On Feb 1, 2002, inactivated poliomyelitis vaccines replaced live-attenuated oral poliovirus vaccine (OPV) in New Zealand's immunisation schedule, allowing systematic monitoring of OPV virus circulation. Findings of paediatric-inpatient surveillance indicate that 7% of children excreted polioviruses before this switch, but none did so 1 month afterwards. Acute flaccid paralysis surveillance detected no poliovirus during and after the switch, whereas enterovirus surveillance detected poliovirus only once during the switch. Environmental surveillance identified polioviruses in sewage samples until May, 2002, after which they were detected infrequently. Intratypic differentiation and sequencing showed that all polioviruses were Sabin-like. Multiple surveillance methods hence showed that OPV strains did not persist for extended periods after a vaccine switch in a developed country with a temperate climate. Sequence homology with Sabin vaccine parent strains indicated that polioviruses detected more than 4 months after the switch were of recent origin, consistent with importation from OPV-using countries.

IN THE PAST TWO YEARS ALONE, SHE'S BEEN THE subject of a Lifetime television special starring Shirley MacLaine and of two motion pictures featuring Audrey Tautou and Anna Mouglalis. Now, Coco Chanel is in the spotlight yet again, this time as the topic of a new biography, \"Coco Chanel: The Legend and the Life,\" out from Collins.

While the overall success of fashion week at Lincoln Center remains to be seen, one thing's for sure: attendees won't be going hungry. Here, WWD presents some of the best offerings from the myriad eateries surrounding the Upper West Side venue. There's something for every palette and mental state — from the carb-craving editor nursing a hangover to the pescatarian intern who just got chewed out by her supervisor. Those

Whether in Paris, London or New York, the nightlife scene is crawling with Euros: Tatiana Santo Domingo, Stavros Niarchos, Olympia Scarry...But who are they? How do they all know each other? And, more to the point, why do we all care? Here, WWD has fashioned a handy chart identifying members of the pedigreed pack and their ties to one another. Turns out, it's one Gordian knot: one set of siblings dating another set of siblings (Charlotte Casiraghi, Alex Dellal; Pierre Casiraghi, Alice Dellal); cousins romancing cousins (Lapo Elkann, Bianca Brandolini D'Adda), and none other than Mary-Kate Olsen and Paris Hilton deeply entrenched in the fray.

On the surface, Rufus Wainwright and Kylie Minogue may seem like an odd on-stage pairing. But the singers, who will perform at Saturday's annual Watermill Center concert, are a lot more alike than one would think. Here, a side-by-side comparison.

GIVEN HER PAINTINGS' PSYCHEDELIC PATTERNS and far-out color palettes, artist Melinda Hackett seems more like the product of a Haight-Ashbury commune than a white-glove Park Avenue address. Talk to Hackett about her work and this notion is furthered.

THE NAME DAVID LACHAPELLE MAY BE SYNONYMOUS WITH CELEBRITY portraiture (he's shot everyone from Lady Gaga to Hillary Rodham Clinton during his 30-year career), but, as the 47-year-old photographer proudly notes, his surname, French for \"the chapel,\" is Huguenot in origin. \"It's literally in my blood to question the church,\" he says.
