St\u00f8v er en stor rejsende. Det er ikke ualmindeligt, at et tyndt lag st\u00f8v fra Sahar\u00f8rkenen i Afrika l\u00e6gger sig p\u00e5 parkerede biler tusinder af kilometer v\u00e6k.<\/p>\n<\/div>\n

Men st\u00f8v kan v\u00e6re livsfarligt. I de t\u00f8rre udkantsomr\u00e5der af Sahara (kendt som Sahel) er 300 millioner mennesker udsat for en d\u00f8delig sygdom kaldet meningitis.<\/p>\n

Denne sygdom for\u00e5rsager h\u00e6velse af hjernen og rygmarvshinden. De, der overlever, kan blive ramt af h\u00f8retab og hjerneskade.<\/p>\n

\u201cDer opst\u00e5r udbrud af meningitis efter en periode uden regn, med lav luftfugtighed og meget st\u00f8v i luften,\u201d forklarede Isabelle Jeanne fra Centre de Recherche M\u00e9dicale et Sanitaire i Niger.<\/p>\n

Den n\u00f8jagtige sammenh\u00e6ng er endnu ikke kendt. En teori g\u00e5r ud p\u00e5, at vindb\u00e5ret st\u00f8v, der er lige s\u00e5 fint som talkum, for\u00e5rsager irritation i n\u00e6sen. Dette g\u00f8r det lettere for bakterier at tr\u00e6nge ind i blodbanen.<\/p>\n

ESA hj\u00e6lper forskere med at unders\u00f8ge og forudsige udbrud af meningitis. M\u00e5let er at f\u00e5 mere viden om de d\u00f8delige epidemier, der ofte f\u00f8lger i k\u00f8lvandet p\u00e5 st\u00f8vets ankomst.<\/p>\n

Medicinske forskere bruger satellitbilleder til at f\u00f8lge de enorme st\u00f8vstorme, der fejer hen over Sahel. I l\u00f8bet af den seneste t\u00f8rkeperiode leverede ESA ugentlige st\u00f8vkort som led i et tidligt varslingssystem. Kortene over Sahel er baseret p\u00e5 daglige billeder fra vejrsatellitten Meteosat-7, der er bygget af ESA.<\/p>\n

Det n\u00e6ste skridt er at unders\u00f8ge billeder taget i l\u00f8bet af de seneste 10 \u00e5r og lede efter sammenh\u00e6nge mellem st\u00f8vstorme og udbrud af sygdommen.<\/p>","protected":false},"excerpt":{"rendered":"
