​​​​​​​​ 
Welcome to the influenza surveillance reporting website, brought to you by the Center for Infectious Disease Surveillance and Outbreak Response at the Maryland Department of Health (MDH).
CURRENT WEEK INFLUENZA ACTIVITY SUMMARY
During the week ending November 14, 2020 (MMWR Week 46), influenza-like illness (ILI) activity was MINIMAL.


​INFLUENZA SURVEILLANCE INDICATORS
ILI ACTIVITY:
One indicator we look at is the proportion of visits to sentinel providers for ILI. We compare these proportions to baseline numbers and then categorize ILI activity levels as minimal, low, moderate, high, or very high. 

 
PREDOMINANT INFLUENZA STRAIN:
A third indicator we look at is the predominant strain of influenza circulating in Maryland.  This is important because different strains have different implications for the community.  For example, a "novel" or "variant" strain will not have a vaccine available.  There are also some strains of influenza that have developed resistance to antiviral medication.  And there are some strains that will not match the strains in the seasonal flu vaccine.  Knowing what is circulating​ is important in planning and responding to influenza outbreaks.  Refer to the weekly report for a full breakdown of the PCR test results reported.​
