As an expert in the field of infectious diseases, I can provide you with information on the contagiousness of typhus. Typhus is caused by bacteria known as Rickettsia, which are transmitted to humans through the bite of infected fleas, lice, or ticks. The level of contagiousness depends on the specific type of typhus and the vector involved.

For example, epidemic typhus, caused by Rickettsia prowazekii, is transmitted through body lice, and can be highly contagious in crowded conditions where louse infestation is common. Endemic typhus, caused by Rickettsia typhi, is transmitted by fleas, which are more common in urban environments and among small animals, making it less contagious than epidemic typhus but still a public health concern.

It's important to note that typhus is not transmitted from person to person; the bacteria must be introduced into the bloodstream through a vector. However, the risk of infection can increase in areas with poor sanitation and in populations where vector control measures are not in place.
