Abstract :
The renowned coronavirus spread throughout
the entire world within a short duration of time and in the
process it destroyed everything it encountered in its path,
like an invisible fire. This article is to review some of the
key features of the coronavirus pandemic and also the
virus that causes it. That is, to review the covid-19 virus,
which is also known as SARS-CoV-2 (Severe Acute
Respiratory Syndrome – Corona Virus – 2). Several
vaccines have been developed worldwide for the
prevention and treatment of this virus, but due to the
limitation of their distribution and manufacturing
capacities, the targeted global “herd immunity” has not
been achieved. Meanwhile, SARS-CoV-2 is constantly
mutating and that unfortunately limits the effectiveness of
various vaccination campaigns, notwithstanding the
speed of the campaigns. Meanwhile, the current antiviral
drugs being used including ivermectin,
hydroxychloroquine, ritonavir and lopinavir have not
resulted into any conclusive benefits to those infected.
Therefore, more effective treatments that are affordable,
safe and available globally are urgently needed for
targeting the SARS-CoV-2 infections. Covid-19 infections
affects the upper respiratory tract and also the lower
respiratory tract. However, about 80% of the patients
with the disease will not require any hospitalization
because their symptoms are relatively mild. But, for the
remaining 20% patients, the disease deteriorates to the
lower respiratory tract and results into pneumonia.
Unfortunately, about 6% of the covid-19 patients with
pneumonia (out of the 20% patients with lower
respiratory tract involvement) eventually develop
respiratory failure which usually require urgent
admission to an Intensive Care Unit (ICU) for adequate
support. The most frequent and commonly reported
symptoms of covid-19 infections are cough, shortness of
breath, and fever. The clinical diagnosis for covid-19
infections can be made using the symptoms, chest
imaging, and exposures history. In addition to that, an
individual that is suspected to have covid-19 can be
evaluated and thereafter confirmed for SARS-CoV-2
based on quantitative Real Time – Polymerase Chain
Reaction (qRT-PCR), which is a viral nucleic acid test. So
far, covid-19 has proven to be a serious global health
threat and it has strained the global healthcare capacity.
Therefore, it is very important and necessary to really
study it and develop more effective pharmacological
treatments which are effective for the treatment and
prevention of the disease. In this article, we will review an
anti-viral therapy made up of quercetin, zinc and
ascorbic acid (vitamin C) combination. This combination
has proven to be quite effective and safe. Also, various
clinical studies and anecdotal evidence supports its
efficacy in the management and prevention of covid-19
infections. The evidence includes a study done at Liaquat
University of Medical and Health Sciences (LUMHS),
Jamshoro, Pakistan and another study at the Department
of Critical Care Medicine, Zhongnan Hospital of Wuhan
University, China.
