Background and purpose: 

Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus were responsible for bacterial coinfection during previous or 2009 influenza pandemic and were associated with a higher risk of influenza-related morbidity and mortality. Despite tuberculosis (TB) is still a growing problem worldwide, Mycobacterial tuberculosis is rarely a copathogen with influenza. We hereby report a cancer patient with TB and pandemic H1N1 influenza A virus coinfection. Physicians should be aware that TB may present as a coinfection in an immunocompromised patient with 2009 influenza A (H1N1) infection, especially in TB endemic area.



 

Key words:

Coinfection, Mycobacterium tuberculosis, Pandemic influenza A (H1N1) virus
