A Study Of Prevention And Control Strategies Of COVID-19 And Effect Evaluation

ObjectiveTo explore COVID-19 prevention and control strategies and their effect in four Southeast Asian countries,to analyze relevant factors affecting the effect of epidemic prevention and control,and to summarize successful experience and shortcomings of their strategies,so as to provide reference for global and Chinese response to COVID-19 and other severe public health emergencies.MethodsBased on the geographical location,economic development level and diplomatic relations,four countries in Southeast Asia,namely Singapore,Thailand,Vietnam and the Philippines,were selected as the research objects.Relevant literature,policy documents and data were obtained from literature database,government official websites,news websites and other databases.Comparative analysis was used to compare the health status and the status of COVID-19 epidemic in four Southeast Asian countries.The evolution process of COVID-19 epidemic was analyzed by content analysis,and specific prevention and control policies were described and classified.Use the three indicators:infection rate,cure rate and mortality rate as the standard to make a basic evaluation of the effect of epidemic prevention and control in the four countries.The related factors affecting the prevention and control effect were analyzed by multiple linear regression.Results(1)The health status of the four countries in Southeast Asia: Ranked from excellent to poor health level,were Singapore,Thailand,Vietnam and the Philippines;In terms of prevention and control of infectious diseases,among the four countries,Singapore has made solid work and achieved the best prevention and control effect,while the Philippines has a weak capacity to deal with infectious diseases and the worst prevention and control effect.Vietnam has made some progress in the prevention and control of AIDS and malaria,but the prevention and control capacity of tuberculosis needs to be further improved.Thailand still needs to do more,especially on malaria control;In terms of health resources and health costs,Singapore was significantly better than the other three countries,while the Philippines was the worst of the four countries.(2)Status of the epidemic in four Southeast Asian countries: As of 8 March 2021,the cumulative number of diagnosed cases in Singapore was 60,046,the cumulative number of deaths was 29,and the cumulative number of cured cases was 59,894.Thailand has recorded a total of 26,441 diagnosed cases,85 deaths and 25,777 cured cases.In Vietnam,the cumulative number of diagnosed cases was 2,524,the cumulative number of deaths was 35 and the cumulative number of cured cases was 1,920.In the Philippines,the cumulative number of diagnosed cases was 597,763,the cumulative number of deaths was 12,521 and the cumulative number of cured cases was 545,912.(3)The effect of prevention and control in four Southeast Asian countries: Among the four countries,Singapore has the highest infection rate(1.04%),followed by the Philippines(0.56%),Thailand(0.04%)and Vietnam(0.00%).Among the four countries,the mortality rate of COVID-19 patients in the Philippines was the highest(2.09%).Followed by Vietnam(1.39%),Thailand(0.32%)and Singapore(0.05%).Among the four Southeast Asian countries,Singapore has the highest cure rate(99.76%),followed by Thailand(97.49%),the Philippines(91.33%)and Vietnam(76.07%).(4)Related factors affecting the effectiveness of epidemic prevention and control in four Southeast Asian countries: facial coverings,restrictions on gatherings and school closing are the same factors associated with the cumulative number of diagnosed cases of COVID-19 in the four countries.Testing policy,facial coverings,and restrictions on internal movement are the same factors associated with cumulative COVID-19 deaths in the four countries.Cancel public events,school closing and workplace closing are the same factors for the cumulative number of patients cured of COVID-19 in the four countries.Restrictions on gatherings are the same relevant factor associated with the daily increase in COVID-19 in the four countries.Conclusions(1)Singapore has a high cure rate but an extremely high infection rate of COVID-19;Vietnam has a low infection rate but a high mortality rate;The Philippines has high infection rate,high mortality rate and poor cure rate.In contrast,Thailand has the best comprehensive epidemic prevention effect among the four Southeast Asian countries.(2)The severity of the policies of facial coverings,restrictions on gatherings and school closing is positively correlated with the decline in the cumulative number of diagnosed cases in the four Southeast Asian countries.In addition,the severity of policies restricting aggregation is significantly associated with the number of new diagnoses per day.(3)Lessons learned from the experience COVID-19 prevention and control in four Southeast Asian countries:Singapore: Establishing an efficient tracking system;Release information transparently and openly.Thailand: Unity and coordination of government;Control of entry points;Maintain risk communication with the public;Pay attention to infection prevention and control in communities and health care settings;Extensive mobilization of grass-roots health volunteers;Actively implementing clinical treatment.Vietnam:Taking full advantage of political system;Vigorously integrate social resources;Mobilize the public to cooperate.Philippines: Implementation of community hierarchical segregation system.(4)Inadequate COVID-19 prevention and control policies in four Southeast Asian countries: Weak health systems;Lack of materials and funds;Missing the best time for prevention and control;Ignoring the ability of vulnerable groups to prevent epidemics.(5)In short,COVID-19 seriously endangers people’s health and global safety.In the context of the global pandemic,no country or region can stand alone.Not only Southeast Asia,but the world must carry out multi-dimensional prevention and control to build the Community of Human Destiny.
