The current pandemic is caused by the virus SARS-CoV-2. It is
predicted to have an R0 value between 2 and 2.5. What factors would
cause the R0 value for SARS-CoV-2 to increase or decrease between
different populations of people?
Solutions
Expert Solution
Ans-
factors which decreases R0
value are we stay inihome and should be lockdown, self quarantine ,
social distancing etc if this not fallow by people then R0 value
increases to cov 2 , because virus spread fastly from one person to
another.
The virus (SARS-CoV-2) that causes Coronavirus Disease 2019
(COVID-19) spreads easily enough to have caused a global pandemic
hard to contain so far. Effective containment needs to be informed
by some key epidemiological factors.
One such factor is called the “serial interval” and it
represents the “duration between symptom onsets of successive cases
in a transmission chain.” That is, if person A (infector) transmits
the virus to person B (infectee), then the serial interval is the
amount of time between...
In relation with the SARS-CoV-2 (the new Corona virus) pandemic,
UK government followed “Herd immunity strategy”; based on what you
studied about the concept of herd immunity, define the concept ,
explain how the concept might be applicable in real life and give
your opinion about the strategy. (100 – 150 words)
Various experiments have shown that the SARS CoV-2 is
an RNA virus that enter the human cells through a transmembrane
receptor called angiotensin converting enzyme 2 (ACE2). Polymerase
chain reaction (PCR) and genome sequencing have been cardinal in
both diagnosis and research into the COVID-19 pandemic. Currently,
DNA sequences of both SARS CoV-2 virus and susceptible human hosts
are available. As a student of molecular biology and biotechnology,
use the above information to answer the following
questions.

SARS-CoV-2, the virus that causes CoVid-19, belongs to
the Coronaviridae family. Viruses under this family have a genome
made of single-stranded positive-sense RNA. Is this similar to the
viral genome of HIV? If so, do you think that – in theory – they
would have similar replication cycles?
What is the Spike protein found in the SARS-CoV-2 virus?
Describe the structure of the S protein (quaternary, tertiary,
secondary and primary protein layers). Also highlight key domains
and features of the structure of the S-protein that are important
for its function.
For the new virus SARS-Cov-2, carefully describe the steps
leading to the initiation of a primary adaptive immune response
upon infection and the effector mechanisms produced to clear the
infection in terms of receptors and effector molecules specific to
the type of pathogen.
Case study: SARS-CoV-2
a) Define the terms R0 and case fatality rate,
b) Discuss the factors that influence the case fatality
rate.
c) Discuss how SARS-CoV-2 enters human cells, the antigenic
target of vaccine approaches and the immune response they aim to
induce, and how this would protect against infection.
Virus A has an R0 of 2
Virus B has an R0 of 11
Virus C has an R0 of .5
If you assume it takes ONE DAY for
each of these viruses to infect the new people, then how many
people will be infected by each of these viruses after 17 days?
