response measures and key action points.The standard clarifies that infections evolve dynamically and must be cat-egorized based on whether the outbreak pathogen has a defined incubation period.It defines the longest incubation period for assessing effective outbreak control and establishes criteria for identifying new cases.This standard ap-plies to medical institutions of all levels and types and can also be referenced for the control of infection outbreak in temporary special settings during the prevalence of infectious diseases.

Objective To analyze adherence to short message service (SMS) based obesity intervention in overweight and obesity adults in Beijing.Methods Sixty-three participants received a 24-week (3 stages) SMS obesity intervention,and were then required to answer questions about their performance of 3 individualized weight loss goals daily via SMS.Three group sessions and monthly coaching call were also conducted.Adherence was graded according to the SMS reply rate and goal score.Logistic regression analysis was computed to analyze the influence factors of adherence.Results Among 55 intervention completes,the rate of loss to follow-up was 12.7％.Adherences of 55 participants were ranked as 3 levels:high level (SMS reply rate 5-7 d/wk and score ＞ 9) 56.4％,middle level 36.3％ and low level 7.3％.Association between body mass index (BMI) change and adherence was statistically significant (r =-0.241,P =0.026),similar to relationship between waist circumference (WC) change and adherence (r =-0.303,P =0.005).At 24-week,BMI and WC of the high level group were reduced by 2.26％ and 3.80％,respectively,and the changes were statistically different among 3 groups (BMI:F =3.659,P =0.033 ; WC:F =4.699,P =0.013).Logistic regression analysis showed that advanced age (odds ratio (OR) =1.108,95％ CI:0.997-1.231),obesity (OR =12.974,95％ CI:1.245-135.195),more suitable goals(OR =1.451,95％ CI:0.974-2.162),weight lost early (OR =10.982,95％ CI:1.608-75.007),usually replied SMS in the morning (OR =6.725,95％ CI:1.098-41.201)were favorable factors of adherence.High expectation to weight loss (OR =0.055,95％ CI:0.005-0.626)was the negative factor of adherence.Conclusions SMS is a promising tool to promote self-monitoring adherence for Chinese overweight and obesity adults,and good adherence indicates more weight loss.Many factors could influence SMS adherence,and more strong evidence on adherence to SMS-based obesity intervention are desired.
