SFV/NS 
+ Worked with SFV on open bench between 1949-1970 all experiments used animals; none used tissue cultu 
* Extensive exposure to SFV prior to joining lab; did not work with SFV in RES lab. 
• Known to be infected in 1959 with Mayaro Virus. 
SFV/NS: HI results indeterminate. Possibly due to weak SFV-specific antibody response or nonspecific 
crossreaction.
