2. HISTORY
COVID-19 is one of several emerging infectious disease
outbreaks in recent decades with significant public health and
economic impacts.
The last of these were the influenza pandemics in 1957 and
1968, each killing more than a million people around the
world.
COVID-19, declared a pandemic by the World Health
Organization (WHO) on 11th March,2002.
And escalated worldwide, affecting over 2.5 million people in
185 countries, with over 187,000 deaths.
While the world is still witnessing its spread, most countries
are experiencing direct and indirect impacts of the global
pandemic on their economy and society to varying degrees.
4. Introduction
Coronavirus:
Coronaviruses (CoV) are a large family of viruses that cause
illness ranging from the common cold to more severe diseases
such as Middle East Respiratory Syndrome (MERS-CoV) and
Severe Acute Respiratory Syndrome (SARS-CoV).
A novel coronavirus (nCoV) is a new strain that has not been
previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted
between animals and people.
Detailed investigations found that SARS-CoV was transmitted
from civet cats to humans and MERS-CoV from dromedary
camels to humans.
Several known coronaviruses are circulating in animals that
have not yet infected humans.
6. SARS-CoV-2 refers to severe acute respiratory syndrome coronavirus
2 which was announced by ICTV (International Committee on
Taxonomy of Viruses) as the name of the new virus on 11 February
2020.
This name was chosen because the virus is genetically related to the
coronavirus responsible for the SARS outbreak of 2003. While
related, the two viruses are different.
COVID-19 is the name of this new disease announced on 11
February 2020, following guidelines previously developed with the
World Organisation for Animal Health (OIE) and the Food and
Agriculture Organization of the United Nations.
7. Clinical Features
Incubation period: 1-27 days
Recovery time: 3 weeks to 6 weeks
Frequently reported signs and symptoms of patients include:
Fever (77–98%)
Cough (46%–82%)
Myalgia or fatigue (11–52%)
Shortness of breath (3-31%)
Less commonly reported respiratory symptoms include sore
throat, headache, cough with sputum production
8. Diagnosis
Travel history to endemic countries like (China, Iran &
Italy)
CBC (leukopenia, seen in 30% to 45% of patients, and
lymphocytopenia, seen in 85% of the patients)
Chest X-Ray (cheaper & easier with 60% sensitivity)
PCR (30%-70% sensitivity)
Chest CT Scan (95% sensitivity, low specificity)
IgM/IgG combo test for COVID-19
10. Classification
Symptoms were categorized as follows:
Mild cases
The majority (81%) of these coronavirus disease cases were
mild cases include all patients without pneumonia or cases of
mild pneumonia.
Severe cases
This includes patients who suffered from shortness of breath,
respiratory frequency ≥ 30/minute
Blood oxygen saturation ≤93%, PaO2/FiO2 ratio <300,30
and/or lung infiltrates >50% within 24–48 hours.
Critical cases
Include patients who suffered respiratory failure, septic
shock, and/or multiple organ dysfunction or failure.
11. Risk of Infection
1. The Case fertility rate (CFR) was 0.9% for those without a
preexisting health condition & for young ages.
2. The CFR was 10% for those with underlying health
conditions & for old ages.
3. Fulminant myocarditis has also been reported in patients
with Covid-19 which is caused by virus. It arises quickly,
progresses rapidly, and may lead to severe heart failure or
circulatory failure presenting as rapid-onset hypotension
and cardiogenic shock, with mortality rates as high as
50%–70%.
4. Physicians should pay attention not only to the symptoms
of respiratory dysfunction but also the symptoms of
cardiac injury.
12. Management
No specific treatment for COVID-19 is currently available.
There are currently no antiviral drugs licensed by the U.S. Food
and Drug Administration (FDA) to treat patients with COVID-
19.
Clinical management includes prompt implementation of
recommended infection prevention and control measures and
supportive management of complications, including advanced
organ support if indicated.
Corticosteroids should be avoided in some cases, because of the
potential for prolonging viral replication as observed in MERS-
CoV patients, while its indication is mandatory in COPD
(chronic obstructive pulmonary disease)
14. Prevention
People can catch COVID-19 from others who have the virus.
The disease can spread from person to person through small droplets
from the nose or mouth which are spread when a person with COVID-19
coughs or exhales.
These droplets land on objects and surfaces around the person.
Other people then catch COVID-19 by touching these objects or
surfaces, then touching their eyes, nose or mouth.
People can also catch COVID-19 if they breathe in droplets from a
person with COVID-19 who coughs out or exhales droplets.
This is why it is important to stay more than 1 meter (3 feet) away from a
person who is sick.
15. Prevention
If someone sneezes with it, it takes about 10 feet before it drops to
the ground and is no longer airborne.
If it drops on a metal surface it will live for at least 12 hours
so if you come into contact with any metal surface , wash your
hands with a soap.
On fabric, it can survive for 6-12 hours. normal laundry detergent
will kill it.
Washing hands frequently as the virus can only live on hands for 5-
10 minutes, but a lot can happen during that time - you can rub
your eyes, pick your nose unwittingly and so on.
16. COVID-19 vaccine
The world is in the midst of a COVID-19 pandemic. As WHO and
partners work together on the response -- tracking the pandemic,
advising on critical interventions, distributing vital medical supplies to
those in need--- they are racing to find a vaccine.
There are currently more than 100 COVID-19 vaccine candidates
under development, with a number of these in the human trial phase.
WHO is working in collaboration with scientists, business, and global
health organizations through the ACT Accelerator to speed up the
pandemic response. When a safe and effective vaccine is
found, COVAX (led by WHO, GAVI and CEPI) will facilitate the
equitable access and distribution of these vaccines to protect people in
all countries. People most at risk will be prioritized.
