Influenza infection causes fever, chills, cough, headache, muscle aches, and pains in your back, arms, and legs.This essay will discuss the epidemiology of influenza A H1N1 in Mexico in 2009, personal characteristics of patients, patient time and place characteristics, treatment and prevention.
The virus was first identified in Mexico in 2009. It became known as swine flu because the virus closely resembled known influenza viruses that cause illness in pigs. In February 2009, a young boy in Veracruz fell ill with H1N1. Within weeks, 30% of the town’s residents had been affected by a similar sickness, and it spreads to nearby villages. He represented the first documented case known as “patient zero.” By mid-March a similar sickness emerged in Mexico City, and then cases of the respiratory illness were reported throughout the country. After several infected persons died, the health officials decided to send samples to a lab in Canada for analysis. When 16/50 of them turned up positive for swine flu, authorities at (WHO) convened an emergency meeting to assess the situation (1). …show more content…
Nevertheless, comparable with the year 2013-2014, the highest age group was patients between 31 and 40 years (Figure1) (2). Collectively, the 2009 H1N1 influenza was affecting younger age group in opposite to seasonal influenza which affects patients older than 65
