So far we have narrowed down our 10 diseases to 4 possible infections. This includes :

• Rat bite fever

An infectious disease which develops after having been bitten or scratched by an infected rat or rodent.

• Cat Scratch Disease

This disease is trasmitted when a healthy individual has been scratched by an infected cat. This is especially so when playing with kittens.

• Leptospirosis

This disease can be transmitted through dogs or rodents. The bacteria involved is called Leptospira. It usually occurs in tropical country.

• Typhus

It can be transmitted by fleas, using cats, dogs, rats as a reservoir. The bacteria involved is called R. Typhi.

In general, we felt that these diseases are worth looking into as their symptoms were similar to the symptoms developed by the eldery man. These diseases also had a very good route for transmission compared to the other diseased.
