Induced disease : Experimentally in 

 man, incubation period long, 4 weeks to 

 6 or more months ; initially acanthosis 

 (overgrowth of prickle cell laj'er of epi- 

 dermis) and flattening of the papillae; 

 later, interpapiliary hypertrophy, in- 

 flammation, and marked hyperkeratosis. 



Transmission : By contact ; in some 

 cases, venereally. Experimentally, bj^ 

 skin scarification. 



Filterabilit}^ : Passes Berkefeld N filter.

Arch. Dermat. u. Syph., 107, 1911, 395.) 

 From Latin homo, man. 



Common name : Molluscum contagiosum 

 virus. 



Host: HOMINIDAE— Homo sapiens 

 L., man. 



Geographical distribution : Perhaps es- 

 sentially world-wide. 



Induced disease : In man, experimen- 

 tallj^, prodromal period may be 14 to 50 

 days, lesions at first like pimples, becom- 

 ing red, painful, swollen, developing into 

 small tumors covered with stretched and 

 shiny skin; lesions commonest on face, 

 arms, buttocks, back, and sides, heal- 

 ing spontaneously. Inclusions within 

 epithelial cells, known as molluscum 

 bodies, measure 9 to 24 microns in diame- 

 ter when approximately spherical, 24 to 

 27 microns in width and 30 to 37 microns 

 in length when elongated; they contain 

 elementary bodies about 0.3 micron in 

 diameter. The outer envelope of the 

 molluscum bodj^ is of carbohydrate. 



Transmission: By contact. By 

 fo mites. 



Filterability : Passes Chamberland Li 

 and Berkefeld V filters.
