PolioPlus Weekly Update 26 May, 2021
 
 
 
 
 

Greetings Polio Warriors:

  • Wild Polio Virus OK, we can all collectively EXHALE, as I can report to you once again…NO NEW CASES this last week .
 
ONE HUNDRED AND FORTY-FIVE The number of days since the last case of the wild poliovirus Type 1 occurred in Afghanistan.
 
ONE HUNDRED AND NINETEEN The number of days since the last case of         the wildpoliovirus Type 1 occurred in Pakistan.
 
TWO - The total number of cases of the wild poliovirus Type 1 that occurred in the world sinceNew Years Day.
 
FIFTY-NINE - The number of cases of the wild poliovirus Type 1 that occurred in 2020 on this date.
 
Last week marks the SEVENTEENTH WEEK IN A ROW that there has been no reported newcases of the wild poliovirus in either Pakistan or Afghanistan. And on top of that, the THIRD WEEK IN A ROW that there has been ZERO positive environmental samples. We have now pushed the envelope out to three weeks without a case or positive environmental sample of the wildpolio virus. We continue to expand our uncharted territory! Once
againONE, TWO, THREE, DANCE !!!
 
  • Vaccine-Derived Polio - Last week saw an increase in vaccine-derived polio cases: five in DR Congo, three in Madagascar and one each in Burkina Faso, Congo, Guinea and Mali.However, the case in Mali occurred in 2020, but is just being reported now. That brings us to 96 total cases for the year, compared to 122 at this time last year. 6 positive environmental samples of the vaccine-derived poliovirus were also discovered, two in Liberia, two in Tajikistan and oneeach in Pakistan and Madagascar.
 
Novel Oral Poliovaccine - Towards the eradication of the vaccine derived strain of this disease, a May 4th meeting of the Emergency
 
Committee on the international spread of the poliovirus was convened by the WHO Director General. In the meeting statement, available HERE it was verified that the novel Oral Polio Vaccine Type 2 (nOPV2) has been introduced and delivered in two countries (Nigeria and Liberia) with an additional four countries to implement nOPV2 campaigns by the end of May. This is exciting news IMHO, and as reported earlier, sources say we could hopefully have enough data to publish preliminary results sometime next month…stay tuned, as they say.
 
The PolioPlus year end appeal - We are now a little over 4 weeks away from the end of the Rotary year. As mentioned last week, we are lagging     13% behind last year’s figures in our quest to reach the $50 million dollar goal to take advantage of the Gates Foundation 2:1 match. And you already know about DDF donations growing by a factor of 6:1, so I won’t repeat the details here. But…do please consider donating as much DDF as your District can spare to support Rotary’s #1 goal. To donate DDF, TRF recommends using their online system, with the following link: Online DDF Allocation
