Discussion
Respiratory co-infections are common and simultaneous infections with
two viruses are accompanied by effects on the host and the synergism of
viruses. It will affect the immune response and outcome of the treatment
[2]. Common symptoms in patients with covid-19 and influenza
co-infections include fever, cough, and shortness of breath; Considering
the exact transmission mechanism of these two viruses, it is necessary
to perform appropriate and correct tests and timely diagnosis to
differentiate and proper treatment [6]. Furthermore, bacterial along
with viral infection can bring about other problems [5]. Hence,
appropriate diagnosis and treatment are vital for patient recovery and
suitable clinical outcomes. According to the results of a systematic
review study, co-infection with influenza and covid-19 may be associated
with a predisposition to secondary bacterial infection, which can
increase clinical outcomes [7]. In reported cases, COVID-19,
influenza co-infection and TB co-infection of case 1 along with
comorbidities and pregnancy represented situations entailing on-time
diagnosis and appropriate management. The dose and duration of the
effective treatment and monitoring of the patient’s symptoms and
conditions are other factors helping clinicians in achieving an optimal
clinical outcome.
