RESUMEN
In December 2019, novel coronavirus pneumonia epidemic occurred in Wuhan, Hubei Province, and spread rapidly across the country. In the early stages of the epidemic, China adopted the containment strategy and implemented a series of core measures around this strategic point, including social mobilization, strengthening case isolation and close contacts tracking management, blocking epidemic areas and traffic control to reduce personnel movements and increase social distance, environmental measures and personal protection, with a view to controlling the epidemic as soon as possible in limited areas such as Wuhan. This article summarizes the background, key points and core measures in the country and provinces. It sent prospects for future prevention and control strategies.

RESUMEN
Objective@#To analyze the deaths with antiretroviral treatment among adult HIV/AIDS patients in Liangshan Yi Autonomous Prefecture from 2005 to 2015, in order to understand the epidemiological characteristics and to further reduce the mortality rate in Liangshan Prefecture.@*Methods@#The relevant information was collected through the Management Database of Antiretroviral Treatment from the National AIDS Comprehensive Prevention Information System.@*Results@#From 2005 to 2015, a total of 14 219 adult HIV/AIDS patients received antiretroviral treatment and 1 425 death cases were reported during the treatment. The cause of death was mainly AIDS-related diseases (58.9%), and the cumulative mortality rate was 10.02%. Gender, age, the way of infection, duration of antiretroviral therapy, clinical stage when received antiretroviral therapy, and CD4+ T lymphocyte levels were factors for the mortality rate (P<0.001). The mortality increased with older age, higher initiation clinical stage and lower level of CD4+ T lymphocyte. Among the death cases, 82.6% were male, 1 182 (82.9%) were married or cohabited, most aged between 30-39 years old (48.6%). At the initial point of receiving antiretroviral therapy, 49.7% of the cases with CD4+T lymphocytes levels< 200/μl, 61.2% of the deaths cases were>1 000 copies/ml during the last viral load test, and 16.2% of deaths were ≥500/μl in the last CD4+T lymphocyte test; 44.5% of deaths were received antiretroviral treatment within one year.@*Conclusion@#Early and timely antiretroviral therapy should be carried out. It is necessary to strengthen the propaganda of antiretroviral therapy and to improve the management quality of follow-up information of antiretroviral therapy case files, and to improve the medication compliance of patients.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the survival time and affecting factors among AIDS patients under antiretroviral treatment, between 2008 and 2013 in Liangshan, Sichuan province.</p><p><b>METHODS</b>Observational retrospective cohort study method was applied. AIDS patients were chosen from China's national comprehensive prevention and control management system of AIDS in Liangshan, during 2008-2013. Related information on demographics, source of infection, pathogenesis, treatment and death was collected. Cox proportional hazards model was applied to analyze the factors that might affect the survival on patients.</p><p><b>RESULTS</b>Among the 8 321 cases, ranging from 18 to 87.5 years old (mean age as 34.2 ± 9.8), 3 021 died and 3 721 patients had received HAART treatment. The total mortality rate dropped from 43.9/100 person-years to 20.7/100 person-years from 2008 to 2013. In the treatment group, mortality rate dropped from 27.3/100 person-years to 5.1/100 person-years, while in the untreated group it remained high-between 45.0/100-50.8/100 person-years. Proportion for the treatment coverage increased gradually, from 5.8% in 2008 to 54.5% in 2013. Median survival time of all the AIDS patients was 35.1 months, but 18.4 months in the untreated group. Survival of all the AIDS patients was associated with factors as: treatment, age when AIDS diagnosis was made and route of HIV infection (P < 0.05). The risk of death among untreated patients was 5.78 times to the treated ones, but did not seem to relate to gender or nationality (P > 0.05). Survival of the treated group was associated with factors as gender, age when AIDS diagnosis was made, nationality, route of HIV infection, CD4(+) T cell count when AIDS diagnosis was made, CD4(+) T cell count at treatment baseline, anemia at the treatment baseline (P < 0.05). Survival of the untreated group was mainly associated with age when AIDS was diagnosed (P < 0.05) while other factors did not seem to be significantly related (P > 0.05).</p><p><b>CONCLUSION</b>Antiretroviral therapy appeared an important factor that affecting the survival of AIDS patients, timely treatment and CD4(+) T cell count provided at the baseline for treatment, were two key factors that affecting the outcome of treatment. Our findings pointed out that tactic factors as: strengthening the detection, monitoring on CD4(+) T cell count, early diagnose and treatment, expanding the coverage of antiretroviral therapy, and appropriate timing for treatment etc., were important ways to enhance the effects of treatment, so as to reduce the mortality rate and prolong the time of survival.</p>
