Thus 
it  wil] 
1  be  seen 
that  from 
a  larg 
e  annual  mortality  from 
yellow  fever  in 
the  town  of  Flavana,  the  mortality  fell  to  nil,  as  the 
result  of  systematic,  scientific  measures  directed  against  the  mosquito 
alone. 
But  the  subsequent  history  is  still  more  interesting  :  — 
In  1902  the  American  Governor  had  handed  the  Administration 
over  to  the  Cubans  and  had  left  the  Island.  The  sanitary 
administration  evidently  then  gradually  became  lax,  anti-mosquito 
measures  were  not  carried  out  systematically,  and  in  November,  1905, 
the  first  case  of  yellow  fever  was  reported,  though  it  was  ascertained 
that  two  cases  had  occurred  in  October.  A  short  epidemic  followed, 
and  by  the  middle  of  February,  1906,  72  cases  with  23  deaths  had 
occurred,  and  up  to  June  30th,  1906,  82  cases  with  28  deaths. 
But  in  1907  the  United  States  again  took  over  the  Government, 
and  the  following  passage  occurs  in  the  Annual  Report  of  the  Public 
Health  and  Marine  Hospital  Service  for  1907. 
‘  Following  a  resolution,  the  administration  of  Cuban  affairs  again 
‘devolve  upon  the  Government  of  the  United  States.  From  a 
‘  sanitary  point  of  view  this  transfer  was  significant.  There  had  been 
‘  laxness  in  sanitary  work  in  the  interior,  and  many  districts  had 
‘  retrograded  to  deplorably  unhygienic  conditions,  requiring  attention. 
‘  Among  the  first  undertakings  of  the  new  regime  was  the  creation 
‘  of  an  efficient  sanitary  service,  supervised  by  an  officer  of  the  Army 
‘  Medical  Department . The  benefits  have  been  promptly  shown 
‘  in  the  elimination  of  yellow  fever  from  Havana.’
