INTRODUCTION
Covid 19 causes acute respiratory syndrome.
The first case was reported in Wuhan,China in
December 2019.
The disease spreaded world wide and became
pandemic.
Hosts, Reservoirs and Infected
Animals
Infect birds and mammals.
Bats are hosts to the largest number of viral genotypes of
coronavirus.
Epidemics can occur when viruses transmit from one
species to another.
Can cause mutations in proteins that allow viruses to bind
to cells.
Humans
Human coronaviruses are causes of respiratory and
gastrointestinal tract infections.
Estimated to account for 5-10 percent of all adult upper
respiratory tract infections (“common cold” to pneumonia and
ARDS).
GI symptoms including diarrhea.
When mutations occur, coronaviruses can be a significant
cause of human epidemics.
INCUBATION PERIOD
The incubation period of COVID-19, which is
the time between exposure to the virus and
symptom onset, is on average 5-6 days, but
can be as long as 14 days. Thus, quarantine
should be in place for 14 days from the last
exposure to a confirmed.
DIAGNOSTIC TESTS
Antibody (Serology) Tests
What they do: These tests detect antibodies that signal that
the body has mounted an immune response to the virus.
They do not indicate whether a person has current COVID-
19 infection, or when they were exposed.
Method: Blood Sample
Molecular Tests
What they do: These tests loo for the virus’s genetic
material and are the current standard for diagnosing COVID-
19.
Method: Nasal or throat swab, and for some test, saliva.
COVI
D-19 SYMPTOMS
Fever or chills
Cough
Shortness of breath or difficulty in breathing
Fatigue
Muscle or body aches
Headache
New loss of taste or smell
Sore throat
Congestion or runny nose
Nausea or vomiting
Diarrhea
TREATMENTS
There is no specific, effective treatment or cure for corona viruses’ disease
2019 (COVID-19) the disease caused by the SARSCOVID-2 virus.
But in India “Covishield” and “Covaxin” were used in this time.
The “Oxford –AstraZeneca” vaccine has been approved for use
in the UK. There is no vaccine approved by WHO.
PREVENTION
Wash hands even if they are visibly clean.
To cover your nose and mouth with
handkerchief/tissue while sneezing and coughing.
To throw used tissues into closed bins
immediately after use.
To maintain a safe distance from persons during
interaction, especially with those having flu-like
symptoms.
