2. What is Coronavirus? How is the strain
causing outbreak different?
Coronaviruses -large family of RNA
viruses
Structure -petal shaped spikes
surrounding the virus and resembling the
‘solar corona’, hence the name.
They mostly infect animals, including
camels, cattle, cats and bats.
2019- Novel Coronavirus belongs to
group of newer Human Coronaviruses
including SARS, MERS which have evolved
and infect and spread amongst humans
usually causing severe respiratory illness
and outbreaks.
3. Current Outbreak: When and where did it
start?
On 31st December 2019, WHO was alerted to several
cases of pneumonia in Wuhan City, Hubei Province of
China of unknown etiology
31st Dec 2019 – 3rd Jan 2020: 44 cases with pneumonia
of unknown etiology in China
7th Jan 2020 : China isolated a new type of coronavirus
12th Jan 2020: China shared the genetic sequence of the
new coronavirus which did not match any other known
virus
Temporarily named “2019-nCoV.” 2019- novel
coronavirus

7. MODE OF SPREAD:
Initially, many cases had some link to a
large seafood and animal market,
suggesting animal-to-person spread.
However, now It is suggested that
person-to-person transmission might
be occurring
The exact mode of human to human
transmission of the 2019-nCoV is not
known
It is thought to be similar to
Influenza, SARS, MERS i.e. commonly
through respiratory droplets
produced when an infected person
coughs or sneezes
8. CLINICAL SIGNS AND SYMPTOMS
For confirmed 2019-nCoV infections,
reported illnesses have ranged from
infected people with little to no
symptoms to people being severely ill
and dying.
Symptoms can include: Fever, Cough,
Shortness of breath.
In severe illness: Severe Acute
Respiratory illness, Pneumonia, Renal
failure, Death
Symptoms of 2019-nCoV may appear in
as few as 2 to 14 days after exposure
9. PREVENTION
There is currently no vaccine to prevent
2019-nCoV infection.
The best way to prevent infection is to avoid
exposure and preventing transmission:
Avoid all non essential travel to China.
Observe good personal hygiene.
Wash your hands often with soap and water
for at least 20 seconds. If soap and water are
not available, use an alcohol-based hand
sanitizer.
Avoid touching your eyes, nose, and mouth
with unwashed hands.
Avoid close contact with people who are sick.
Stay home when you are sick.
10. Observe respiratory etiquettes-
While coughing or sneezing
cover mouth and nose with
flexed elbow or tissue, then
throw the tissue in the trash.
Clean and disinfect
frequently touched objects
and surfaces.
11. Food Safety
Avoid direct unprotected contact
with live animals
The consumption of raw or
undercooked animal products should
be avoided
13. Infection Prevention and Control Measures
Should be initiated at first point of contact with a
suspected patient
All Standard precautions need to be undertaken:
HAND HYGIENE
USE OF PPE Personal Protective Equipment
SHARP INJURY
WASTE MANAGEMENT
DISINFECTION
APPLY DROPLET PRECAUTIONS
APPLY CONTACT PRECAUTIONS
APPLY AIRBORNE PRECAUTIONS – when performing Aerosol
Generating Procedure
14. Words of Wisdom on Hand
Washing
Soap, water and
Common sense are still
the Best Antiseptics
William Osler
15.
16. • The use of protective gears should be
made mandatory for all the personnel
if chances of close contact with
suspected or diagnosed patient is
anticipated/inevitable.
N-95 masks only to be used for people
who are likely to come in close
contact with the patient(One meter)
or while taking samples or doing
procedures which can generate
aerosols.
Make sure the mask fits properly( Do
a fit test)
Personnel Protective Equipment( PPE)
17. At TRIAGE
Give suspect patient a medical mask
Direct patient to a separate earmarked isolated area
Keep atleast 1 meter distance between suspected and
other patients
Instruct all patients to cover nose and mouth during
coughing/ sneezing
Perform Hand Hygiene
18. DROPLET PRECAUTIONS
Use medical Mask if working within 1-2 meters of
patient
Place patients in single room or group in one room
if same etiological diagnosis with spatial
separation
When providing patient care in close contact –
wear Mask
19. Airborne Borne Precautions
When performing aerosol generating
procedures Use PPE
Adequately ventilated isolated single rooms
Avoid crowding or unnecessary personnel in
room.
20. SPECIMEN COLLECTION
Samples should be collected as soon as possible.
Wear proper PPE including N95 Mask
Samples acceptable:
Oropharyngeal swab
Nasopharyngeal swab
Nasal aspirate
combined nasopharyngeal swab with oropharyngeal swab
For patients who are intubated, an endotracheal
aspirate/Bronchoalveolar lavage (BAL)
Sputum specimens are also acceptable but not preferred.
Tissue Biopsy
Serum samples( paired serum sample Acute/ Convalescent
phase 4 weeks apart)
21. Collection of Oropharyngeal swab
Instructions for collection:
Adequate view of the throat should be ensured
by good lighting.
Disposable wooden spatula should be used to pull
outwards and to depress the tongue.
Swab: Dacron coated sterile swab on a stick
Swab should be rubbed with rotation over one
tonsillar area, arch of soft palate and uvula, the
other tonsillar area and finally the posterior
pharyngeal wall.
22. Nasopharyngeal swab
Tilt head backwards Insert flexible fine- shafted
polyester swab into nostril and back to
nasopharynx
Leave in place a few seconds
Withdraw slowly; rotating motion
Nasal swab
A nasal swab is taken to detect healthy carriers
Nasopharyngeal aspirate
Tilt head slightly backward Instill 1-1.5 ml of
VTM/sterile normal saline into one nostril
Use aspiration mucus trap Insert silicon catheter in
nostril and aspirate the secretion gently by suction
in each nostril
23. PACKAGING AND TRANSPORT
The heads of swabs are broken of into tubes of viral
transport medium (VTM).
Three layer packing to be done as per guidelines
Use ice packs in a sealed box for transport
Labelling and fill referral form as per NIV pune
Transport as soon as possible.
Courier service number as provided by NIV pune.
Pre inform State nodal officer and Nodal officer NIV
Pune contact details as provided on their website
If delay for ˃24 hrs., refrigerate at 4°C
The swab should be replaced in its tube with care
not to soil the rim
If Delay in transport can be kept at 4°C for 72 hrs.
or at -20°C no longer than 4 days.

Editor's Notes
Use of a pair of disposable gloves can protect if chances of contact with Blood or Body fluid is anticipated/inevitable.
Use of Mask, Cap, Eye Wear, Will certainly protect us from splashes of Blood or Body fluids.
Wearing foot wear covering entire sole protects the entry of Microbes from the contaminated floors with Blood and Body fluids.
