Influenza in ICD10: Difference between revisions

Line 25:

a person will be considered to have influenza if either of the following is true:

*i) 'ANY' lab test done for influenza was positive, or

*ii) the patient was believed, by the medical team to have influenza and is given a full course of treatment (which could possibly have concluded after leaving the hospital, or they could have died before completing the full course).

*ii) the patient was believed, by the medical team, to have influenza and is given a ''full course of treatment'' (which could possibly have concluded after leaving the hospital, or they could have died before completing the full course).

**'''NOTE'''

***a person can be diagnosed as having influenza even if no test was sent, OR EVEN when tests sent were negative if they meet criterion "(ii)".

***For (i) during flu season, "any lab test" means preliminary Cadham result or final Cadham result, or even the rapid swab done by the individual hospital labs.

=== What is a full course Antiviral Treatment?===

Oseltamivir (Tamiflu) or another anti-Flu agent is given for 5 days for mild disease.

*WHO and CDC however, recommend that in severe cases (including all cases requiring mechanical ventilation) the drug should be ''continued until the infection is resolved'' or ''there is satisfactory clinical improvement''.

===Off flu season===

*(before there is any reported flu in the province, and after the flu season has been declared to be over) a person can ONLY be diagnosed as having influenza '''only if the FINAL CADHAM result was positive'''.
