In early 2019 the news of COVID-19 began to travel, gradually spreading its tentacles like the sun casting its garment upon the earth to reduce its hotness. Soon, it was no longer a one-country hard kernel to crack. The virus began to move from one country to another through human beings who became the agents for transmitting the virus through contact, which led to contact tracing to track down victims to prevent further spread.
COVID-19 is a highly infectious and dangerous disease that was declared a Public Health Emergency by the World Health Organization (WHO).
People living in highly populated areas with a high population density are more likely to come in close contact with others. Consequently, any infectious disease is expected to spread speedily in highly populated areas.
A recent analysis on COVID-19 cases in the United States Of America (USA) by researchers at Johns Hopkins, Bloomberg School of Public Health, London School of Economics, and Institute of Labour Economics(IZA) concluded that the spread of Covid-19 is not linked with overcrowdedness. They investigated the influence of population density on the COVID-19 spread and related mortality in the context of India. After a careful correlation and regression analysis of infection and mortality rates due to COVID-19 at the district level, they found a moderate association between COVID-19 spread and population density.
THE EMERGENCE OF COVID-19
The gradual beginning and ceaseless spreading of the highly infectious disease COVID-19 has made the World difficult.
The disease has a severe impact on the world economy and many other components of human lives, such as education, employment, and physical, social, and mental condition.
Several researchers suggest that COVID-19 infection is associated with meteorological factors such as temperature, humidity, wind speed, etc.
TRAVEL AND TOURISM
Another Avenue and the critical factor contributing to the COVID-19 Pandemic’s emergence in the United States and internationally is travel and tourism. (Neiderud, 2015).
Epidemic spread through major travel destinations in both compact and sprawling cities. (Alirol et al., 2011).
Severe acute respiratory syndrome (SARS), for instance, emergence as a pendant in 2003, originated from wildlife markets in Guangdong (China) and spread rapidly through the World with international travel (WHO)2007.
Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is another virus outbreak in 2014 in west Africa.
Guinea and Sierra Leone were the centers of the regional epidemic due to the high connectivity and substantial cross-border traffic, even though 64% and 60% of their populations were living in low-density rural areas (WHO) 2014.
In the spring of 2009, a novel influenza A (H1N1) virus emerged. It was detected first in the United States and spread quickly across the United States and the World.
According to Kao et al. (2012), the HINI pandemic of 2009 persisted for a relatively long period in areas in Taiwan with high population density. In the same way, Garreth (2020) finds a position and significant relationship between the death rate from the 1918 influenza pandemic and the State-level population density in the United States.
On the other hand, Chowell et al. 2008 and Nishiura and Chowell, for the same reason, dense areas could also facilitate the transmission of highly contagious diseases. If people are close enough to each other to exchange ideas, they can exchange high contagious diseases, too, at least in theory (Claeser, 2011)
INFECTION RATES NOT LINKED WITH POPULATION
Public Health claims that the infection rates are not linked with population density. In contrast, the death rate is inversely related to population density. (Hamid et al. 2020) except for metropolitan areas where higher infection and higher mortality rates have been noted.
The timing of the outbreak depends on population density, with the denser regions leading an early outbreak, but both COVID-19 infection and death rates are unrelated to urban populations density (Carozzi et al. 2020).
The current world statistic of coronavirus case update for August 2nd, 2021, is as follows:
Total coronavirus case 199, 406, 026
Total death 4, 245, 971
Total recovered 179, 912, 732.
Total persons in mild condition 15, 155, 890 which is (99.4%)
Cases that had an outcome 184, 158, 703
Recovered/Discharged 179, 912, 732, which is (98%)
Death 4, 245, 971.
In conclusion, the Coronavirus disease (COVID-19) Pandemic is recognized as the most severe public health threat since the 1918 influenza pandemic. The Pandemic is responsible for a dramatic change in the way the whole World lives and works now. The offices and other workplaces are undergoing the most enormous scale remote work experiment in the history of man kind, with most people working from home now.
However, most people are still thinking of where to live, which describes an exodus of people relocating since the COVID-19 Pandemic.
