Viruses are very small microorganisms, size range from 15 to 400 nm. Viruses cause a huge variety of diseases in animals, plants and humans. Viruses can be transmitted in diverse ways, when an infected person coughs by droplets, by contamination with stool samples, by sexual intercourse, by contact with blood, by contact with infected animals [1]. Bacterial and viral infections have a lot of things are in common. Both types of infections are caused by microbes (bacteria and viruses). Microbes cause coughing, sneezing, acute and chronic infections. Bacterial and viral infections also cause mild, moderate and severe diseases. Drews et. al, reviewed 1341 cases of respiratory viral infections detected with conventional techniques [2]. The mechanisms of bacteria and virus interactions were occurring either in the gastrointestinal tract or upper respiratory tract [3]. Bacterial and virus interactions are complex which results in enhanced pathogenesis and many papers have recognized the bacterial inhibition of viral infection [4]. Respiratory viruses follow recurring patterns of activity and cause pneumonia. Several viruses can be circulating at definite times of the year during the main epidemic peaks of one virus
