Interim Health advisory on the 2019 Novel Coronavirus (2019-nCoV)

Interim Health advisory on the 2019 Novel Coronavirus (2019-nCoV)

The World Health Organization (WHO) says , ‘Not enough is known about 2019 Novel Coronavirus (2019-nCoV) to draw definitive conclusions about how it is transmitted, clinical features of disease, or the extent to which it has spread. The source also remains unknown’

The following information is based upon interim draft guidelines and is subject to change as and when newer recent information is received.

According to WHO, a new type of coronavirus (2019 novel coronavirus, nCoV) has been identified in China on 7 January 2020. The cluster of patients with pneumonia – like – illness was initially reported on 31 December 2019.

What is the nCoV ?

Coronaviruses are a family of respiratory viruses, named for the crown-like spikes on their
surface. Coronaviruses can cause diseases ranging from the common cold to the Middle-East
Respiratory Syndrome and the Severe Acute Respiratory Syndrome (SARS). The Novel coronavirus, nCoV is a new strain of coronavirus that has not been previously identified
in humans. They are notorious for mutating quickly and acquiring new qualities.

What are the Symptoms and Signs of infection with Novel coronavirus, nCoV ?

The symptoms reported are mainly fever, with a few having difficulty in breathing. Chest Xrays
are showing invasive pneumonic infiltrates in both lungs. This cannot be differentiated
from other respiratory infections excepting a history of travel to affected geographical area.

What is the course of Illness ?

As of now, more than 41 cases with novel coronavirus infection have been preliminarily diagnosed in Wuhan City of China. Of the 41 cases reported, two deaths have been reported and at least one of the patient had other underlying health conditions. While seven are severely ill, six patients have been discharged from hospital. Cases have been identified in countries such as Japan , Thailand and USA .The risk of cases being reported form elsewhere is increased, especially considering heavy population movements during the Chinese New Year in the last week of January.

How is the infection transmitted ?

The transmission potential and modes of transmission as of now remain largely unclear.
The evidence is highly suggestive that the outbreak is associated with exposures in one seafood
market in Wuhan. Most of the cases affected worked at or were handlers and frequent visitors
to the Huanan Seafood Wholesale Market. Preliminary epidemiology also suggests an animal source and thus a zoonotic disease .At this stage, there is no clear evidence but high suspicion of limited human to human transmission of infection. No case has been reported as yet among healthcare workers.

What are the criteria for Evaluation of Patients Under Investigation (PUI) for 2019-nCoV (Source- CDC 2020) ?

• Fever and symptoms of lower respiratory illness (e.g., cough, difficulty breathing)
  and in the last 14 days before symptom onset, a history of travel from Wuhan City, China
• In the last 14 days before symptom onset, close contact with a person who is under investigation for 2019-nCoV while that person was ill.
• Fever or symptoms of lower respiratory illness (e.g., cough, difficulty breathing)
  and in the last 14 days, close contact with an ill laboratory-confirmed 2019-nCoV patient.

Fever may not be present in some patients, such as those who are very young, elderly, immunosuppressed, or taking certain fever-lowering medications. Clinical judgment should be used to guide testing of patients in such situations.

Close contact is defined as—

a) being within approximately 6 feet (2 meters), or within the room or care area, of a novel
coronavirus case for a prolonged period of time while not wearing appropriate personal
protective equipment (e.g., gowns, gloves, N95 respirator, eye protection).
Close contact can include caring for, living with, visiting, or sharing a health care waiting area or
room with a novel coronavirus case.

or b) having direct contact with infectious secretions of a novel coronavirus case (e.g., being
coughed on) while not wearing appropriate personal protective equipment.
