Mu gihe c’ugukomeza gukura kw’isoko ry’ubwiza kw’isi yose, amacupa y’ibirahuri, nk’imwe mu bikoresho nyamukuru vy’ibikoresho vy’ubuhinga bwa none, vyacitse ikintu nyamukuru amashirahamwe y’ubudandaji yo mu mahanga mu bijanye n’ugutuma ibintu bigenda neza. Ubwo bwoko bw’igicuruzwa bufise ubugoyagoye n’agaciro kanini, ivyo bikaba bishira ibisabwa bidasanzwe ku bijanye n’ingene umuntu ashobora gutwara abantu.
Uvuye mu buryo bw’umubiri, ubugoyagoye bw’amacupa y’ibirahuri ni ingorane nyamukuru mu bijanye n’ivy’ubuhinga. Uburemere bw’icupa akenshi buri hagati ya 1,5-3 mm, kandi ubushobozi bwo guhangana n’ingaruka buragoyagoya, cane cane mu gihe c’ugutwara abantu ku rugero rurerure, ivyo bishobora kwononekara n’ibipfunsi n’ugucapura. Amakuru yerekana ko igipimo c’uguca ibirahuri ari nk’ibice 0,5%-2%, hejuru cane kuruta 0,1% vy’ibintu vy’amapulasitike. Kubera iyo mpamvu, amashirahamwe y’abahinga mu vy’ubuhinga bwa none muri rusangi afata imiti y’ibipapuro vy’ibintu vyinshi, nk’ugushiramwo ifu ya EPE canke film y’ibibumbano hagati y’amacupa, no kwongerako ibice vy’impapuro mu gasandugu k’inyuma kugira ngo yongere inkomezi z’ugukomera n’ibice birenga 40%.
Ku bijanye no guhitamwo uburyo bwo gutwara, amacupa y’ibirahuri ararushiriza gutahura amahinduka mu bushuhe no mu bukonje. Naho ugutwara ikiyaga kiri hasi-ffice, umuntu akwiye kwitwararikwa ku bijanye n’uguhumanya n’ubukonje-Kutanga mu gitereko kugira ngo ntihagire ikintu co gukurako icupa. Naho gutwara umuyaga ari igihe- uburyo bwo hejuru, uburebure bw’ikirere n’uburebure buke bw’ibirahuri bishobora kwongera ubugoyagoye bw’ibirahuri, kandi bukeneye gukoreshwa n’ibikoresho vy’ubushuhe buhoraho. Mu myaka iheze, gutwara abantu n’ibintu vyacitse uburyo bushasha kubera ukuntu Ubushinwa buzwi cane. Incuro yayo y’ugunyiganyiga ni hasi y’iyo gutwara inzira, kandi amasandugu y’ibiti ashobora kugabanya neza ingorane zo kumena.
Dufatiye ku bijanye n’ugukurikiza ubudandaji mpuzamakungu, ibintu vy’ibirahuri bitegerezwa kwubahiriza amabwirizwa yo gupfunyika mu gihugu aja. Ishirahamwe ry'Ubumwe bw'Uburayi risaba ko ibikoresho vy'ibirahuri bitegerezwa guca mu kigeragezo c'itonde (uburebure bwa metero 1,2), kandi FDA ya Amerika ivuga ko ibimenyetso bitegerezwa kwihanganira uguhinduka kw'ubushuhe kuva kuri -20 kugeza ku 60℃. Ibihugu bimwebimwe kandi birafise amategeko yihariye ku bijanye no gusubira gukoresha no kuvura imyanda y’ibirahuri, n’amashirahamwe yoherezwa hanze arakeneye gutahura amategeko agenga ibidukikije y’isoko ry’intumbero imbere y’igihe.
Kubera ko umusaraba uzamuka- Nya-ngwa, ugusaba kw'ibice bitobito - n'ivy'agaciro kanini- Gutwara amacupa y'ibirahuri vyaraduze cane. Iryo shirahamwe ririko rirondera amasandugu y’ivyuma bishobora gusubira gukoreshwa kugira ngo bisubirire amakarito ya kera. Uwo muti ushobora kugabanya igiciro c’ugutwara rimwe gusa n’ibice 15% kandi bikagabanya imyanda yo gupfunyika n’ibice 30%. Mu gihe kizoza, uguhuza uburyo bwo gukurikirana ibikoresho vy’ubuhinga n’ibikoresho vy’ubuhinga bwa none bizokwongereza ubushobozi bwo gukoresha neza uruhererekane rw’ibikoresho vy’ubuhinga bw’ibirahuri.
