Natural History of Influenzas
The influenza virus was once called the Spanish Flu. This
was because at the end of May 1918, the King of Spain, King
Alfonso XIII, was the first to openly admit that a new disease
had emerged in their country (Mamelund, 2017). But the disease
did not originate in Spain. Other countries during that period
throughout Europe including the United States were
experiencing the so called “Spanish” Flu. Since World War I,
much has changed in terms of understanding the flu and the
origination of infectious disease. It is now known that the Flu is
caused by a virus. Statistical studies since 2000 have found that
higher mortality rates occur among the poor in comparison to
the more affluent (Mamelund, 2017). People who are more
susceptible to influenza are those who have poor nutrition, live
in overcrowded areas, have secondary infections like pneumonia
and other diseases (Mamelund, 2017).

Outbreak characteristics
According to the CDC, people who have the flu are most
contagious in the first 3 to 4 days after infection. People who
are healthy can start infecting others, 1 day before symptoms
develop and up to 5 to 7 days after getting sick (Influenza,
2018). In addition, some people can have the virus, have no
symptoms and spread it to others.
The World Health Organization’s Global Influenza
Surveillance and Response System was established in 1952
(Influenza, 2018). The purpose is to reduce the spread of
infection by vaccines. Based on the surveillance system,
Influenza activity in the United States remains low throughout
the summer months and early October. Outpatient illness
surveillance: The proportion of outpatient visits for influenza-
like illness remained low and was 1.4% which is below the
national baseline of 2.2%
