Abstract
Background – The SARS-CoV-2/ Covid -19pandemic is still going on and globally healthcare system is
overstressed with this new burden added with previous NCD & CD in
existence. The First human case of this global pandemic was reported
from Wuhan city of China in December 2019.11https://apps.who.int/iris/bitstream/handle/10665/332197/WHO-2019-nCoV-FAQ-Virus_origin-2020.1-eng.pdfObjective – The main objective of this study is to
illustrate the key features of Covid -19 virus responsible for
continuation and recurrence of this pandemic as well as current latest
status in brief. Setting and design – Different aspects
of Covid -19 structural variations and its effect will be analysed.
Brief details about epidemiological triad will be outlined.Methodology – The explanation will be given to title
through analysis of several accredited findings. The cause of
perpetuation of Covid -19 can be understood by the way of infections and
other related factors. Result- Several factors are
responsible for the continuation of the pandemic.
Conclusion – In the epidemiological triad we have
agent/host/environment…..
Background - The SARS-CoV-2/ Covid -19 pandemic is
still going on and globally healthcare system is overstressed with this
new burden added with previous NCD & CD in existence. The First human
case of this global pandemic was reported from Wuhan city of China in
December 2019. The SARS-CoV-2/ Covid -19 coronavirus belongs to a large
family of coronavirus. Usually they cause respiratory infection in
humans like other respiratory viruses such as rhinoviruses/ human
respiratory syncytial virus/ parainfluenza viruses/
adenoviruses/influenza A & B viruses / enteroviruses / herpes simplex
viruses/ human metapneumoviruses etc.
Globally new covid-19 cases are rising again or we can say alternatively
that incidence rate is increasing. In the last week of March 2021 the
new cases reported globally are more than 3.8 million. At the same time
the number of deaths also increased consecutively for the second
consecutive week. The deaths increased by 5 % compared to previous
week. The total number of death for above mentioned period was over
64000 new deaths. The more alarming fact is that all regions have
reported an increase in incidence rate in last week of March 2021. If we
talk about deaths then except African region all regions reported an
increase in the number of deaths due to covid-19. Added to above facts
still the European region with region of Americas are on the top
accounting for 80 % of all cumulative cases and deaths.22https://www.who.int/publications/m/item/weekly-epidemiological-update-on-covid-19---31-march-2021
There is sharp rise in south East Asia region or actually it’s the
largest increase on global basis that is 21 % increase in deaths with
continued increasing trends in the 3rd consecutive
week. The south East Asian region is also having a huge population as
well as many nations are in developing stage with stressed and
overburdened health system.
Objective - The main objective of this study is to
illustrate the key features of Covid -19 virus responsible for
continuation and recurrence of this pandemic as well as current latest
status in brief. The latest scenario of covid-19 pandemic is as follow:
