Case Definitions for Pandemic Influenza H1N1
updated 19/04/10 Ministry of Health

The purpose of the case definitions below is to assist with:

• Public health or infection control responses
• National and international reporting

Ongoing surveillance will also pick up probable and confirmed cases, but has a greater emphasis on specific systems for influenza-like illness and hospitalisations for picking up resurgence and monitoring progression.

Confirmed case
A confirmed case of pandemic influenza A (H1N1) virus infection is defined as a person with laboratory confirmed pandemic influenza A (H1N1) virus infection by one or more of the following tests:

• Real-time RT-PCR
• Viral culture
• Four-fold rise in pandemic influenza A (H1N1) virus specific antibodies

Probable case
A probable case of pandemic influenza A (H1N1) virus infection is defined as a person with an influenza like illness* who has a strong epidemiological link to a confirmed case or defined cluster.

Close contact
Close contact is defined as having cared for, lived with or had direct contact with respiratory secretions or bodily fluids of a probable or confirmed case.

*Influenza-like illness: (i) history of fever, chills and sweating or clinically documented fever ≥38°C plus (ii) cough or sore throat.
