Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Edwin Klebs akanga ari wokutanga kucherechedza utachiona mumigwagwa yokufema yavanhu vakanga vafa nepneumonia muna 1875. Basa rokutanga rokuziva mabhakitiriya maviri anowanzokonzera zvirwere, Streptococcus pneumoniae naKlebsiella pneumoniae, rakaitwa naCarl Friedländer naAlbert Fraenkel muna 1882 na1884. Basa rokutanga raFriedländer rakaita kuti pave nomuedzo unonzi Gram stain, uyo uchiri kushandiswa mazuva ano pakuongorora mabhakitiriya. Chinyorwa chaChristian Gram chinorondedzera muitiro wacho muna 1884 chakabetsera kusiyanisa utachiona huviri uhwu, uye chakaratidza kuti pneumonia yaigona kukonzerwa nemakemikari anopfuura rimwe chete. Sir William Osler, anozivikanwa sa"baba vomushonga wemazuva ano", akaonga rufu uye kuremara kunokonzerwa nepneumonia, achirondedzera so"mukuru wevarume vorufu" muna 1918, sezvo yakanga yatora chirwere chepfuva sechimwe chezvinhu zvikuru zvinoparira rufu panguva ino. Mashoko aya akatanga kutaurwa naJohn Bunyan achitaura nezve"kushandiswa kwezvinhu" (TB). Osler akarondedzerawo pneumonia se "shamwari yemurume akwegura" sezvo rufu rwaive rwekukurumidza uye rusingarwadzi apo paive nenzira dzinononoka uye dzinorwadza dzekufa. Zviitiko zvakati wandei muma1900 zvakavandudza mhedzisiro kune avo vane pneumonia. Nokuvapo kwepenicillin nemimwe mishonga inorwisa mabhakitiriya, unyanzvi hwokuvhiya hwemazuva ano, uye kurapwa kwakasimba muzana remakore rechi20, nhamba yevanhu vaifa nepneumonia, iyo yakanga yava kusvika pa30%, yakaderera zvikuru munyika dzakabudirira. Kubayiwa nhomba kwevacheche kurwisa Haemophilus influenzae rudzi B kwakatanga muna 1988 uye kwakatungamirira kukuderera kukuru muzviitiko nokukurumidza pashure pacho. Kubayiwa nhomba yeStreptococcus pneumoniae kuvanhu vakuru kwakatanga muna 1977, uye kuvana muna 2000, zvichiita kuti kudererawo kwakadaro kuitike.  Mubvunzo: Ndiani akagadzira nzira yokuongorora nayo mabhakitiriya?
