Abstract
Swine influenza is
respiratory disease of pigs caused by type A influenza virus
that causes regular outbreak in pigs. Human to human
transmission occurs. Some people develop severe
respiratory symptoms and need ventilator. Patients can get
secondary bacterial infections in form of pneumonia if viral
infections persist. Death of swine flu occurs due to
secondary bacterial infections leading to bacterial
pneumonias. Method : 369 patients having acute respiratory
illness suspected to be suffering from swine flu were
included. Real time reverse transcriptase polymerase chain
reaction (RT-PCR) was performed on sputum samples or
tracheal aspirates of 134 patients admitted in Hospital due
to pneumonia. 90 of these patients were positive for swine
flu by RT-PCR. Result : Among 90 patients 55 patients’
shows bacterial growth and 35 patients did not show any
growth. Maximum patients 17 shows Klebseilla
pneumoniae,17 show Staphylococcus aureus ,10 show
Escherichia coli,8 show Pseudomonas aeruginosa and 3
patients show Streptococccus pneumoniae. Even after
treatment, death of 36 patients occurred. Among these 36
patients, 19 had both, bacterial as well as swine flu infection
and 17 patients had only swine flu infection. Conclusion :
Secondary bacterial infections in swine flu patients were
multiresistant to antibiotics were noted. Pneumonia caused
by co-infection contributes to a severe rapidly progressive
illness.
