Abstract

BACKGROUND:

Although ZIKA virus infection is mainly transmitted through mosquito bite, it can also be transmitted through blood transfusion. More than 500,000 cases of ZIKA virus infection were reported in the Americas from 2015 to 2016. Up till now, over ten cases of imported zika virus infection have been reported due to frequent international exchanges in Shenzhen city of Guangdong Province, China. Unfortunately, there were no data on ZIKA virus infection in Chinese blood donors because it has not been included in routine screening for volunteer blood donors. As such, we performed a preliminary survey of the prevalence of ZIKA virus infection among volunteer blood donors in Shenzhen, China to assess the potential risk of ZIKA virus infection through transfusion.

STUDY DESIGN AND METHODS:

A total of 9,626 blood donor samples were collected and ZIKA RNA was detected by TMA nucleic acid amplification method with the Panther nucleic acid automatic analysis system of Spain GRIFOLS including Procleix ZIKA Virus Assay reagent. All experiments in this study were conducted in accordance with the standard operating procedure (SOP) of the blood center.

RESULTS:

Of the 9626 donor blood samples tested, None of these samples was ZIKV RNA reactive. There was no positive case from ZIKA Virus RNA screening in this preliminary survey.

CONCLUSION:

There was no ZIKA virus presence in blood donors in Shenzhen, China from this preliminary survey. The potential risk of ZIKA virus infection by transfusion is low in Shenzhen at this moment. Therefore there is no need to add ZIKA virus nucleic acid test as a routine screening for blood donors.

I am an Italian blogger, active since 2005 with main focus on emerging infectious diseases such as avian influenza, SARS, antibiotics resistance, and many other global Health issues. Other fields of interest are: climate change, global warming, geological and biological sciences. My activity consists mainly in collection and analysis of news, public services updates, confronting sources and making decision about what are the 'signals' of an impending crisis (an outbreak, for example). When a signal is detected, I follow traces during the entire course of an event. I started in 2005 my blog ''A TIME'S MEMORY'', now with more than 40,000 posts and 3 millions of web interactions. Subsequently I added an Italian Language blog, then discontinued because of very low traffic and interest. I contributed for seven years to a public forum (FluTrackers.com) in the midst of the Ebola epidemic in West Africa in 2014, I left the site to continue alone my data tracking job.
