Wetin na Herd Immunity?
Fɔ tɔk am simpul wan, herd immunity na we bɔku pan di pipul dɛn we de na wan patikyula eria dɔn gɛt imyuniti, dat na, protɛkshɔn, agens wan patikyula sik.
Tink bɔt am dis we. Bɔku pan di pipul dɛn na wi vilej nɔ gɛt mizɛl. So ivin if pɔsin we kɔmɔt na do kam na di vilej wit mizɛl, di chans fɔ mek dɛn spre di sik to ɔda pipul dɛn kin rili smɔl. Wetin du? Bikɔs bɔrku pan de pipul dɛm wae de arawnd dɛm nɔr kin gɛt dis sik. I tan lɛk se di vayrɔs we de mek di sik nɔ gɛt we fɔ rich de. Afta sɔm tɛm, di vayrɔs nɔ gɛt say fɔ skata, so di sik kin dɔn smɔl smɔl na di kɔmyuniti.
Di big bɛnifit fɔ dis na dat pan ɔl we dɛn de protɛkt di wan ol sosayti dis we, di grup dɛn we nɔ gɛt bɛtɛ wɛlbɔdi we nɔ ebul fɔ gɛt imuniti fɔ sɔm rizin dɛnsɛf kin gɛt protɛkshɔn ɔtomɛtik wan.
fכ egzampl, dis de gi big protεkshכn fכ pipul dεm lεk yכng pikin dεm, pipul dεm we wik imyun sistεm (e.g., kεnsar pasεnshכn, pipul dεm we de gεt כgan transplant), εn pipul dεm we nכ kin gεt vaksin biכs di chans fכ di sik kam to dεm dכn dכn.
Aw wi de mek dis herd immunity?
Tu men we de we dis herd immunity kin apin.
1. Natura l Infεkshכn
We pɔsin gɛt vayrɔs ɔ baktri, wi bɔdi in imyun sistɛm kin bigin fɔ fɛt am. Fɔ fɛt dis, wi bɔdi kin mek sɔntin we dɛn kɔl antibodies . Afta di sik dɔn wɛl, dɛn antibodi ya kin stil de na wi bɔdi. If di sem jem we mek di sik kam bak na wi bɔdi wan de, wi bɔdi kin yuz dɛn antibodi dɛn de fɔ win am. Dis na aw dɛn bin kɔntrol di Zika vayrɔs we bin de bɔku na Brazil. Insay tu ia, 63% pan di pipul dɛm we bin de de bin dɔn gɛt di vayrɔs, we dɔn mek dɛn gɛt di herd immunity, di risach pipul dɛm biliv.
2. Tru vaksin
Vaksin na di we we sef ɛn we go wok fayn fɔ bil di herd immunity. Wetin vaysin de du na fɔ "trik" wi bɔdi fɔ tink se wi gɛt di sik, we wi nɔ rili gɛt am. Dɔn wi imyun sistɛm de mek di antibodi dɛm we wi bin dɔn tɔk bɔt. So if di jem we rili kɔz di sik ɛva kam insay wi bɔdi, wi bɔdi dɔn rɛdi fɔ fɛt am. Dɛn bin dɔn pul polio kɔmɔt na kɔntri dɛn lɛk Amɛrika bikɔs ɔf di herd immunity we vaksin bin mek.
Herd Immuniti Threshold ɛn R0 Valyu
Nɔto ɔl sik kin nid di sem nɔmba fɔ pipul dɛn fɔ gɛt di herd immunity. I dipen pan aw di sik kin skata kwik kwik wan. Wan we fɔ mɛzhɔ dis spid na in dɛn kɔl R0 (R-naught) .
R0 de tɔk bɔt di avɛrej nɔmba fɔ pipul dɛn we pɔsin we gɛt di sik kin gɛt na sosayti we nɔ gɛt ɛni imyuniti. Fɔ mek di R0 valyu go ɔp, ɛn fɔ mek di herd imuniti apin, di pasɛnt pipul dɛn we gɛt imuniti na di sosayti fɔ inkrisayz bak bad bad wan.
Luk di tebul we de dɔŋ ya, ɛn dis go klia to yu.
