  • Analysis
    • The continuing detection and investigation of suspected and laboratory positive cases demonstrate that active surveillance is functioning well in some areas.
    • Nevertheless, it is important to note the inherent difficulties in surveillance and laboratory confirmation capacities.
    • It remains possible that detection of a case could be delayed in some remote areas.
    • A strong and sustained surveillance effort is therefore more crucial than ever.
