Update on screening policy of blood donors to prevent Zika virus

In view of global Zika virus outbreaks have declined significantly and the implementation of the screening test for Zika virus, the pre-donation screening guideline has been revised by the Hospital Authority (BTS) Expert Panel on Blood and Blood Products Safety since 11 Mar 2019. Blood donors with the condition(s) listed below are no longer required to defer for blood donation:

 

In the past 28 days,

1) travelled to or resided in the Zika virus affected area

2) had sexual contact with a man who (from the date of last sexual contact)

  •  travelled to or resided in the Zika virus affected area in the past 3 months
  •  has been diagnosed with Zika virus infection

 

In order to enhance blood safety, the blood collected from these donors will be sent for Zika viral screening. While donors who had been diagnosed with Zika virus infection will still be required to defer for 180 days from the day of recovery.
