BACKGROUND: The COVID-19 global pandemic brought several challenges to occupational safety and health practice. One of these is the need to (re)assess the occupational risks, particularly, biological risks. OBJECTIVE: The purpose of this work is to promote guidance to occupational safety and health practitioners when conducting a biological risk assessment in this context. METHODS: The main steps of the biological risk assessment are explained with some inputs regarding the novelty posed by SARS-CoV-2 and an example of a qualitative risk assessment method is presented. Also, its application to two different activities was exemplified. RESULTS: In both cases, the assessment considered that vulnerable workers were working from home or in medical leave. The results showed low or medium risk level for the assessed tasks. For medium risk level, additional controls are advised, such maintain social distancing, sanitize instruments/equipment before use, use proper and well-maintained PPE (when applicable), and promote awareness sessions to spread good practices at work. Employers must be aware of their obligations regarding biological risk assessment and OSH practitioners must be prepared to screen and link the abundance of scientific evidence generated following the outbreak, with the technical practice. CONCLUSIONS: This paper could be an important contribution to OSH practice since it highlights the need to (re)assess occupational risks, especially biological risk, to ensure a safe return to work, providing technical guidance.

Armored RNA (AR) is a good candidate for creating nuclease-resistant RNA positive controls in the nucleic acid - based assay for RNA viruses. To simplify the production and purifcation of armored RNA, a single plasmid double – expressing His6-tag system was designed. His-tag armored RNA particles were purifed using his-tag affnity. A genomic fragment of the zika virus consisting of the encoding sequences of flavi-M, flavi-E-C protein targeted for zika virus was selected to prepare a positive control. In this study, we have successfully produced His-taged MS2- phage like particles carrying specifc genomic regions (M and E genes) to monitor the procedures of real-time Reverse transcription-PCR for Zika virus detection in one plasmid double expression. AR-ZIKA is completely resistant to DNase and RNase, stable in normal human EDTA plasma at room temperature for at least 60 and 15 days at 40C and room temperature respectively.
