Research Model for the SARS Epidemic Constructed A research model for the SARS epidemi c in Hong Kong was constructed by Prof . Wong Tz e Wa i an d Dr . L i u Hongji e o f th e University's Departmen t o f Communit y an d Family Medicin e an d Dr. Jame s Derric k o f the Prince o f Wales Hospital. Th e model ca n be use d t o explai n th e natura l cours e o f a n epidemic ─ th e relationshi p betwee n th e infected, susceptible and immune populations , and ho w th e natura l progressio n o f a n epidemic i s affecte d by effectiv e an d timel y public healt h measures. The model also helps to predict the likelihood o f the resurgence o f SARS i n the community . Major finding s o f th e SAR S epidemi c model include : · I f the epidemic i s allowed to die down by itself, a significan t proportio n o f th e population w i l l hav e t o fal l victi m t o SARS, for only through this can sufficient herd immunity be acquired to protect the community fro m furthe r epidemics . · A n epidemic will die down only when the basic reproductiv e numbe r (numbe r o f people infecte d by a patient) i s les s tha n one. Thi s ca n be achieve d i n tw o way s 一 whe n her d immunit y i s hig h enoug h (natural cours e o f events) , o r whe n effective public healt h measures limit the spread o f th e epidemic . Hon g Kong' s current basic reproductive numbe r i s less than one .
