I have been working on leptospirosis  (a common zoonotic disease ) for the past 3 decades in India . Leptospirosis has emerged as an important infectious disease in Latin America & Asia . In India , it is under reported & under diagnosed due to lack of diagnostic facilities & lack of awareness of the disease . Leptospirosis has been reported from both rural & urban areas . Leptospirosis can present as asymptomatic infection ( which can be detected by sero-prevalence studies ) or symptomatic disease ( which is obtained by incidence rates ) . The rodents are the main reservoirs & they do not manifest any symptoms . They spread it to other animals such as cattle , dogs & pigs , which can have symptoms . All these animals can spread this to humans  Therefore , leptospirosis is also an occupational disease , especially farmers . My articles on leptospirosis are available in RG . Regarding the other diseases you have mentioned , data on epidemiology & clinical features are definitely inadequate .

For vector-borne zoonosis (such as P. knowlesi - an emerging zoonotic malaria), it really depends on the abundance of the vector species present, its bionomics, disease prevalence in animal hosts and human activity in the transmission area.  You can be in an area of high transmission between monkeys and its vector... but few (incidental) or no human cases if mosquitoes vectors present are highly simioacrodendrophagic (such as An. hackeri).  But if mosquitoes are both anthropo-simiophagic, then you would expect high disease incidence in humans.  In rice farming areas near the forest fringe, but mosquitoes are highly exophagic and "shy", you would expect to see more adult males patient than women and children.

Although much research has been done, I consider that the "occupational" dimension of zoonotic diseases has not been exhaustively studied for many zoonoses. Even more, there are some zoonoses that in certain countries are really neglected in terms of research. E.g. brucellosis in Colombia, you find only 13 articles in Medline; toxocariasis in Colombia, 6 articles, and so on. We need to enhance the importance of research in multiple zoonoses. You may be interested in an article we published 3 years ago:

Cascio A, Bosilkovski M, Rodriguez-Morales AJ, Pappas G. The socio-ecology of zoonotic infections. Clin Microbiol Infect. 2011 Mar;17(3):336-42. doi: 10.1111/j.1469-0691.2010.03451.x. (its freely available)

Several infectious diseases are caused by agents that directly or indirectly, are transmitted by different animal species to man. Currently more than 200 diseases that occur in humans and animals are mutually transmitted; These are caused by viruses, bacteria (including rickettsia and chlamydia), fungi, protozoa, helminths and arthropods. In 1958, the expert committee of the World Health Organization (WHO) defines zoonoses as "diseases and infections which are naturally transmitted between animals and man." This definition is still valid today (Krauss et al., 2003). In ancient Greece the term was referring generally to own animal diseases. In 1863, first, the word "zoonosis" received double meaning ("Etymological Dictionary of Medicine and Veterinary Sciences its auxilliary") "Zoonoses are animal diseases and human diseases from other animals by means of a vector, or contact ". However, there were also those who tried to derive the word by describing the direction of transmission, for example, "zooantroponoses" for diseases transmitted from animals to man and "antropozoonoses" for diseases transmitted from animals to man (Krauss et al. 2003). The most recent epidemiological knowledge questioned the traditional association of some infectious diseases zoonoses. Diseases that do not require an animal reservoir because they occur in water, soil and plants, but are transmitted to them (including humans), are called "sapronoses", "saprozoonoses" or "geonoses" (Krauss et al. 2003). The increased threat that represent zoonoses to man has many causes, including, vary from country to country. The overpopulation, wars and the gradual deterioration in the quality of life for some people lead to countless individuals migrating to the suburbs of large cities, with consequent "break" of hygiene and public health (Krauss et al., 2003).

I have been working on Rickettsiales diseases  (primarly Rickettsiosis, Ehrlichiosis and Anaplasmosis) for the last three years in Venezuela . Rickettsiales diseases has emerged as an important infectious zoonotic disease in Venezuela.  However  has been it is under reported and  under diagnosed due to lack of awareness of health personnel and are often confused with other tropical diseases such as dengue, hepatitis, yellow fever, malaria and leptospirosis.Our experience at Instituto Nacional de Higiene Rafael Rangel is that patients could be showed concomitants bewteen the three rickettsial diseases which is well documented and this is because some of these zoonosis share the same vector.
