Epidemiologic situation (1)
  • As of 31 May 2005 a total of 461 AFP cases were
    reported
  • The distribution by governorate is shown in
    (Tables 1 4)
  • Out of the 250 AFP cases where the lab testing
    was finalized, 179 were wild poliovirus type 1
    positive and 71 negative
  • These 179 positive cases are from (Table 5)
  • Alhudaidah (133)
  • Sanaa City (4)
  • Hadramoat Almukalla (2) and Hadramoat Sayeun (12)
  • Hajjah (7)
  • Taiz (8)
  • Amran (8)
  • Rimah (2)
  • AlDhale (1)
  • AlBaidah (1)
  • Abyan (1)
  • Isolates from 15 cases are pending ITD Hudaidah
    (8), Hadramoat Sayeun (3), Hajjah (1), Dhamar
    (2), Albaida (1).

Epidemiologic situation (2)
  • In Hudaidah governorate Laboratory confirmed
    polio cases were reported from 20 districts.
    Most of these cases were infected before the
    April NID campaign (Table 2)
  • So far the spread in the other 10 governorates is
    of lesser extent, possibly due to the effect of
    the NID (Table 4)
  • There is evidence of a decrease in number of
    reported AFP cases after week 17 ending 24 April
    (10 days after the first day of the NID), (Figure
    1)
  • More than half the polio cases are less than 2
    years and another 22 is 2-3 years old, those
    above 5 are only 7 (Figure 2)
  • Investigation of cases showed many of them come
    from areas which were not covered during April
    NID round, which had coverage figures below
    expectation. The number of OPV doses received by
    about 70 of the cases was less than 4 doses
    (Figure 3)

Important Recent Activities
  • The 2nd round of National Immunization campaign
    started on 30th of May after excellent
    preparations.
  • Technical support for campaign planning was
    provided by 5 experts recruited by WHO.
  • Microplans were developed, training of
    vaccinators and supervisors completed.
  • The Campaign was inaugurated by H. E. the Prime
    Minister of Yemen with wide presence of higher
    officials (MOPHP), Mayor of Sanaa City, Head of
    Red Crescent, WHO Representative Staff.
  • Launching was done in most governorates by
    different governers.
  • Preliminary feedback from the field is good.
