treated for the symptoms mentioned above. The
patients should be monitored for their progress and
reassessed at 24 to 48 hours by the doctor.
 No testing of the patient for Influenza is required.
 Patients should confine themselves at home and
avoid mixing up with public and high risk members
in the family.

Category B
 (i) In addition to all the signs and symptoms
mentioned under Category-A, if the patient has high
grade fever and severe sore throat, may require
home isolation and Oseltamivir;
 (ii) In addition to all the signs and symptoms
mentioned under Category-A, individuals having
one or more of the following high risk conditions
shall be treated with Oseltamivir:

Category B
 Children with mild illness but with predisposing risk
factors.
 Pregnant women;
 Persons aged 65 years or older;
 Patients with lung diseases, heart disease, liver
disease, kidney disease, blood disorders, diabetes,
neurological disorders, cancer and HIV/AIDS;

Vaccine
 While declaring the Pandemic to be over in August
2010, WHO conveyed that Pandemic Influenza A
(HINI) virus that caused Pandemic [2009-2010]
would circulate as Seasonal Influenza virus and
would continue to do so for years to come.
 WHO recommended vaccine only for High Risk Group
 Ministry of Health and Family Welfare recommends
the trivalent inactivated influenza vaccine.

Vaccine
 The ICMR has recommended on the following
Seasonal Influenza vaccine composition, for the
period 2017-2018. The recommended Trivalent
vaccine should have:
 an A/Michigan/45/2015 (H1N1)pdm09-like virus
 an A/Hong Kong/4801/2014 (H3N2) – like virus
 a B/Brisbane/60/2008-like virus

Vaccine
 The available vaccine takes about 2-3 weeks for
development of immunity. Hence for the health care
workers working in an environment with likelihood of
exposure to Influenza virus, vaccine should be
administered at least one month prior to the
commencement of the season, till such time use of
chemoprophylaxis may be considered.

chemoprophylaxis may be considered.

Limitations of the Influenza
Vaccination
 Influenza vaccination is most effective when
circulating viruses are well-matched with vaccine
viruses.
 Even with appropriate matching, efficacy of vaccine
may be about 70% to 80%.
 In case the locally circulating virus is different from
vaccine virus recommended by WHO, it may be
partially effective or not be effective at all.
 Hence, vaccine should not give a false sense of
security.

High Risk Groups for whom
vaccine is recommended by WHO
 Health Care workers, working in hospital / institutional
settings (doctors, nurses, paramedics) with likelihood
of exposure to Influenza virus
 Young children
 Pregnant women;
 Persons aged 65 years or older;
 Patients with Comorbidity
 Patients with compromised immunity

USE OF MASKS
 There are two types of masks which are recommended
for various categories of personnel depending upon the
work environment;
1. Triple layer surgical mask 2. N 95 Respirator
 Change the mask after six hours or as soon as they
become wet.
 Disposable masks are never to be reused and should be
disposed off.
 Never touch the potentially infected outer surface of
the mask while removing it.

USE OF MASKS
 There is no scientific evidence to show health benefit of
using masks for members of public. In fact erroneous
use of masks or continuous use of a disposable mask
for longer than 6 hours or repeated use of same mask
may actually increase risk of infection further.
 In the hospital setting used masks should be disposed
off in the identified infectious waste disposal
bag/container.
 In community settings, it may be disposed off either by
burning or deep burial.

Triple layer surgical mask
 Suspect/ probable/confirmed cases of influenza.
 The care provider in home care settings
 Close family contacts of such cases undergoing home
care should also use Triple layer surgical mask.
 All medical personnel (Doctor, nursing and paramedical
staff) would use Disposable Triple layer surgical mask
while interacting with patients in screening area.
 All patients, Medical and nursing staff in the isolation
wards.

Triple layer surgical mask
 Personnel involved in handling dead bodies of
suspect/confirmed cases (Mortuary)
 Ambulance Staff including driver.
 Doctors /Private practitioners with other health
workers in screening centres / general practice
 Health workers involved in community surveillance
 Security personnel working in an infected/ potentially
infected area for example Influenza ward in a hospital,
screening centre etc.

N 95 Respirator
 Staff involved in any aerosol generating procedures
like suction, intubation, nebulization, etc. they must
use N95 Respirator
 Medical personnel need to collect clinical samples from
patients.
 Medical personnel in ICU
 Medical personnel in laboratory

Tamiflu (Oseltamivir)
 Oseltamivir is the recommended drug for treatment.
Dose for treatment is as follows -
 By Weight:
 o For weight <15kg 30 mg BD for 5 days
 o 15-23kg 45 mg BD for 5 days
 o 24-<40kg 60 mg BD for 5 days
 o >40kg 75 mg BD for 5 days

Tamiflu (Oseltamivir)
 For infants:
 o < 3 months 12 mg BD for 5 days
 o 3-5 months 20 mg BD for 5 days
