Chinyorwa chikuru chePandemic

Shoko rekuti **Pandemic** rakabva parurimi rwechiGreek ishoko rinoreva kupararira kwechirwere chinopomeranwa icho chinenge chafamba kana kushanyira matunhu kana nyika dzakawanda kudarika imwe chete. Kupararira nekukasira kwechirwere muvanhu vazhinji vagere munzvimbo imwe kana dunhu rimwe nemnguva pfupi kunodaidzwa nezita rechirungu rekuti epidemic. Chirwere chakapararira asi huwandu hwevanhu vachakabata huchiramba hwakadzikama chinonzi **endemic**, kwete pandemic. Chirwere chikava endemic asi chiine huwandu hwakadzikama hwevanhu vachakabata , zvakafanana nedzihwa rinopota richinyuka zvichienderana nemwaka chiri kunze kweboka iri nokuti zvinoitika panguva imwechete mumatunhu mahombe dzepasirose kwete kupararira nenyika yose.

## Tsanangudzo nematanho
Zita rekuti pandemci rinoshandiswa kutsanangura epidemic iri kuitika ichigura miganhu yenyika.  Chirwere kana chimiro chero chikapararira kwakawanda kana kuuraya vanhu vakawanda hachizodaidzwi kuti pandemic nokuda kwaizvozvo zvoga, chinofanirawo kuva chinotapuriranwa. Semuenzaniso, chirwere chegomarara chinokonzera kufa kwevanhu vazhinji asi hachiverengwi sepandemic nekuti hachitapuriki kana kuparadzirwa.

Kupararira kwema epidhemic (nemapandemic) kana kuchitaridzwa pagraph kunobudisa chimiro kana kuti dendenedzu rakaita sebhera, chichitaridza huwandu hwevanhu vanenge vabatwa nechirwere panguva imwe neimwe. Dendenedzu iri kazhinji rinongobuda rakadaro kana chirwere chapararira. Zvirwere zvinotapuriranwa kazhinji zvinopararira muzvikamu zvitatu sezvakataridzwa pagraph rinotevera.

**Chikamu chekutanga** chinowanikwa panotanga dendenedzu. Kana tikatora chirwere chapararira cheCOVID-19 semuenzaniso, ndizvo zvinotaridza panotangira kupararira kwechirwere, panenge panevanhu vashoma vanenge vachizivikanwa kuti vakabatwa nechirwere chacho.

**Chikamu chechipiri** chedendenedzu reepidemic chinotaridza nhanho inodaidzwa nezita rechirungu rekuti "community phase"  Panhanho iyi ndipo panobuda hochekoche yekubatwa kwevanhu nechirwere apo vanhu vanga vasina chirwere ichi vanotangawo kubatwa nacho.

**Chikamu chechitatu** chedendendzu reepidemic chinotaridza kuti kupararira kwechirwere kwadzorwa, kana kuti hazvichakwanisiki kuti kuwanikwe vamwe vanhu vatsva vanobatwa nacho.

## Kudzora kupararira kwechirwere
Kune matanho akawanda anogona kutorwa nenyika kudzora kunyuka kwepandemic. Mugore ra2005, sangano reWorld Health Organisation rakakumikidza gwaro rinodaidzwa nechirungu kuti International Health Regulations, rinova iro gwaro remutemo rekudzivirira, kudzora pamwe nekumirisana nezvimiro zvehutano zvinogona kutapuriranwa pakati penyika dzakasiyana.  Pamusoro pazvo sangano reWorld Health Organisation rakaumba gwaro rinopa gwara pakurwisana nema pandemic echirwere chedzihwa. Gwaro iri rakatanga kuburitswa mugore ra1999 rikazodzokorodzwa nekuvandudzwa mugore ra2005 nemuna 2009. Matanho mazhinji ekudzivirira chirwere cheCOVID-19 akatorwa kubva mugwaro reInternational Health Regulations 2005 nemuzviga zveWorld Health Organisation zvekugadzirirwa kwekumirirsana nemapandemic edzihwa.

Pava nenhaurirano dzakawanda pamusoro penzira yekurwisa inodaidzwa kuti 3T's (Testing, Treatment, Tracing) zvichireva (kuvheneka, kurapa, kuteverera) iyo inoita kuti nyika dzikwanise kuona nekukasira uwandu hwevanhu vakabatwa nechirwere dzisati dzavapatsanura kubva kune vamwe vanhu pamwe nekuvarapa. Nzira yacho inosanganisira kuteverera vanhu vese vakambosangana nemunhu anechirwere wacho, kwava kuvapatsanurawo nevamwe. Nzira iyi yaita mukurumbira nekuda kwekubudirira kwayakaita munzvimbo dzinoti South Korea neSingapore, kunyangwe hazvo zvichifungidzirwa kuti nyika mbiri idzi dzakagara dzakagadzirira mushure medambudziko rakakonzerwa nechirwere cheSARS.

Kumira vanhu vakaparadzana, kana kuti kusiya nzvimbo pakati pako nevamwe vanhu, idanho rezvehutano hweveruzhinji rakanangana nekunonotsa kupararira kwechirwere kuburikidza nekukonesa vanhu kusvika pedyo napedyo kuitira kushaisa mukana kutapuriranwa kwezvirwere zvinopararira nezvinotapuriranwa. Mukuru mukuru wesangano reWorld Health Organisation, Chiremba Michael J Ryan vachitaura nevatapi venhau muna Kurume 2019 vakati ivo kumira wakasiya nzvimbo pakati pako nevamwe vanhu "idanho rinoshanda kwenguva pfupi rekudzora kumhanya kwekupararira kwechirwere, nokubvisa mutoro pamapato ezvehutano, asi zvisingapedzi hutachiwana pachahwo. Danho iri rinodhura, huye rinoda kushandiswa pamwe chete nemamwe matanho ekurwisana nedambudziko."  Chiremba Ryan vakajekesa kuti kusiya nzvimbo pakati pako nevamwe vanhu chete hakungagoni kupedza chirwere.

Chinyorwa chikuru: Kupikiswa kwemishonga yerudzi rwemaAntibiotic

Hutachiwana hune simba rekupikisa mushonga wemaAntibiotic hunodaidzwa dzimwe nguva nezita rechirungu rekuti "masuperbugs". Hutawana hwerudzi uhwu hwunokwanisa kubatsira kunyuka zvakare kwezvirwere zvanga zvambokwanisa kudzorwa zvakanaka.  Semuenzaniso, zviitiko zvechirwere cherurindi kana kuti TB zvine simba rekupikis amishonga yagara ichizivikanwa kuti inorapa chirwere ichi zvakanaka idambudziko guru kune vezveutano. Zviitiko zvitsva zvinoda kusvika chidimbu chemiriyoni imwechete zvekupikiswa kwemishonga mizhinji yerurindi, uko kunodaidzwa nechirungu kuti multi-drug resistant tuberculosis (MDR-TB) zvinoitika gore negore.  China ne India ndidzo nyika dzine zviitiko zvakawanda zve dambudziko iri.  Sangano rezveutano hwepasirose reWorld Health Organisation (WHO) rinobudisa mashoko ekuti huwandu hwevanhu vanofungidzirwa kusvika pa mamiriyoni makumi mashanu pasirose vane chirwere cheMDR TB, zvikamu makumi manomwe nezvipfumbamwe kubva muzana zvavo zviri zvevanhu vane chirwere cherudzi rwunopikisana nemishona mitatu kana kupfuura. Mugore ra2015, zviitiko zvinosvika zana nemakumi maviri anezvina zveMDR-TB zvakaonekwa muAmerica (United States) chete. Imwe mhando yechirwere cherurindi inopikisana mishinga yakawanda zvakapamhidzirwa iyo inodaidzwa nechirungu kuti extensively drug-resistant tuberculosis (XDR-TB) yakaonekwa muAfrica mugore ra2016, ikazoonekwa kuti yaiwanikwawo munyika makumi mana nepfumbamwe, kusanganisira muAmerika.
