Outcome of antiviral epidemic measures with various diagnosis delays and coverages.

Final symptomatic attack rate (as % of population) and peak daily symptomatic incidence (per 10,000) are given for different intervention strategies, diagnosis delays and diagnosis coverages. Intervention strategies are abbreviated as follows: T – antiviral treatment of diagnosed cases, H – prophylaxis of household of diagnosed cases, E – prophylaxis of school or work contacts of diagnosed cases, SC – four weeks of school closure. Where diagnosis delay differs from 24 hours, diagnosis coverage is 50%; where diagnosis coverage differs from 50%, diagnosis delay is 24 hours.
