Damm f\u00e4rdas l\u00e5ngt. Det \u00e4r inte ovanligt att ett tunt lager damm fr\u00e5n Saharav\u00f6knen i Afrika l\u00e4gger sig p\u00e5 parkerade bilar tusentals kilometer bort.<\/p>\n<\/div>\n

Men damm kan vara livsfarligt. I de torra utkanterna av Sahara (som kallas Sahel) hotas 300 miljoner m\u00e4nniskor av en d\u00f6dlig sjukdom som kallas hj\u00e4rnhinneinflammation.<\/p>\n

Denna sjukdom orsakar svullnad i hj\u00e4rnan och ryggm\u00e4rgens h\u00f6lje. De som inte avlider av sjukdomen kan drabbas av h\u00f6rselneds\u00e4ttning och hj\u00e4rnskador.<\/p>\n

\u201cUtbrott av hj\u00e4rnhinneinflammation intr\u00e4ffar efter en period utan regn, med l\u00e5g luftfuktighet och mycket damm i luften\u201d, f\u00f6rklarade Isabelle Jeanne fr\u00e5n Centre de Recherche M\u00e9dicale et Sanitaire i Niger.<\/p>\n

Damm som bl\u00e5st fr\u00e5n V\u00e4stsahara mot Kanarie\u00f6arna<\/figcaption><\/figure>\n

Det exakta sambandet \u00e4r \u00e4nnu inte k\u00e4nt. En teori \u00e4r att vinddriven damm, som \u00e4r lika fin som talk, orsakar irritation i n\u00e4san. Detta g\u00f6r det l\u00e4ttare f\u00f6r bakterier att ta sig in i blodomloppet.<\/p>\n

ESA hj\u00e4lper forskare att studera och f\u00f6ruts\u00e4ga utbrott av hj\u00e4rnhinneinflammation. M\u00e5let \u00e4r att l\u00e4ra sig mer om de d\u00f6dliga epidemierna som ofta f\u00f6ljer i sp\u00e5ren av dammet.<\/p>\n

Medicinska forskare anv\u00e4nder satellitbilder f\u00f6r att f\u00f6lja de omfattande dammstormar som sveper \u00f6ver Sahel. Under den senaste torrperioden tillhandah\u00f6ll ESA veckovisa dammkartor som en del av ett system f\u00f6r tidig varning. Kartorna \u00f6ver Sahel bygger p\u00e5 dagliga bilder fr\u00e5n v\u00e4dersatelliten Meteosat-7, som byggts av ESA.<\/p>\n

N\u00e4sta steg \u00e4r att analysera bilder som tagits under de senaste tio \u00e5ren och leta efter samband mellan dammstormar och sjukdomsutbrott.<\/p>","protected":false},"excerpt":{"rendered":"
