Abahanga mu bya siyansi bize ibice ibihumbi 69 bya skeletone zitandukanye
Itsinda ry'impuguke zasesenguye ibimenyetso by'indwara bisigaye ku magufa y'umuntu, byatumye bishoboka gukurikirana inzira y'ubwihindurize kugira ngo irwanye na patogene. Ibisubizo byubushakashatsi bunini bwagaragaye mukinyamakuru kimwe.
Ibintu nyamukuru byakazi bya siyansi byari ibibembe, igituntu na treponematis. Iheruka ni itsinda ryindwara zirimo sifilis. Ikiranga izo ndwara nubushobozi bwabo bwo kugenda ubwayo inzira kumagufwa namenyo. Ibi byemereye impuguke gukurikirana imbaraga zo guteza imbere indwara zigera ku 200. Nkuko Matsa Henneberg, akaba ari akantu kava muri kaminuza ya Flinders muri Ositaraliya, ubwinshi bw'izo ndwara buragabanuka nkuko bahuye no kumenyera. Inzira nkiyi igira uruhare mu gusohoza virusi numuntu ninde utwara.
Mu myaka 5000 ishize, mbere yo kugaragara mumiti igezweho, ibimenyetso bya Skeletal byigituntu byaturutse kandi bike; Kugaragaza ibibembe byo mu Burayi byatangiye kugabanuka nyuma yimyaka yo hagati; Kandi ibimenyetso bya skeletale bya TEPONEMASIS muri Amerika ya Ruguru byagabanutse mumyaka yashize kugirango duhuze nabanyaburayi bateye.Mu rwego rw'umurimo wa siyansi, ibyavuye mu bushakashatsi bwa mbere bw'indwara byize byakoreshejwe, aho abahanga basesenguye skeleti 69,379. Ibisigazwa by'abantu byari ibya mopo zitandukanye, guhera guhera 7250 mbere. e. Kandi irangirana na skeleti yabantu mugihe cacu. Birakwiye ko tumenya ko ibisigazwa byose bitangwa kwandura indwara eshatu, ariko ingano nini yicyitegererezo yemereye inzobere kugirango zifate imyanzuro myinshi kuri siyanse.
Byasanze ko nta ndwara eshatu zahitanye umuntu ako kanya. Ibi byemereye virusi kubaho no gukwirakwira. Ariko, kugabana imibare mugihe cyo kuba ubwiza bwibituntu, ibibembe na Treponemasis bitanga impamvu kugirango abantu bateze imbere kurwanya inyangamugayo, cyangwa indwara ubwazo zabaye mubi.
Ukurikije uko ihindagurika ryuzuye, kuri pathogen byumvikana gutera nyira nyirayo, aho kubaho kwayo biterwa nigihe cyo kwihindurwa gitera igihe - Tegan Lucas, antropropologue kuva Kaminuza ya Flinders, hamwe na we-Umwanditsi w'ubushakashatsi.Abahanga bavuze ko kwasesengura ubwihindurize bw'umubiri na virusi, birakenewe kuzirikana ibintu byinshi bitandukanye bishobora kugira ingaruka ku ikwirakwizwa ry'indwara. Nubwo ubushakashatsi bushya atari menaanalllogiya ikomeye, ibisubizo byayo bizashobora gufasha abahanga mugihe kizaza kugirango umenye impamvu za virusi nshya.
