RESUMO
Coliphage T3 was inactivated by a factor of 103 to 104 within 30 min after spraying from solutions of NaCl. Addition of peptone to the spray medium protected against inactivation at high relative humidity (RH), presumably by preventing surface inactivation. Prehumidification of the sample before collection had no effect on recovery if sprayed from solutions of NaCl, with or without peptone. If only peptone was present in the spray medium, prehumidification of the aerosol sample increased the recovery by a factor of 1,000 at low RH and by a factor of 5 at high RH. In aerosols sprayed from saliva, inactivation was nearly equal to that in peptone, with an increase of recovery after prehumidification by a factor of 1,000.
