Explanation:
The statement above is FALSE.
There are differences in the complex interactions that are formed with the host's system when a bacterial or viral infection occur and the two types of infection do not progress through similar sequences of events during immune response. The body system usually react to disease causing bacteria by increasing the local blood flow and signalling appropriate cells to attack the bacteria. For virus, virus are usually very adaptive to their host's system and therefore are very good at escaping the immune system. The body system has put in place many mechanisms to prevent this. The specific sequence of immune response depend on the type of virus and its interaction with the host cells.
