1 MeaNS, RubeNS and a global update
MeaNS, RubeNS and a global update Kevin Brown Virus Reference Department National Infection Service 22 June 2016

2 www.who-measles.org or www.who-rubella.org
MeaNS, RubeNS and global update 2016

3 MeaNS/RubeNS Bioinformatician Richard Myers – new post in 2015
Currently no-one in post Will be appointing to 2 posts Candidates selected and offers made David Williams: start August 2016 MeaNS, RubeNS and global update 2016

4 MeaNS and RubeNS – June 2016 MeaNS 28978 Sample Records
29822 Viral Sequences RubeNS 1590 Viral Sequences 4 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

5 MeaNS Submissions MeaNS, RubeNS and global update 2016

6 MeaNS Vaccine Sequences
There continues to be submission of MeV vaccine sequences to MeaNS 31 since the start of 2014 This is not what MeaNS was designed for and it would be better if people stopped doing this. There is a message to this effect, but still being ignored MeaNS genotypes sequences on entry so it would be possible to prevent submission of genotype A sequence, accompanied by a message that asking the submitter to contact us if there is good reason to submit – is it needed? 6 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

7 MeaNS Vaccine Sequences
Currently the N450 sequences for measles vaccine strains are in the named strains tool and will show up in searches Naming now makes it clear they are vaccine strains 7 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

8 WHO naming Sequences are stored according to WHO name Cannot have two different sequences with same WHO name Use naming convention as in WER WER 2 March 2012, No 9, vol 87 pp73-80 ie MVs/Newcastle under Lyne.GBR\16.16\ No commas, underscores, city or state (not both), no \1 if first sequence (When submitting to MeaNS or RubeNS no need to include genotype in the name) MeaNS will generate the name if you have the relevant information You cannot edit the WHO name once submitted. If there is a major error and it needs to be changed please send to MeaNS, with the justification. However: There are several different ways of generating Epi week in different countries. Additional epi data (ie week of onset instead of sample data) is not a justification of changing the name MeaNS, RubeNS and global update 2016

9 New sequence checking When sequences are submitted: New tool that will compare sequence to reference sequences Identify which coding region of the virus Then submit to the relevant fields If more than 1 field (ie total N, or whole genome) will populate all the relavent fields Currently in the trial database Will be imported into live database when bioinformatician in place MeaNS, RubeNS and global update 2016

10 Batch update – WHO submission sheet
It appears many labs are still using the old WHO submission sheet: This can be used for submitting sequences to MeaNS/RubeNS Need to paste the sequence into the spreadsheet. Please do not send sequences as a separate .fas file MeaNS, RubeNS and global update 2016

11 MeaNS submission by region
11 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

12 MeaNS by genotype 12 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

13 MeaNS Genotype Diversity
13 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

14 MeaNS Genotype Diversity
14 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

15 Distribution of measles genotypes year 2015
Note: Pie chart proportional to the number of sequenced viruses: China data has been adjusted by size (total genotyped = 2862). Data in HQ as of 7 March 2016 MeaNS, RubeNS and global update 2016

16 MeaNS Genotype Diversity
Genotype data in MeaNS appears to show a reduction in the number of genotypes At a WHO regional level: D8 and B3 dominate for most regions H1 skews the distribution in WPR Impact of sampling bias: Some countries submitting all data Some countries only unique sequences Some countries not sequencing at all 16 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

17 RubeNS Website Site is being used Submissions are limited
17 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

18 RubeNS Submissions Number of submission is increasing, but…..
18 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

19 RubeNS Submissions …majority coming from only one or two countries
19 Manual for the laboratory diagnosis of measles and rubella virus infection WHO – EPI, WHO/IVB/07.01: 2nd edition 2007 MeaNS, RubeNS and global update 2016

20 RubeNS genotypes MeaNS, RubeNS and global update 2016

21 Distribution of rubella genotypes year 2015
Data in HQ as of 7 March 2016 Note: Pie chart proportional to the number of sequenced viruses: China data has been adjusted by size (total genotyped = 255). and global update 2016

22 MeaNS and RubeNS Invaluable tools for monitoring transmissions Valuable tools for documenting importations/monitoring loss of endemic viruses within countries Large repository of data Can monitor the ‘disappearance’ of some measles genotypes Data is very heavily samples biased Even more sampling bias in RubeNS Talk on measles diversity on Thursday (S7 31) MeaNS/RubenS steering committee on Friday am All suggestions for ways to increase submissions especially for rubella sequences welcome MeaNS, RubeNS and global update 2016
