COVID-19: A Global Pandemic of 21st Century

Abstract

In last of 2019, the Centers for Disease Control and Prevention started monitoring the outbreak of a new corona virus, SARS-CoV-2, which causes the respiratory illness now known as COVID-19. Authorities first identified the virus in Wuhan, China. More than 82542 case of Corona virus in China at 31 March 2020. Health authorities have identified many other people with COVID-19 around the world. On 31 March 2020, the virus spread more than 750890 People in the World. The World Health Organization (WHO) has declared a public health emergency relating to COVID-19. Since then, this strain has been diagnosed in several residents of world. The CDC have advised that it is likely to spread to more people. COVID-19 has affected at least 213 countries or territories or areas. The first people with COVID-19 had links to an animal and seafood market. This fact suggested that animals initially transmitted the virus to humans. However, people with a more recent diagnosis had no connections with or exposure to the market, confirming that humans can pass the virus to each other. Corona viruses will infect most people at some time during their lifetime. Corona viruses can mutate effectively, which makes them so contagious. Information on the virus is scarce at present. In the past, respiratory conditions that develop from corona viruses, such as SARS and MERS, have spread through close contacts. On 17 February 2020, the Director-General of the WHO presented at a media briefing the following updates on how often the symptoms of COVID-19.However, while some viruses are highly contagious, it is less clear how rapidly corona viruses will spread. Symptoms vary from person-to-person with COVID-19. It may produce few or no symptoms. However, it can also lead to severe illness and may be fatal. On 11 March 2020, WHO declared Novel Corona virus Disease (COVID-19) outbreak as a Pandemic.

Prevalence of Covid-19 Associated Symptoms, Their Onset and Duration, and Variations Among Different Groups of Patients in Bangladesh

“…Among them, α-coronavirus HCoV-229E and HCoV-NL63 bear low pathogenicity, and β-CoVs HCoV-HKU1 and HCoV-OC43 cause moderate respiratory symptoms, identical to a common cold. On the other hand, the other known β-CoVs, SARS-CoV and MERS-CoV could result in a severe and potentially fatal respiratory illness (14,15). The disease is generally known to be transmitted between animals and humans through sneezing, coughing, touching or shaking hands, and contacting a surface or object and the incubation period ranges from 2 to 14 days (9,14).…”

The disease is generally known to be transmitted between animals and humans through sneezing, coughing, touching or shaking hands, and contacting a surface or object and the incubation period ranges from 2 to 14 days (9,14). The infection has been predicted by a loss of smell and taste in addition to other symptoms (16,17).…”

Aplication of ARIMA Model for Forecasting Additional Positive Cases of Covid-19 in Jember Regency

“…In Figure 4.6, the plot of the data forecasting results using the ARIMA model (1,2,3) is shown below. (1,2,3). It can be seen that the data forecast results move closer to the actual data, although they are not exactly the same.…”

“…However, after analyzing and estimating using several models, we obtained the following results: In Figure .5 above, we can see that from the correlogram of residuals, the ACF and PACF plots no longer indicated any lag. Thus, it can be said that there is no autocorrelation in the residuals of the ARIMA model (1,2,3). Therefore, it can be said that the ARIMA model (1,2,3) is a good model Based on this model, we will conduct data forecasting.…”

“…A small percentage of clinically depressed patients may even die [10]. According to [1] by March 31, 2020, the virus had infected more than 750.890 people worldwide. Thus, the World Health Organization (WHO) has declared a public health emergency relating to Covid-19.…”
