Cov Kev Kuaj Mob Rau Kab Mob Dengue
Pendahuluuan
Kab mob Dengue hemorrhagic fever (DHF) yog ib yam kab mob kis tau los ntawm kev tom ntawm cov yoov Aedes aegypti thiab Aedes albopictus. Cov kab mob dengue uas ua rau DHF muaj plaub hom kab mob: DENV-1, DENV-2, DENV-3, thiab DENV-4. Kab mob no yog ib qho teeb meem loj rau kev noj qab haus huv hauv ntau lub tebchaws sov thiab sov so, suav nrog Indonesia. Yog li ntawd, cov txheej txheem kuaj mob sai thiab raug yog qhov tseem ceeb rau kev txheeb xyuas thiab tswj hwm tus kab mob no. Tsab xov xwm no yuav tshuaj xyuas ntau txoj kev kuaj mob uas siv los kuaj mob dengue hemorrhagic fever.
Cov tsos mob ntawm tus kab mob Dengue Fever
Ua ntej tham txog cov txheej txheem kuaj mob, nws yog ib qho tseem ceeb kom nkag siab txog cov tsos mob ntawm tus kab mob dengue. Cov tsos mob ntawm tus kab mob dengue feem ntau tshwm sim tom qab lub sijhawm incubation ntawm 4-10 hnub tom qab yoov tshaj cum tom. Cov tsos mob thawj zaug suav nrog kub taub hau sai sai, mob taub hau hnyav, mob tom qab lub qhov muag, mob nqaij thiab pob qij txha, xeev siab, ntuav, thiab pob khaus ntawm daim tawv nqaij. Hauv cov xwm txheej hnyav, tus kab mob tuaj yeem hloov mus ua tus kab mob dengue hemorrhagic fever nrog rau kev los ntshav thiab dengue shock syndrome, uas tuaj yeem ua rau tuag taus.
Cov Kev Tshawb Fawb
1. Kev Kuaj Mob Hauv Tsev Kho Mob
Txoj kev kuaj mob thawj zaug uas feem ntau siv yog kev kuaj mob hauv tsev kho mob. Kev kuaj mob no yog raws li cov tsos mob thiab cov cim qhia ntawm tus kab mob dengue uas tus neeg mob pom. Thaum xub thawj, tus kws kho mob yuav ua keeb kwm thiab kuaj lub cev kom paub cov tsos mob xws li kub taub hau heev, mob pob qij txha, pob khaus, thiab lwm yam tsos mob. Txawm li cas los xij, kev kuaj mob no feem ntau yog raws li tus neeg mob xav tau thiab tsis muaj qhov tshwj xeeb, yuav tsum tau kuaj hauv chaw kuaj mob kom paub tseeb.
2. Kev Ntsuas Ntshav
Rau cov neeg mob uas muaj mob dengue fever, muaj ntau yam kev hloov pauv ntawm cov ntshav. Cov ntshav platelet yog ib qho tseem ceeb tshaj plaws rau kev kuaj ntshav. Thrombocytopenia (cov ntshav platelet tsawg dua) yog ib qho cim qhia ntau rau cov neeg mob uas muaj mob dengue fever. Tsis tas li ntawd, cov ntshav dawb (cov ntshav dawb tsawg dua) thiab cov ntshav ntau ntxiv kuj tseem yuav tshwm sim.
3. Kev Kuaj Mob Ntshav
Kev kuaj ntshav serology yog siv los nrhiav cov tshuaj tua kab mob uas lub cev tsim los teb rau tus kab mob dengue. Ob txoj kev kuaj ntshav serology tseem ceeb yog:
– IgM thiab IgG ELISA: Enzyme-Linked Immunosorbent Assay (ELISA) yog ib txoj kev siv ntau los nrhiav IgM thiab IgG antibodies hauv tus neeg mob cov ntshav. IgM feem ntau tshwm sim 3-5 hnub tom qab pib muaj tsos mob thiab ploj mus li ob peb lub hlis, thaum IgG tshwm sim tom qab thiab tuaj yeem nyob mus ib txhis. Kev kuaj pom IgM qhia tias muaj tus kab mob dengue mob hnyav, thaum IgG qhia tias tus kab mob yav dhau los lossis rov tshwm sim dua.
– Kev Kuaj Mob Sai (RDTs): Cov kev kuaj mob sai no uas siv immunochromatography ua rau nrhiav tau cov tshuaj IgM thiab IgG sai thiab yooj yim. Txawm hais tias tsis tshua muaj kev rhiab heev thiab tshwj xeeb dua li ELISA, RDTs feem ntau siv rau hauv thaj chaw lossis hauv cov chaw uas muaj chaw kuaj mob tsawg.
4. Kev Tshawb Pom Antigen NS1
NS1 (Non-Structural Protein 1) yog ib qho protein uas tus kab mob dengue tsim tawm thaum lub sijhawm kis tus kab mob sai thiab tuaj yeem pom hauv tus neeg mob cov ntshav txij li hnub thawj zaug ntawm cov tsos mob. Kev kuaj pom NS1 antigen siv cov khoom siv kuaj mob ceev NS1 antigen lossis ELISA tuaj yeem muab kev kuaj mob thaum ntxov ua ntej IgM antibodies tshwm sim. Txoj kev no muab qhov zoo ntawm kev kuaj pom thaum ntxov thiab kev tswj hwm sai ntawm cov neeg mob dengue fever.
5. Kev Hloov Pauv Transcription-Polymerase Chain Reaction (RT-PCR)
RT-PCR yog ib txoj kev kuaj mob molecular uas muaj kev nkag siab zoo thiab tshwj xeeb rau kev kuaj cov noob caj noob ces ntawm tus kab mob dengue. Cov txheej txheem no suav nrog kev hloov cov RNA ntawm tus kab mob mus rau hauv cov DNA sib txuas (cDNA) siv cov enzyme reverse transcriptase, tom qab ntawd ua kom cDNA loj dua siv PCR. RT-PCR tuaj yeem kuaj tau tag nrho plaub hom kab mob dengue nrog qhov tseeb siab thiab muab cov ntaub ntawv hais txog cov kab mob hauv tus neeg mob lub cev. Txawm hais tias nws muaj kev nkag siab zoo thiab tshwj xeeb, nws cov kev txwv tseem ceeb yog qhov xav tau cov khoom siv kim thiab cov neeg ua haujlwm txawj, uas tej zaum yuav tsis muaj nyob rau hauv txhua lub chaw kho mob.
6. Cov Txheej Txheem Isothermal Amplification
Cov txheej txheem Isothermal amplification xws li Loop-mediated Isothermal Amplification (LAMP) yog lwm txoj hauv kev rau PCR uas ua tau yam tsis tas yuav siv cov khoom siv hauv chav kuaj mob nyuaj. LAMP yog ib txoj hauv kev DNA amplification uas ua haujlwm ntawm qhov kub tas li, ua rau nws yooj yim dua thiab sai dua PCR. LAMP tau ua pov thawj tias muaj txiaj ntsig zoo hauv kev kuaj pom tus kab mob dengue thiab tuaj yeem siv rau hauv cov chaw uas muaj peev txheej tsawg.
7. Txoj Kev Saib Xyuas (PoC)
Cov khoom siv kuaj mob rau qhov chaw kho mob yog tsim los siv ncaj qha rau ntawm qhov chaw kho mob, muab cov txiaj ntsig sai yam tsis tas yuav tsum muaj chaw kuaj mob. Piv txwv ntawm cov khoom siv PoC suav nrog ntau yam kev kuaj mob sai (RDTs) thiab NS1 antigen kits. Cov khoom siv PoC muaj peev xwm txhim kho qhov ceev ntawm kev kuaj mob thiab kev tswj hwm tus neeg mob, tshwj xeeb tshaj yog nyob rau thaj chaw deb lossis thaum muaj kev sib kis.
Cov Teeb Meem hauv Kev Kuaj Mob Dengue Fever
Txawm hais tias muaj ntau txoj kev kuaj mob sib txawv los xij, tseem muaj teeb meem hauv kev kuaj mob dengue sai, raug, thiab pheej yig. Qee qhov teeb meem no suav nrog:
– Kev Hloov Pauv Hauv Kev Kho Mob: Cov tsos mob ntawm tus kab mob Dengue fever feem ntau zoo ib yam li lwm yam kab mob, tshwj xeeb tshaj yog thaum ntxov. Qhov no ua rau kev kuaj mob nyuaj yog tsis muaj kev pab los ntawm chav kuaj mob.
– Kev Txwv ntawm Chav Kuaj Mob: Hauv ntau thaj chaw muaj kab mob sib kis, cov chaw kuaj mob uas tsim nyog rau kev kuaj mob siab heev xws li RT-PCR tsis tas li muaj. Kev vam khom rau cov txheej txheem ceev thiab pheej yig dua yog qhov tseem ceeb heev.
– Kev rhiab heev thiab qhov tshwj xeeb: Cov kev kuaj mob serological thiab cov khoom siv PoC tej zaum yuav tsis muaj kev rhiab heev thiab qhov tshwj xeeb txaus, tshwj xeeb tshaj yog thaum ntxov ntawm kev kis tus kab mob lossis hauv kev kis tus kab mob thib ob nrog ntau hom kab mob sib txawv.
– Tus nqi: Qee txoj kev kuaj mob, tshwj xeeb tshaj yog cov molecular xws li RT-PCR, xav tau cov peev txheej tseem ceeb ntawm cov khoom siv thiab cov nqi, uas tej zaum yuav tsis ua tau rau txhua qhov chaw.
Cov Lus Qhia Yav Tom Ntej hauv Kev Kuaj Mob Dengue
Kev vam meej hauv kev tawm tsam tus kab mob dengue tsis yog tsuas yog nyob ntawm kev kuaj pom thaum ntxov thiab kev tswj tus neeg mob xwb, tab sis kuj nyob ntawm kev tiv thaiv thiab tswj kev sib kis kab mob. Yog li ntawd, kev tsim cov txheej txheem kuaj mob sai dua, raug dua, pheej yig dua, thiab siv tau dav dua yog qhov tseem ceeb hauv kev tshawb fawb hauv thaj chaw no.
Cov kev qhia yav tom ntej yuav suav nrog kev tsim cov nanotechnology-based biosensors, cov platform kuaj mob sib xyaw ua ke uas muab ntau qhov kev kuaj mob ua ke hauv ib lub cuab yeej, thiab cov thev naus laus zis kuaj mob genomics siab dua los muab cov ntaub ntawv qhia txog tus kab mob thiab cov lus teb ntawm tus neeg mob.
Xaus
Kab mob Dengue hemorrhagic fever yog ib yam kab mob uas xav tau kev kho mob sai thiab tsim nyog. Muaj ntau txoj kev kuaj mob tau tsim los nrhiav kev kis tus kab mob dengue, txhua tus muaj nws qhov zoo thiab qhov tsis zoo. Kev kuaj ntshav serological, kev kuaj NS1 antigen, thiab cov txheej txheem molecular xws li RT-PCR yog qee cov cuab yeej tseem ceeb hauv kev kuaj mob dengue. Cov teeb meem kev kuaj mob tseem muaj, tab sis kev tsim kho tshiab ntawm thev naus laus zis txuas ntxiv txhim kho qhov tseeb, ceev, thiab muaj kev kuaj mob. Kev sib koom tes ntawm cov kws tshawb fawb, cov kws kho mob, thiab cov neeg tsim cai yog qhov tseem ceeb rau kev kuaj mob dengue thiab kev tswj hwm zoo.
