In response to the global spread of the novel coronavirus disease, many preventive measures have been implemented around the world. In order to assess the progression of the outbreak and the effect of public health measures under various facts, it could be useful to examine the infection parameters globally. This study set out with the aim of examining the epidemic variables in ten countries with infection disease compared with Turkey.</p><p id="par0075" class="elsevierStylePara elsevierViewall">The COVID-19 outbreak is characterized as a pandemic because of spreading easily from person-to-person.<a class="elsevierStyleCrossRef" href="#bib0240"><span class="elsevierStyleSup">18</span></a> In this case, public health officials rely on indicators of the epidemic growth rate to assess the risk of observing a major outbreak.<a class="elsevierStyleCrossRef" href="#bib0245"><span class="elsevierStyleSup">19</span></a> The growth dynamics in the early period of the epidemic could vary substantially. However, during the first period, especially on January 2020, the cumulative number of COVID-19 cases globally followed a sharp increase, likely as a result of the outbreak management policy of the government. These dynamics should be taken into account when making inferences on the epidemic growth rate. In Turkey, for example, the possible reason why the growth rate of the outbreak in the first several weeks was a higher percentage could be the inadequate effective preventive measures against the coronavirus epidemic. Because as physical distancing measures, including school closures and strict social interventions, were implemented, the growth rate decreased gradually.</p><p id="par0080" class="elsevierStylePara elsevierViewall">Although fluctuations in the growth rate in Turkey continued to the middle of the period, other countries like the US, France, the UK, and Spain showed a dramatic fluctuation during the first 46-day period. Moreover, the number of confirmed cases in these countries was higher than in other countries on April 25, 2020. Based on these trends, it is possible to assume that the specific measures adopted by the governments to reduce and mitigate the spread of the outbreak are inadequate or ineffective. Because some of those strict measures against the outbreak help to decline the number of confirmed cases and the growth rate of confirmed cases during the period.<a class="elsevierStyleCrossRef" href="#bib0250"><span class="elsevierStyleSup">20</span></a></p><p id="par0085" class="elsevierStylePara elsevierViewall">According to the data from <a class="elsevierStyleCrossRef" href="#fig0030">Fig. 6</a>, the overall case-fatality rate for countries, except Turkey, was lower and ranged from 0% (Russia) to 7.71% (Italy) in the first 46-day period compared to on April 25, 2020, ranging from 0.91% (Russia) to 14.10% (France). This may be because of the following factors. (1) The lack of disease awareness and inappropriate prevention and control may lead to a higher epidemic of infections on April 2020. This fact was experienced in the Mainland of China and its regions.<a class="elsevierStyleCrossRef" href="#bib0255"><span class="elsevierStyleSup">21</span></a> (2) A significant number of asymptomatic or mild individuals cannot be identified.<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">22</span></a> (3) Because of the lack of available laboratory testing, patients with the disease cannot be determined, particularly in the first period of the infection.<a class="elsevierStyleCrossRef" href="#bib0265"><span class="elsevierStyleSup">23</span></a> (4) Because of the possible risk factors, including age and comorbidity, affecting the progression of disease in COVID-19 patients, delayed treatment and inadequate medical supplies can lead to higher mortality rates in the early days of the epidemic.<a class="elsevierStyleCrossRef" href="#bib0270"><span class="elsevierStyleSup">24</span></a> According to the report from WHO, although the scale of asymptomatic or subclinical infections is unclear, they seem to be relatively rare.

However, the overall number of recovered cases has significantly begun to exceed the number of deaths worldwide since the beginning of February 2020.<a class="elsevierStyleCrossRef" href="#bib0280"><span class="elsevierStyleSup">26</span></a> This trend emerged with 214 deaths and 243 recovered in Turkey, for the first time, on the 20th day after the first reported case. However, the United States, Spain, and Italy caught this trend at different times during the outbreak, with on 68th day, 36th day, and 28th day, respectively. It is important to stress that Germany has significantly higher the recovery–death ratio compared to other countries, including Turkey. This ratio in Turkey seems to be at a moderate level among these countries. On the other hand, for the UK, this fact appears dramatically low. Overall, it can be partly concluded from this trend that a high level of testing capacity for a broad sample of the population, early public health measures for the outbreak and a strong health care system to care for people with COVID-19 at high risk can be a crucial factor for underlying the results.</p><p id="par0100" class="elsevierStylePara elsevierViewall">Finally, these results need to be interpreted with caution because of some possible reasons. First, the number of confirmed cases of infection is just based on data with laboratory confirmation for many countries, including Turkey. Especially, asymptomatic cases or patients called asymptomatic carrier or transmitter with very mild symptoms might not be identified.<a class="elsevierStyleCrossRef" href="#bib0290"><span class="elsevierStyleSup">28</span></a> While some cases might be fully asymptomatic, not showing any symptoms yet, others can be presymptomatic, people become infectious before feeling sick. Some studies have estimated that people without symptoms (whether truly asymptomatic or presymptomatic) could be responsible for up to half of the spread.<a class="elsevierStyleCrossRefs" href="#bib0270"><span class="elsevierStyleSup">24,28</span></a> This might be the disease so difficult to contain. A study recently reported that more than 40% of secondary cases were infected during the presymptomatic stage.<a class="elsevierStyleCrossRef" href="#bib0295"><span class="elsevierStyleSup">29</span></a> Hence, there are likely to have unreported cases in countries. Second, patients have typical signs and symptoms COVID-19 (fever, dry cough, fatigue, sputum production, shortness of breath, sore throat, headache, nasal congestion, and myalgia or arthralgia),<a class="elsevierStyleCrossRef" href="#bib0275"><span class="elsevierStyleSup">25</span></a> although they have a negative result of COVID-19 nucleic acid testing. Such misdiagnosed cases, therefore, cannot be included in the cumulative case rates, since actual cases pertain to positive nucleic acid test (PCR) result, not the chest computed tomography (CT) imaging and other clinical symptoms of COVID-19. Finally, different surveillance and response systems in countries for monitoring risk factors might also be a potential impact on the number of cases being reported.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0095">Conclusions</span><p id="par0105" class="elsevierStylePara elsevierViewall">The purpose of the present study was to examine the epidemic characteristics of COVID-19 in the countries with the most cases and to compare the epidemiological features with Turkey in the specific time period between January 22 and April 25, 2020. The findings indicate that the epidemic outbreak of COVID-19 was rapidly spread worldwide and the growth rate of confirmed cases in these ten countries rose to nearly 6% during this period. It is likely that the risk of healthcare system capacity and protecting the most vulnerable population groups may be considered high if the number of cases continued to increase in countries. In this regard, since there is no definitive treatment for COVID-19, it is essential to avoid infection or further spreading. In particular, decision-makers should adopt a series of measures to mitigate the impact of the pandemic, using national surveillance systems.</p></span><span id="sec0040" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0100">Ethical issues</span><p id="par0110" class="elsevierStylePara elsevierViewall">Not necessary.</p></span><span id="sec0045" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0105">Conflict of interest</span><p id="par0115" class="elsevierStylePara elsevierViewall">I declare that I have no competing interests in this study.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:12 [ 0 => array:3 [ "identificador" => "xres1519853" "titulo" => "Abstract" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0005" "titulo" => "Introduction" ] 1 => array:2 [ "identificador" => "abst0010" "titulo" => "Methods" ] 2 => array:2 [ "identificador" => "abst0015" "titulo" => "Results" ] 3 => array:2 [ "identificador" => "abst0020" "titulo" => "Conclusions" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1378167" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres1519854" "titulo" => "Resumen" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0025" "titulo" => "Introducción" ] 1 => array:2 [ "identificador" => "abst0030" "titulo" => "Métodos" ] 2 => array:2 [ "identificador" => "abst0035" "titulo" => "Resultados" ] 3 => array:2 [ "identificador" => "abst0040" "titulo" => "Conclusiones" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec1378166" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Material and methods" "secciones" => array:2 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Study design and data collection" ] 1 => array:2 [ "identificador" => "sec0020" "titulo" => "Data analysis" ] ] ] 6 => array:2 [ "identificador" => "sec0025" "titulo" => "Results" ] 7 => array:2 [ "identificador" => "sec0030" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0035" "titulo" => "Conclusions" ] 9 => array:2 [ "identificador" => "sec0040" "titulo" => "Ethical issues" ] 10 => array:2 [ "identificador" => "sec0045" "titulo" => "Conflict of interest" ] 11 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2020-05-17" "fechaAceptado" => "2020-08-28" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1378167" "palabras" => array:4 [ 0 => "COVID-19" 1 => "Coronavirus" 2 => "Epidemiology" 3 => "Turkey" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1378166" "palabras" => array:4 [ 0 => "COVID-19" 1 => "Coronavirus" 2 => "Epidemiología" 3 => "Turquía" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:3 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Introduction</span><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">The outbreak rapidly spread to more than 200 countries and led to millions of confirmed cases as well as thousands of deaths worldwide.
