Assignment details: Construct an epidemiological triad for an infectious disease. Define its common agent, reservoir, portal of exit, means of transmission, portal of entry, and host (the chain of infection). How long is its incubation period? Does it have a common source of outbreak? Does the CDC have active surveillance on this infectious disease? Does herd immunity apply? Is it pandemic?
Do this over influenza

Epidemiological triad for influenza
Common agent: influenza has common antiviral agents
Reservoir: The common reservoir of influenza virus A are the wild birds mostly shorebirds, ducks, and geese.
Portal of exit: influenza infectious agent uses a similar portal to get into and out of the host. It mostly uses the respiratory tract of the host and gets into the respiratory tract of the new host. It exits the respiratory tract by means of coughing and sneezing
Means of transmission: the influenza virus mode of transmission are the hands, surfaces, and droplets where they use it to gains entry.
Portal of entry: it refers to the way the pathogen gets admission into a susceptible host, for instance, the pathogen exits the respiratory tract of its source and gets into the respiratory tract of the new host.
Host (the chain of infection): during the circulation of the pathogen in humans, the virus usually gets accumulated into points of mutation in HA and NA which gives provision of it to escape the host immunity.
Incubation period: the incubation period of flu is generally between one and for days though it usually varies from one individual to the other. Therefore, the average incubation period for influenza is for two days.
Common sources of the outbreak: influenza virus usually have a common source epidemic where the period of exposure is relative, not long and in many instances occur within one incubation period.
CDC active surveillance: the influenza virus infections cannot be identified as a CDC agent as it is not nationally notifiable though it is reported in some countries. The local health institutions are required to follow strict guidelines on reporting its outbreaks.
Application of herd immunity: herd immunity applies to influenza as its notion is that when many people get the influenza vaccine, it assists in protecting the entire population. This is due to the reason that there are fewer infected people to transmit this contagious infection.
Is it epidemic: an influenza pandemic can be referred to as an epidemic of an influenza virus which generally spreads globally on a broader scale.
