37˚C (50.87 %), heart rate of 81-90 bpm (44.73 %), respiratory rate of 18 breaths per minute (36.84 %),
normotension (76.31 %) and dry rales (16.66 %). Common flu was the most frequent diagnosis (46.49 %).
Conclusions: the suspected cases were mostly adult, with a history of good health and mild
symptomatology. At discharge other diseases were diagnosed, mainly common flu.
