International Public Health Responses to COVID-19 Outbreak: A Rapid Review.

BACKGROUND: The outbreak of Coronavirus disease 2019 (COVID-19) has posed a significant threat to many countries. Since the disease does not currently have a particular treatment, there is a compelling need to find substitute means to dominate its expansion. In this rapid review, we aimed to determine some countries' public responses to the COVID-19 epidemic.
METHODS: In this study, academic databases, including MEDLINE, Scopus, and Embase, were investigated. The keywords applied in the search strategy besides the names of each country were: "Public Health," "Public Response", "Health Policy", "COVID-19", "Novel Coronavirus," "2019-nCoV", and "SARS-CoV-2". The countries included China, Italy, Iran, Spain, South Korea, Germany, France, United States, Australia, Canada, Japan, and Singapore.
RESULTS: The total number of retrieved articles in MEDLINE, Scopus, and Embase in April 2020 was 594, and after removing 259 duplicate articles, 335 papers were screened by the experts. After this investigation, 50 articles, in addition to 12 webpages, were extensively reviewed for the results section. Public health strategies and responses can be divided into four main areas, including monitoring, public education, crowd controlling, and care facilities.
CONCLUSION: According to the results of the management decisions of some governments on quarantining, social isolation, screening methods, and flight suspensions due to the severity and anonymity of COVID-19, it is highly assured that these strategies would be the most successful approaches to confront the present pandemic. Governments should put in place timely and strict measures to halt the spread and diminish its unintended deadly consequences. Copyright: © Iranian Journal of Medical Sciences.

What’s Known

Emergency situations like outbreaks have caused various issues globally.

National and international responses to the outbreaks have had a critical role in reducing the infection rates and preventing the diseases from spreading. Social isolation and quarantining were beneficial in the previous epidemics.

What’s New

Some countries were well- prepared for the outbreak of Coronavirus disease 2019 (COVID-19). However, other regions need to be more promptly adapted to the situation.

According to the results, quarantine and social isolation would be successful techniques to confront the COVID-19 pandemic and an immediate response is a key factor to halt the spread.

Introduction

Brief background and objectives

At the end of December 2019, Novel Coronavirus-infected pneumonia cases were recognized in Wuhan City, China. [1 - 3] These cases, with unspecified etiology, presented with symptoms of dyspnea, fever, dry cough, and bilateral lung infiltration on radiographs. The virus was named Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), and the disease was called Coronavirus disease 2019 (COVID-19) by the World Health Organization (WHO). In late January 2020, WHO announced the COVID-19 outbreak as a Public Health Emergency of International Concern in which countries with vulnerable healthcare facilities may be at an excessive hazard. The disease transmission may be disrupted by early diagnosis, social isolation, instantaneous therapy, and other control measures. [1] This infection has imposed remarkable perils on the global health systems and economic sectors of countries. Since the disease does not currently have a particular treatment, there is a compelling need to find substitute means to dominate its expansion. [4]

COVID-19 outbreak has led the public health officials of several countries to enact policies and manage the spread of the disease by employing different strategies, including encouraging people for self-isolating and quarantining. This rapid review aims to summarize these strategies and responses in some countries and, subsequently, discuss how these measures could help in curbing the virus transmission and comparing the effectiveness of their policies looking at the number of total cases in each of the mentioned countries. The extracted results may be helpful for both policymakers and researchers.

Methods

Search Strategy

In this rapid review, academic databases, including MEDLINE, Scopus, and Embase, were investigated. The keywords applied in the search strategy besides the names of each country were: “Public Health,” “Public Response”, “Health Policy”, “COVID-19”, “Novel Coronavirus,” “2019-nCoV”, and “SARS-CoV-2”. The countries included China, Italy, Iran, Spain, South Korea, Germany, France, United States, Australia, Canada, Japan, and Singapore. In addition to this search, the official government websites of some countries, creditable news websites, and LitCovid literature hub [5] were also reviewed to acquire additional data about the recent national responses and control strategies. After removing duplicate articles, the abstracts of the remaining papers were screened by four experts, including an epidemiologist, a medical informatics expert, a statistician, and an infectious disease expert. Those relevant articles meeting the inclusion criteria were consequently selected to include in the study.

Inclusion and Exclusion Criteria

The inclusion criteria were as follows: 1) Articles reported public health responses to COVID-19 outbreak or control measures when experiencing the virus outbreak, 2) Articles written in the English language, and 3) Articles published in 2020. The papers lacking these measures and out of scope ones were excluded from the study.

Results

The total number of retrieved articles in MEDLINE, Scopus, and Embase in April 2020 was 594, and after removing 259 duplicate articles, 335 papers were screened by the experts. After this investigation, 50 articles, in addition to 12 webpages, were extensively reviewed for the results section. In Table 1, public health responses to the COVID-19 outbreak based on each country are categorized. There are various means by which preventing further transmission of the virus can be conducted, including investigating, categorizing, monitoring, and managing contacts by identifying the patients’ travel routes. Many countries enacted policies on travel restrictions, such as flight suspensions [6 - 14] or close monitoring of the incoming travelers on their arrival at the international airports. [13 , 15 - 17] Some other countries have implemented social distancing and quarantine policies to fight this highly contagious disease [18 - 20] as well as encouraging the limitation of social contacts, postponing events, locking down schools, and isolating suspected cases. [14 , 21] Technological approaches such as telemedicine for remote consultation or monitoring have also been utilized in some regions in the period of the outbreak. [20 , 22 - 24]

According to the published articles, public health strategies and responses are divided into four main areas:

1) Monitoring: In this respect, countries investigate the whole or parts of the community by either using tele-monitoring strategies or broad investigation in airports or borders of the region. Approaches, such as the utilization of Global Positioning System/credit card records or the development of websites for self-monitoring or psychological consultation services, were also employed in some countries, specifically in South Korea and Singapore.

2) Public education: To provide community education, many governments attempted to offer transparent information about the virus. Additionally, information on preventive measures or proper practices in the community were delivered to the people through diverse sorts of media or messaging services.

3) Crowd controlling: Governments employed some policies to diminish gatherings. These approaches included social distancing, quarantining, street traffic controlling, school and university closures, postponing events, and shutting down some businesses.

4) Care facilities preparation: Constructing or preparing suitable care settings, including major hospitals with the highest degree of facilities, were other responses in some countries. Hospitals or shelters for caring suspected or confirmed cases at both stages of therapy and recovery were built or allocated. These facilities might subsequently reduce the death rate in these countries.

The mentioned control measures control measures in some countries could bring success strategies in coping with the current outbreak. However, other countries require to enact stricter laws or implement more practical policies. Based on the Worldometers website, [25] some countries could control the virus, and their total cases rate has remained steady after a specific date. Some other countries with a rising rate of total cases curbed their death rate, although their cases are still growing to a higher degree.

Discussion

The world has encountered three outbreaks since 2002 with the epidemic of SARS-CoV, followed by MERS-CoV in 2012, and COVID-19 in 2019, which spread swiftly to several countries and threatened public health. [70] The immediate spread and its high transmission rate between people have caused global distress. [71 , 72]

In South Korea, some methods for information collection were introduced for the screening and management of COVID-19 cases. By employing these techniques, precise information about the location and time of exposure and other details would be accessible to the general public. Since the release of a patient’s contacts violates the patient’s privacy, a protocol to protect this critical issue must be created. [63]  Early and rapid responses to the outbreak as well as implementing preventive strategies, have helped South Korea to preclude community infection and limit it to some specified medical centers. By utilizing appropriate approaches, entrance of COVID-19 patients, and simultaneously, the dissemination of the virus across the country have been deterred. [67] Although South Korea was once one of the most infected countries outside China, the outbreak has reached a period of stability after stringent monitoring approaches and mass quarantine. [17] Based on the “Worldometers” statistics, the total cases in South Korea had been rising sharply until early March 2020, while since then, the rate has been experiencing a gradual increase. [25]

Singapore has used a robust surveillance program to identify many cases and restrain them at a personal level. By early identification of cases by monitoring and intensive contact tracking among confirmed cases along with implementing border control policies, Singapore has managed to prevent the virus from spreading without substantial disturbances to daily routine life. [17] Additionally, Singapore had the experience of the 2003 SARS outbreak and performed well due to its readiness. Intensive Care Units (ICUs) of the country were fully prepared and responded swiftly to the virus outbreak. [17 , 58 , 59]

Although in Australia, the number of confirmed cases is rising, the death rate in this country has remained relatively low. This might be the consequence of the country rapid response to the emerged crisis through control measures such as social distancing, public education, and the use of technological advancements. [20] Similar to Australia, Singapore has experienced a very low death rate, thanks to its early responses and control policies. [25]

Iran is among countries that have launched a psychological assistance system for residents as well as establishing a self-monitoring website for suspected cases of COVID-19. [42] This country has made several attempts to combat the epidemic, but now it seems that it takes more cohesive, prompt, and effective interventions to halt the spread of this virus, specifically among the most susceptible population. [73] Additionally, adequate and stable economic resources and the effective utilization of them are required. [74]

Social distancing and travel restrictions were among the key methods used by Japan government to confront the recent crisis. [12 , 49] This country has successfully controlled the virus outbreak with a comparatively low casualty rate. [25]

According to the epidemic control experts of Canada, the experiences with the SARS outbreak could positively affect Canada’s response to the epidemic of COVID-19, specifically in the field of facility preparation. However, the increased burden in hospitals and care settings due to the growing number of new cases might remain a key challenge. [56]

Given the accelerated proliferation of the disease and the need to offer urgent care treatment to an increasing number of patients, the current COVID-19 outbreak in Italy has imposed a tremendous pressure on the healthcare system. [38] Although the Italian health system was highly equipped, and the government responded rapidly to the outbreak, this country was not prepared enough to deal with the COVID-19 epidemic, and the number of cases is still rising. This situation has led to several challenges for the healthcare system all over this country. It seems that more appropriate measures of team working, proactive planning, and training can provide a better support in coping with this epidemic. [24] In Italy, data on the prevalence of the disease in asymptomatic individuals were deficient. Therefore, the actual prevalence and precise mortality rate were unclear. In this case, more apparent and comprehensive data are also required to help decision-making and increase consciousness among the public. [75]

Although some countries such as Spain and France have implemented of suitable control strategies including massive lockdown to combat the epidemic, [18 , 46] more real-time screening of the transmission and mortality are required to be prioritized in these countries. [76] In Spain, the government’s late response to the outbreak was the leading cause of its failure in controlling the disease. In addition, due to the financial crisis in this country, the hospitals have been experiencing an austere decade. [77] In France, the underlying reasons might be different; the French citizens tended to follow the national lockdown policies less firmly than other nations. [78]

At the beginning of the epidemic, China led the virus transmission rate with the fastest pace of the spread, while in the next few weeks, other countries took over China. [79] As mentioned above, Italy and Spain confronted a remarkable increase in the number of confirmed cases and deaths. As on March 19, 2020, it was reported that Italy overtook China with more than 3400 deaths from the virus [80] and at the time of writing, United States has the highest total cases compared to other countries. [25] In the United States, the comparison between New York and California would be an excellent illustration of a rapid response. California, unlike New York, has successfully managed to curb the virus from spreading. Disease prevention experts believe that the most significant distinction between these two regions is not a matter of population or location, but the time people began staying at home, and distinctions in their social distancing approach. In general, New York has experienced nine times more number of cases, seven times higher number of hospitalized patients, and fourteen times more fatalities than California. [81]

Although China was the first infected country with once the highest rate of confirmed cases and mortality, looking at its present statistics, it can currently be categorized as a successful country in controlling the disease with strengthened strategies and public health response. [25] The community was also well-informed on COVID-19’s significance to conform with the national approaches of mask-wearing, hand-washing, social distancing, and temperature screening. Additionally, by retaining a firm containment policy, China is seeking to restore usual social and economic activities. [30] However, in the early days of the epidemic, there were some failures and negligence, the government avoided identifying the epidemic and undermined its seriousness in the initial days. [82]

Regarding management and investigative strategies, there has still been a remarkable unfamiliarity in many countries. In this case, international cooperation would be beneficial in controlling the pandemic, [83] and by screening the situation deeply, further knowledge about the new virus would be gained, and nations can respond better. [84] The most known measures to control and prevent the disease include finding suspected cases and their contacts, blocking the transmission of the virus by isolation and personal protection as well as managing the infection sources. [85] There are also some prediction models in which experts forecasted the positive impact of these plans on controlling COVID-19 infectious transmission. [86] More efficient clinical management of the infected patients in addition to public health preparedness [1] and a prompt and accurate screening of the epidemic are needed in all countries in order to succeed in managing the spread of the infection. [87]

Conclusion

According to the results from the management decisions of some governments on quarantining, social isolation, and flight suspensions, it is highly assured that these strategies would be the successful techniques to confront the present pandemic due to the severity and anonymity of COVID-19. In addition to those strategies, some countries have focused more on the utilization of robust case detection and screening approaches. All in all, governments should enact serviceable laws and put in place timely and strict measures to halt the disease spread and diminish its unintended deadly consequences.
