Because they one of the dirtiest cockroaches, the risk of Oriental cockroaches spreading disease is fairly high if there is an infestation. These garbage eating bugs can spread E. coli and Salmonella along with many other diseases by crawling over eating utensils or food, causing diarrhea and other possible side effects. Allergies are also probable. The feces and saliva of the Oriental cockroach contain problematic proteins and allergens, which may trigger asthma attacks. In densely populated cities, scientists have identified a correlation between roach presence and the incidence of asthma. However additional studies are needed to determine the accuracy of this correlation.
