2009 H1N1

Info gathered by Mona Youssef

Page 2: 2009 H1N1 Documentary

Study has shown virus to be different from the normally circulating North American pig virus.

It has two genes from flu viruses that normally circulate in pigs in Europe and Asia , avian genes and human genes.

"quadruple reassortant" virus

How is it then that it made its first appearance in Mexico and the US?

Page 3: 2009 H1N1 Documentary

Genomic mapping of the virus revealed that it has been present and circulating in pigs for the past 7.5 to ten years (obviously undetected due to laxity in surveillance of pigs).

Page 4: 2009 H1N1 Documentary

Charecteristics

• Influenza virus can survive on environmental surfaces and remain infectious for up to 2-8 hours after being deposited on the surface.

• Virus is destroyed by:o heat 75-100 degrees Celcius.o chemical germicides: chlorine, hydrogen peroxide, detergents

(soap), iodophors (iodine-based antiseptics), and alcohols.

*wipes or gels with alcohol in them should be rubbed into hands

until they are dry.

A person can sneeze on someone’s luggage in an airport, and start an outbreak in a country without even entering it!

Page 5: 2009 H1N1 Documentary

Swine flu virus(Not novel H1N1)

• Like all influenza viruses, swine flu viruses change constantly.

• Pigs can be infected by avian influenza and human influenza viruses as well as swine influenza viruses.

• When influenza viruses from different species infect pigs, the viruses can reassort (i.e. swap genes) and new viruses that are a mix of swine, human and/or avian influenza viruses can emerge.

• Over the years, different variations of swine flu viruses have emerged. There are currently four main influenza type A virus subtypes that have been isolated in pigs: H1N1, H1N2, H3N2, and H3N1.

• Most of the recently isolated influenza viruses from pigs have been H1N1 viruses.

H3 subtypes infect older population and tend to be more severe.

Page 6: 2009 H1N1 Documentary

Drinking waterSwimming Pools and Spas

No completed research for novel H1N1 virus.

Research on H5N1 has shown:

• Free chlorine levels typically used in drinking water treatment are adequate to inactivate highly pathogenic H5N1 avian influenza.

• Free chlorine levels recommended by CDC to disinfect avian influenza A (H5N1) virus:

for swimming pools :1–3 parts per million

(ppm or mg/L)

spas: 2–5 ppm

It is likely that other influenza viruses such as novel H1N1 would also be similarly inactivated by chlorination.

Page 7: 2009 H1N1 Documentary

Dealing with the Deceased

• Transport of deceased persons does not require any additional precautions when bodies have been secured in a transport bag. Hand hygiene should be performed after completing transport.

• For deceased persons with confirmed, probable, or suspect novel influenza A (H1N1):o limit contact with the body in health care settings to close family

memberso Direct contact with the body is discouragedo Necessary contact may occur as long as hands are washed

immediately with soap and water.

NO need for mass burials yet….

Page 8: 2009 H1N1 Documentary

• Autopsy:o Standard Precautions.o Additional respiratory protection is needed procedures that

generate aerosols (e.g., use of oscillating saws). o minimize the number of personnel participating in post mortem

examinations.o Follow standard safety procedures for preventing percutaneous

injuries during autopsy.

WHO• April 24: 2009 H1N1 first disease outbreak notice.

• April 25: WHO Director General declares a formal “Public health emergency of international concern”

• April 27: “containment of the outbreak is not feasible” pandemic alert raised from phase 3 to phase 4.

• April 29: phase 4 to phase 5.

• June 11: phase 5 to phase 6.

During this time interim, the WHO was vastly criticized for not announcing

phase 6

A pandemic means an epidemic of an infectious disease, that spreads throughout a large number of people and can spread worldwide.

A pandemic begins when: there is person-to-person sustained transmission on multiple continents.

Page 15: 2009 H1N1 Documentary

The World Health Organization uses a six stage phase for alerting the general public to an outbreak

Page 16: 2009 H1N1 Documentary

Phase 1 – animal to animal transmission.

Phase 2 – an animal influenza virus is capable of human infection.

Phase 3 - small outbreaks among close populations but

not through human to human contact.

Phase 4 - Human to human transmission

Phase 5 - spread across two countries or more in one of the WHO regions (continents).

Phase 6 – spread across two countries or more in one of the WHO regions plus spread to another WHO region.

Page 17: 2009 H1N1 Documentary

W.H.O. identifies the following six epidemiological sub-regions.  

- African Region- Eastern Mediterranean Region- European Region- Region of the Americas- South-East Asian Region- Western Pacific Region

Page 28: 2009 H1N1 Documentary

In one week, the United Nations agency raised the alert level twice,

from phase 3 to phase 5, in response to the sustained transmission

of H1N1 in Mexico and the United States.

( 1976 swine flu Hsw1N1 outbreak never passed phase 3.

The vaccine developed caused 10 per million Guillain Barre

syndrome as compared to the 1-2 per million with the seasonal

flu vaccine and was banned.)

Consequences of a declaration of a full

pandemic

Institution of pandemic response plans, which may include measures affecting hospitals, schools or public events.

Provision of support for developing countries including: drugs, diagnostic tests, and medical staff

WHO is still expected to make an announcement to specify whether manufacturers should switch from making seasonal to pandemic flu vaccines.

Page 33: 2009 H1N1 Documentary

June 5 CDC Report:

Testing•CDC has developed a PCR diagnostic test kit for distribution throughout U.S. as well as internationally.

Vaccine •CDC has isolated the new H1N1 virus, for use as a candidate vaccine virus (Novartis manufactures first vaccine June 11 2009)

Strategic National Stockpile•CDC has deployed 25 percent of the supplies in the Strategic National Stockpile (SNS) to all states in the continental United States and U.S. territories. •This included antiviral drugs, personal protective equipment, and respiratory protection devices.

Previous Global Pandemics

Page 35: 2009 H1N1 Documentary

1918 - Spanish Flu (originated in birds).

First hit soldiers in Europe during World War I, as their immune systems were weakened by war.

The mortality rate was highest between 20 to 50 year olds. There was never any vaccine developed, after about 18 months, the virus seemed to just disappear.

The final death toll was written as 40 million people worldwide.

Many of the victims who have died in Mexico have been young and otherwise healthy.

Page 36: 2009 H1N1 Documentary

1957 - Asian FluThis flu started in birds in Asia.

In September schools and public places started closing in an effort to contain the virus.

In December the virus started to subside, but reappeared in January.

over two million people died

Reappeared

Page 37: 2009 H1N1 Documentary

1968 - The Hong Kong Flu

This is the mildest pandemic It was first found in the early months of 1968 in Hong Kong, and was declared a global pandemic by December.

Children were out of school and were therefore not able to spread it as much.

It made a mild reappearance in 1970 and 1972.

it claimed about a million lives

Seasonal influenza normally claims app. ¼ to ½ a million lives yearly.

Reappeared…!!!

Page 38: 2009 H1N1 Documentary

What we do know

Page 39: 2009 H1N1 Documentary

 Novel H1N1 virus tends to affect younger people just like the seasonal H1N1. (Older adults were shown to possess serum neutralizing antibodies to the new virus, most likely due to cross‐immunity with human H1N1 viruses. )

 

Novel H1N1 spreads just as easily as regular winter flu; ranging from very mild self-limited disease to Death.

Pandemic (H1N1) influenza virus continues to be the predominant circulating virus of influenza, both in the northern and southern hemisphere. All pandemic H1N1 2009 influenza viruses analysed to date have been antigenically and genetically similar to A/California/7/2009-like pandemic H1N1 2009 virus.

Page 40: 2009 H1N1 Documentary
Page 41: 2009 H1N1 Documentary

Seasonal flu vaccine production is to continue as is, in an attempt to reduce the chances of the viruses mingling together in the same environment.

Seasonal H1N1 virus that we've had this past year is resistant to Tamiflu.

Influenza is unpredictable.

Characteristics of reported cases of influenza A(H1N1) by country

Of note , the prevailing clinical picture in other countries has

been GIT related.

Page 43: 2009 H1N1 Documentary

Past Data limitations :

countries were using different surveillance methods and case definitions.

Caution must be exercised in interpreting information such as age as it may reflect patterns of travel or the occurrence of outbreaks in special settings such as schools.

Due to early stage of disease spread and the limited number of settings :

Incomplete picture of the epidemiological and clinical characteristics of the virus.

Estimates of important epidemiological parameters such as incubation period, attack rate and case fatality ratio may not be broadly applicable.

Page 44: 2009 H1N1 Documentary

The  objectives  of  on‐going  monitoring  of  influenza  activity  throughout  the  pandemic    

are  to  track:

global  geographical  spread  

disease  trend  

intensity  

impact  of  the  pandemic  on  health‐care  services  

the  number  of  deaths  due  to  acute  respiratory  disease   (by  age  group  if  available)  

changes  in  viral  antigenicity  and  antiviral  sensitivity.  

Page 45: 2009 H1N1 Documentary

Reporting  requirements    

• National  health  authorities  from  all  countries  should  inform  WHO  on  a  weekly  basis  of  their  qualitative  assessment  of  the  geogrphical  spread,  trend  of  cases,  intensity  of  disease,  impact  on  the  health‐care  system,  and  deaths.  

• National  health  authorities  from  countries  with  established  influenza  surveillance  systems  should  report  on  a  weekly  basis  data on  ILI  and/or  SARI  

• National  influenza  centres  or  reporting  laboratories  are  asked  to  report  weekly  via  FluNet  on  the  number  of  specimens  collected  and  processed  for  influenza  and  the  number  of  specimens  tested  that  are  positive  for  influenza  by  subtype.

VACCINE

Page 52: 2009 H1N1 Documentary

A review of 2009 production status for northern hemisphere seasonal vaccine indicates that:

Industry plans to produce approximately 480 million doses of trivalent seasonal vaccine in 2009.

Of this, 350 and 430 million doses will be available by 30 June and 31 July 2009, respectively.

For influenza A (H1N1), it is estimated that up to 4.9 billion doses could be produced over a 12‐month period IF there is initiation of a full‐scale production. In this situation, there is a potential access for the UN of supplies of up to 400 million doses.

A lot of Ifs……..

Page 53: 2009 H1N1 Documentary

Currently available data indicate that:

• Immunization with recent or shortly to be available trivalent seasonal vaccine is unlikely to provide public health benefits in terms of protection against influenza A (H1N1).

• Unknowns: optimal antigen content, the required number of doses, the required intervals between doses and the interchangeability of different products is currently unknown for

influenza A (H1N1) vaccines. the safety profile

Page 54: 2009 H1N1 Documentary

After considering the following issues:

1. the need for any recommendation to balance both risks and benefits,

2. the current uncertainty about the severity of influenza A (H1N1) illness,

3. the readiness of vaccine seed strains and reagents for large scale vaccine ‐production,

4. the current status of production of seasonal vaccine for the Northern hemisphere,

5. The risks associated with a premature cessation of seasonal vaccine production,

Page 55: 2009 H1N1 Documentary

•Two doses of vaccine may be needed.

•The combination of A (H1N1) vaccine with trivalent seasonal vaccine would have significant regulatory limitations.

•Moving into production now could result in starting vaccine production with strains of lower growth potential, as was the case for H5N1 A/Vietnam/2004. The yields were less than 50% of those usually obtained with seasonal vaccine viruses. (currently NH1N1 yields are 25% to 50 % of the normal yields for seasonal influenza)

• Using a poorly growing A (H1N1) virus could reduce global supplies of A (H1N1) vaccine.

The Working Group Declares that:

•It is premature to recommend commercial‐scale production of influenza A (H1N1) vaccine.

Page 56: 2009 H1N1 Documentary

The Working Group did make the following recommendations for immediate action:

(i)The WHO Secretariat, should recommend which vaccine viruses should be used for vaccine development as soon as possible

(ii) Essential reagents to calibrate antigenic content should be made available as a priority

(iii) The WHO Secretariat is encouraged to collaborate actively with its Collaborating Centres, Essential Regulatory Laboratories, and with industry, to assess the growth property of vaccine viruses and identify those with best growth potential, in order to maximize output of vaccine.

Page 57: 2009 H1N1 Documentary

(iv) Manufacturers are urged to develop clinical trial batches and accelerate initiation of clinical trials of influenza A (H1N1) vaccines and to start preparing for a potential future recommendation to move to commercial‐scale production.

(v) The above activities should not interfere with the present production of the Northern hemisphere seasonal vaccines

(vi) The number of needed doses of A (H1N1) vaccine will depend on the spread of influenza A (H1N1) virus in the next few weeks and on a better definition of the groups to be targeted

(vii) An evidence‐based recommendation for the groups to be targeted for vaccination still requires more data

Page 58: 2009 H1N1 Documentary

Medpage 7/24/2009 from an article written by Dr. Zalman S. Agus:

The FDA is likely to approve 2009 H1N1 (swine flu) vaccines before trial data can prove their safety and effectiveness against the virus.

Having a licensed vaccine doesn't mean that an immunization program will kick-off immediately -- that call has to come from the Secretary of Health and Human Services (HHS).

Page 59: 2009 H1N1 Documentary

• Of the five companies applying for FDA approval -- Novartis, sanofi pasteur, CSL Biotherapies, GlaxoSmithKline, and MedImmune -- only CSL has already started human trials. The Australian company, which provides seasonal flu vaccines to the U.S., inoculated its first human trial participant Wednesday.

• Meanwhile, the NIH announced it was set to begin clinical trials in the United States of vaccines made by sanofi-pasteur and CSL.

Page 60: 2009 H1N1 Documentary

If the vaccine is ineffective at stimulating an immune response, the FDA might have to issue an "emergency use authorization" for an oil-in-water adjuvant that sparks a stronger reaction in the immune system, but causes more side effects.

Two companies, GlaxoSmithKline and Novartis, are applying for approval for vaccines that contain oil-in-water adjuvants. The NIH is also conducting a trial of an adjuvant-enhanced vaccine.

Adjuvanted flu vaccines have been used for a decade in Europe and have not been shown to harm vulnerable populations, such as children.(Theodore Eickhoff).

The government has already purchased a supply of 120 million adjuvant doses that it will add to its antigen supply if it there is a shortage of the vaccine, or if the standard versions are shown to be ineffective.

Who is prioritized for treatment with influenza antiviral drugs?

Most people ill with influenza will recover without complications.  Some people are at increased risk of influenza complications and are prioritized for treatment with influenza antiviral drugs this season. They include:People hospitalized with suspected or confirmed influenza People with suspected or confirmed influenza who are at higher risk for complications:

Children younger than 5 years old (children under 2 years old are at higher risk for complications than older children) Adults 65 years and older Pregnant women People with certain chronic medical or immunosuppressive conditions

People younger than 19 years of age who are receiving long-term aspirin therapy

Physicians may also decide not to treat some people in these groups and/or treat people who are not in these groups based on their clinical judgment.

Page 82: 2009 H1N1 Documentary

• drink clear fluids (such as water, broth, sports drinks, electrolyte

beverages for infants) to keep from being dehydrated

• cover coughs and sneezes. Clean hands with soap and water or an

alcohol-based hand rub often and especially after using tissues and

after coughing or sneezing into hands.

• avoid close contact with others – do not go to work or school while ill

Steps to Lessen the Spread of Flu in the Home

Page 89: 2009 H1N1 Documentary

• Stay informed.

• Follow the cough etiquette and teach and model it to your children:

Cover your nose and mouth with a tissue when you cough or

sneeze.

Throw the tissue in the trash after you use it.

Wash your hands often with soap and water, especially after

you cough or sneeze. Alcohol-based hand cleaners are also

effective.

Avoid touching your eyes, nose or mouth. Germs spread this

way.

Try to avoid close contact with sick people.

Page 90: 2009 H1N1 Documentary

• Stay home for 7 days after your symptoms begin or until you have

been symptom-free for 24 hours, whichever is longer.

• Keep away from other household members as much as possible. This

is to keep you from infecting others and spreading the virus further.

• Provide each family member with their own hygienic necessaties eg

towels…

Page 91: 2009 H1N1 Documentary

Placement of the sick person

Page 92: 2009 H1N1 Documentary

• Keep the sick person in a room separate from the common areas of

the house. For example, a spare bedroom with its own bathroom,to be

cleaned daily with household disinfectant.

• Keep the sickroom door closed.

• Have the sick person wear a surgical mask if they need to be in a

common area of the house near other persons.

Stay away from the

alien virus invasion!

Page 93: 2009 H1N1 Documentary

Protect other persons in the home

Page 94: 2009 H1N1 Documentary

• The sick person should not have visitors other than caregivers. A

phone call is safer than a visit.

• If possible, have only one adult in the home take care of the sick

person.

• Avoid having pregnant women care for the sick person.

• Maintain good ventilation in shared household areas (e.g., keeping

windows open in restrooms, kitchen, bathroom, etc.).

Page 95: 2009 H1N1 Documentary

If you are the caregiver

Page 96: 2009 H1N1 Documentary

• Avoid being face-to-face with the sick person.

• When holding small children who are sick, place their chin on your

shoulder so that they will not cough in your face.

I didn’t believe them when they said that smoking was bad for my health… a risk factor for novel H1N1!

Page 97: 2009 H1N1 Documentary

• Avoid close contact (less than about 6 feet away) with the sick person

as much as possible.

• Spend the least amount of time possible in close contact and try to

wear a facemask (for example, surgical mask) or N95 disposable

respirator(it is harder to breathe through an N95 mask for long periods

of time)

Get in, get out…

Page 98: 2009 H1N1 Documentary

• Clean your hands with soap and water or use an alcohol-based hand

rub after you touch the sick person or handle used tissues, or laundry.

• Talk to your health care provider about taking antiviral medication to

prevent the caregiver from getting the flu.

• Monitor yourself and household members for flu symptoms and

contact a telephone hotline or health care provider if symptoms occur.

Page 99: 2009 H1N1 Documentary

Using Facemasks or Respirators

Page 100: 2009 H1N1 Documentary

• Facemasks and respirators may be purchased at a pharmacy, building

supply or hardware store (not off the street).

• Used facemasks and N95 respirators should be taken off and placed

immediately in the regular trash so they don’t touch anything else.

• Avoid re-using disposable facemasks and N95 respirators if possible.

If a reusable fabric facemask is used, it should be laundered with

normal laundry detergent and tumble-dried in a hot dryer.

• After you take off a facemask or N95 respirator, clean your hands with

soap and water or an alcohol-based hand sanitizer.

Page 101: 2009 H1N1 Documentary

Household Cleaning, Laundry, and Waste Disposal

Page 102: 2009 H1N1 Documentary

• Throw away tissues and other disposable items used by the sick

person in the trash.

• Wash your hands after touching used tissues and similar waste.

• Keep surfaces (especially bedside tables, surfaces in the bathroom,

and toys for children) clean by wiping them down with a household

disinfectant according to directions on the product label.

• Eating utensils should be washed either in a dishwasher or by hand

with water and soap.

Page 103: 2009 H1N1 Documentary

• Linens, eating utensils, and dishes belonging to those who are sick do

not need to be cleaned separately, but importantly these items should

not be shared without washing thoroughly first.

• Wash linens (such as bed sheets and towels) by using household

laundry soap and tumble dry on a hot setting.

• Avoid “hugging” laundry prior to washing it to prevent contaminating

yourself.

• Clean your hands with soap and water or alcohol-based hand rub right

after handling dirty laundry.
