The hospital acquired computerviruses or HACs have been defined as computerviruses acquired in hospitals (see fig1).

The origin of computerviruses is unknown, although they are thought to have evolved from the coxsackieviruses by a process of mutation, rotation, recombination, translocation, dislocation, and extreme provocation.  


It was the best of times, it was the worst of times.


Computerviruses were cast forth upon the airwaves and upon the seawaves and upon the brainwaves. And some fell on hard disks and some fell on soft disks. But all were corrupted.

Clinical features

The hospital acquired computerviruses cause a severe diskitis with diffuse, widespread information.

Table 1 shows the different strains of computerviruses and their clinical features.

Computerviruses and their clinical features


The only agent with limited antiviral activity against the computerviruses is unicyclovir, which is altered by the computer to the active metabolites bicyclovir, tricyclovir, and recyclovir.


There is a vaccine made from organisms which are barely alive but attenuated, such as hospital administrators.
