Follow SOP for filtering virus: remove capped needle from syringe, use syringe to draw up virus, filter. Then… because the syringe did not fit in the bottom of the tube… the needle was re-attached to draw the virus into the syringe. The needle had to be removed in order to replace the filter, and the researcher sustained a needlestick at that point.
The technician did self-testing; symptoms of dengue infection presented on day 9; the assay was positive on day 10.
Th th bli h d i i l ti th i id t d d d t The authors published images simulating the exposure incident, and recommended stronger language in the WHO advice on the use of needles.
After recovery, the technician was assigned to a different laboratory to prevent exposure to other serotypes of dengueserotypes of dengue.
