Transfusion-transmitted infections(TTIs)impose meticulous screening protocols in blood banks.Emerging or re-emerging viruses with altered pathogenicity remains debatable whether or not to include those in TTI screening panel.Dengue infection is known to transmit via Aedes aegypti mosquito;however,the route of infection through blood transfusion is recently of greater importance.India with hyper-endemic and endemic dengue regions must guarantee the safety in transfusion-related products.The donor with asymptomatic dengue infection during viremic phase can act as a reservoir for transmission.The acute infection in dengue is ascertained by detecting either nonstructural-1 protein(NS1)or IgM antibody whereas the prevalence of dengue can be monitored by the presence of IgG.

S gene drop-out predicts super spreader H69del/V70del mutated SARS-CoV-2 virus

Asian Pacific Journal of Tropical Medicine 2021年第5期14卷 236-237页

Emergence of newer SARS-CoV-2 variants,especially strain B.1.1.7/SARS-CoV-2 VUI 202012/01,discovered in the United Kingdom with H69del/V70del mutation in spike S gene was reported with higher transmissibility of up to 70%[1].Identification of this variant was sparsely done in India because performing routine diagnosis as well as genomic surveillance using a single kit is the hour of need.To our knowledge,two publications identified the aforesaid mutation by phenomena called S gene drop-out using Applied Biosystems TaqPath COVID-19 Combo kit(Thermo Fisher Scientific,Waltham,USA)[2-4].

Lesson learned: Retrospective analysis of 'missed out' dengue NS1 positives among IgM negative population

引用

Asian Pacific Journal of Tropical Medicine 2020年第5期13卷 221-226页

Objective:To determine the proportion of dengue non-structural protein 1(NS1)positives among laboratory confirmed dengue IgM negative patients.Methods:Data for 1732 samples received from January to October 2017 at the Virus Research and Diagnostic Laboratory(VRDL)for dengue diagnosis were downloaded from the National Institute of Epidemiology server.Samples that were previously reported as IgM negative for dengue diagnosis were identified and their NS1 status was determined using ELISA.Thus,'missed out'NS1 positives were correlated with the duration of illness.Furthermore,an epidemic curve for the study period was constructed.The increase in positivity rate within and between the months was compared by McNemar's and Pearson's chi-square test,respectively.Results:The reported IgM-negatives were 813,of which,22.5%(183)were retrospectively positive for NS1 antigen.The addition of NS1 positives revealed by this study has raised the reported positivity across the months that ranged from 8.1%to 29.6%.By analyzing the dengue positives per month and the epidemic curve,the period between January and September,2017 was identified as non-epidemic while the epidemic started from the month of October,2017.Conclusions:Acute dengue infection is widely confirmed by detecting NS1 antigen in serum.Missing out of NS1 positives happen due to shortened window period and such cases act as reservoir for further viral transmission.Hence,this study highly emphasizes performing all three tests for dengue diagnosis that warrants the accurate dengue proportion in India.
