The most recent aVDPV2 positive environmental sample was collected on 10 April 2020. 3. SOMALIA: No new VDPV cases or positive environmental samples reported this week. In 2020 to date: No cVDPV2 cases. There are 13 cVDPV2 positive environmental samples reported, the most recent collected on 19 May 2020. IV. Surveillance performance indicators In 2020, 12 out of 22 member states are meeting the global target of both key surveillance indicators, namely non polio AFP rate of 2 per 100,000 children aged below 15 years and percent AFP cases with adequate specimen 80% and above. This compares with 19 countries meeting the both indicators in the same period in 2019. There is a decline in reporting of AFP cases due to COVID-19 Pandemic. ▪ Djibouti is missing both indicators and has not reported any AFP case in 2020 to date. ▪ Morocco and Tunisia are, also, missing both indicators as their non-polio AFP rate is 1.4 for both countries and their percentage of AFP cases with adequate stool specimens is 66.7% and 61.9%, respectively. ▪ Egypt, Jordan, Oman, Palestine, Qatar and Saudi Arabia have a non-polio AFP rate of 1.9, 1.0, 1.7, 0.7, 0.4, and 1.3 respectively. ▪ Note: Sudan has a non-polio AFP rate of 1.7 in this analysis which does not include few cases reported at the state level but not included in the country line-list communicated to POL EMR due to operational reasons. Per country team’s latest weekly report, it is 2.1. Efforts are afoot to deal with this inconsistency. 3 World Health Organization – Regional Office for Eastern Mediterranean AFP SURVEILLANCE 27-Jul-20 Week 30, ending 26 July 2020 Number 1138 Table 1: Acute Flaccid Paralysis (AFP) cases by week of onset Reported AFP cases by week of onset - Week (30/20) / Ending on : 26/07/2020 Country 2018 2019 2020 to to date, Total Total AFP Total AFP Total AFP W19 May 20 10 W20 May 20 17 W21 May 20 23 W22 May 20 31 W23 7 Jun 20 W24 Jun 20 14 W25 Jun 20 21 W26 Jun 20 28 W27 5 Jul 20 W28 Jul 12 20 W29 Jul 19 20 W30 Jul 26 20 Afghanistan 3378 3768 1922 63 57 34 53 71 82 79 92 87 83 62 10 Bahrain 35 17 10 0 1 1 0 0 0 0 0 0 0 0 0 Djibouti 0 5 0 0 0 0 0 0 0 0 0 0 0 0 0 Egypt 1246 1343 421 15 18 1 7 22 18 10 0 0 0 0 Iran 896 1070 322 8 14 16 8 10 8 7 8 6 0 2 0 Iraq 1023 1157 270 7 8 2 6 4 6 8 2 2 4 3 Jordan **** 115 113 22 0 0 0 0 2 0 1 0 0 0 Kuwait 72 48 18 0 0 1 0 0 1 1 2 0 0 0 Lebanon **** 89 87 28 0 0 1 0 2 0 0 0 0 0 0 Libya 122 107 57 1 1 1 2 1 1 1 0 3 3 0 Morocco 212 247 72 2 0 1 2 3 2 0 3 1 2 0 Oman 28 30 11 0 1 0 0 0 1 0 0 0 0 0 0 Pakistan 12276 15216 6025 173 173 125 162 178 143 138 123 130 127 37 0 Palestine **** 44 62 8 0 0 0 0 0 0 0 0 1 0 0 Qatar 10 9 1 0 0 0 0 0 0 1 0 0 0 0 Saudi Arabia 242 236 64 0 0 0 2 4 2 0 2 0 0 3 0 Somalia 353 361 207 3 6 6 5 7 7 10 3 2 2 1 Sudan 579 608 179 0 3 1 2 4 5 4 5 4 6 0 0 Syria **** 362 377 215 8 6 7 5 10 22 4 11 10 8 3 1 Tunisia 68 79 21 0 1 2 0 0 2 0 2 0 0 0 U.A.E 40 50 15 0 0 0 1 1 0 0 1 0 1 0 0 Yemen 730 779 357 9 5 7 10 9 8 8 15 16 12 13 Total EMR 21920 25769 10245 289 294 206 265 328 308 272 269 262 248 124 11 No data = No report received Table 2: Confirmed polio cases by month of onset 26/07 Confirmed polio cases by month of onset Country 2019 2020 May May July July 2019 2019 2019 2019 2019 2020 2020 2020 2020 2020 2020 2020 April June June March March August August January January October October February February December December November November September September Total year 2018 Total year 2019 Total year Afghanistan 21 29 15 34 2 3 1 7 1 2 3 7 12 10 Bahrain 0 0 0 0 0 0 0 0 0 0 0 Djibouti 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Egypt 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Iran 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Iraq 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Jordan **** 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Kuwait 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Lebanon **** 0 0 0 0 0 0 0 0 0 0 Libya 0 0 0 0 0 0 0 0 0 0 0 0 0 Morocco 0 0 0 0 0 0 0 0 0 0 0 Oman 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Pakistan 12 147 55 60 14 5 17 23 32 18 17 7 6 6 6 Palestine **** 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Qatar 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Saudi Arabia 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Somalia 0 0 0 0 0 0 0 0 0 0 0 Sudan 0 0 0 0 0 0 0 0 0 0 0 Syria **** 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Tunisia 0 0 0 0 0 0 0 0 0 0 0 0 0 U.A.E 0 0 0 0 0 0 0 0 0 0 0 0 0 Yemen 0 0 0 0 0 0 0 0 0 0 Total EMR 33 176 70 94 16 8 18 30 33 20 20 14 6 18 16 0 **** UNRWA cases are included with those of country of residence World Health Organization – Regional Office for Eastern Mediterranean 4 AFP SURVEILLANCE 27-Jul-20 Week 30, ending 26 July 2020 Number 1138 Table 3: Investigation of AFP cases with paralysis onset in 2019 & 2020 up to Week (30/20) / Ending on : 26/07/2020) 2019 2020 Wild Wild cases AFP Specimen AFP Specimen cases **** **** Case classification Case classification ** COUNTRY ** * * adequate adequate *** *** rate VDPV VDPV Cases specimens Cases specimens Latest onset of onsetparalysis of onsetparalysis of Wild P1Wild Poliovirus P3Wild Poliovirus P1Wild Poliovirus P3Wild Poliovirus AFP AFP cases pending AFP cases pending AFP cases pending AFP cases pending % with % with Polio Compatible Polio Compatible Non polio AFP Non rate line List Total PolioConfirmed Total PolioConfirmed Pending Classification Pending Classification classification and lab 90 > classification and lab 90 > Annualized polio Non AFP Total AFP cases onset 2019 Total AFP cases onset 2020 days from onsetparalysis of days from onsetparalysis of classification 90 > days from classification 90 > days from Discarded polio AFP) (non Discarded polio AFP) (non Date Afghanistan 3768 29 1 0 3738 0 18.1 0 0 94.1 29 0 1922 34 0 324 1535 30 15.7 30 2 94.6 34 0 26/07/2020 Bahrain 17 0 0 0 17 0 5.9 0 0 100.0 0 0 10 0 0 6 4 0 6.1 3 3 90.0 0 0 26/07/2020 Djibouti 5 0 0 0 5 0 1.4 0 0 80.0 0 0 0 0 0 0 0 0 0.0 0
