Influenza surveillance and targeted research studies are used to monitor the impact of influenza on different segments of the population (e.g., people in certain age groups, people with underlying medical conditions).
Does influenza need to be reported?

Is influenza airborne or droplet?
Influenza is thought to be transmitted primarily by droplets (particles ≥ 5 μm, and settling within 3-6 feet); however, the airborne route (particles < 5 μm remaining suspended in air) has been implicated in special situations, such as aerosol-generating procedures.
Does influenza require N95?
The researchers say their findings suggest that “anyone present in a room with a patient who has influenza might be at risk of exposure” and that properly fitted N95 respirators provide maximal protection.
How long is the incubation period for influenza?
While the general incubation period for the flu is usually between one and four days, this period can vary from person to person. The average incubation period for the flu is two days . This means that, on average, people start to develop flu symptoms about two days after coming into contact with the influenza virus.
What is sentinel surveillance Covid?
Sentinel surveillance is an efficient way to collect high-quality data in a timely manner systematically and routinely from representatives of the population under surveillance so that the information gathered can be applied to the population or among subpopulations at higher risk of developing severe disease.
What are the four 4 standard precautions for preventing and controlling infection in the clinical setting?
