Duniya ke mukhtalif mumalik mein mausam sarma ka aghaaz hone wala hai, aise mein nazla, zukam aur sans ki bimariyan aam hongi. Darhaqeeqat, Bahrul-Kaahil (Oceania) mumalik ke adad o shumar batatay hain ke flu ki leher 2022-2023 mein khaas tor par jarrasana ho sakti hai.
Is peshgoi mein humein yeh bhi madde nazar rakhna chahiye ke yeh mumkin tor par COVID ki ek nai lehr bhi saath la sakti hai jo COVID ki mojooda aqsaam se zyada mo’asar aur taqatwar ho gi.
Isi liye Aalami Idara Sehat (WHO) ne pehle hi khabardar kiya hai ke Europe mein iqdamat kiye jayein aur sehat ki bunyadi sahoolat ko mabsoot kiya jaye kyun ke humein iski zarurat par sakti hai.
COVID mein sans lene mein mushkil ki alamat ke ilawa (jis mein nazla se jaan lewa pneumonia tak shamil ho sakta hai) humein ek aur tashweeshnaak haqeeqat par tawajjo dene ki zarurat hai aur woh hai SARS-CoV-2 (COVID) aur doosray sans ke virus dil ke amraz ki wajah ban sakte hain.
Darhaqeeqat doosri wabai amraz se honay wali tabahi ke baad hamare paas jo ilm hai usse zahir hota hai ke yeh alamat zindagi ki mutawaqqa umar ko mutasir kar sakti hain aur qabl az waqt maut ka sabab ban sakti hain.
Sanah 1918 mein flu ki a’alami wabaa ke baad us waqt ki saayinsi tehqiqat mein dimaagi dhund aur shadeed thakaawat ki alamat ko bayan kiya gaya, jo aaj bhi COVID-19 ki wabaa se wabasta do alamat hain.
Lekin flu ki aam alamat ke ilawa sanah 1918 ki flu ki wabaa ke baadzan samnay aane wale asraat ne ek bohat hi pareshan kun nateejah chhoda tha jis mein is se mutasir afraad mein dil ke doray ki ek lehr thi, jis ne 1940 aur 1959 ke darmiyan duniya ko hila kar rakh diya tha.
Flu wabaa se mutasir afraad mein dil ke doray ki yeh lehr bohat ajeeb aur bazahir naqaabil-e-bayan thi magar aaj hum jaante hain ke iska talluq guzashta flu ki wabaa se tha. Is flu wabaa ke virus ne chand mutasirien mein dil ke pohyda aariyazay ki soorat mein ek time bomb chhod diya tha.
Dil ki bimariyon ki is lehr ne khaas tor par mardon ko mutasir kiya, bilkul usi tarah jaise flu ki wabaa ne aur ab haal hi mein COVID-19 ki wabaa ne mutasir kiya. Iski ek mumkin wazehaat yeh di gayi ke sanah 1918 mein wabaa se zinda bach jane wale 20 se 40 saal ki umar ke mardon mein ghair mamooli madafati rad-e-amal ki wajah se unhein qabl az waqt amwatein ka khatra barh gaya.
Lekin is se bhi barh kar yeh ke sanah 1918 mein jin afrad ko flu ki wabaa ne mutasir kiya tha ab unmein 60 ki umar mein dil ke aariyazay ke imkanaanat bohat zyada thay.
Baad azan is par hone wali tehqiqat mein yeh baat samnay aayi ke influenza virus ke infection ke bais atherosclerosis ke (dil ki aik bimari jis mein aik ghair lachikdaar maada dil aur uski shiraayon par jama ho jata hai) imkanaanat bohat zyada barh jate thay aur dil ke doray ka khatra rehta tha. Is se dil ki shiraayon ki andarooni jhilli ko tezi se nuqsan pohanchne ki wajah se wahan khoon jamta aur dil ke doray ka khatra hota.
COVID aur dil ke amraz:
In alamat ki wazahat ke liye, do imkaanat par ghour kiya jata hai aur dono hi mustahkam shawaid par mabni hain:
Pehla yeh ke viral infection ke khilaf aik insaan ka ghair mutawazan madafati rad-e-amal jism mein aik soozish ke amal ka sabab banta hai jo dil ki shiraayon ko nuqsan pohanchata hai.
Jism ke aza mein soozish jis ka zyada se zyada asar cytokine toofan hai, dil ki shiraayon ki bimari ya shiraayon mein soozish ka sabab banta hai. Lehaza aise COVID se mutasir hone wale aise afrad jin mein pehle hi dil ke aariyazay ki shikayat thi yeh soozish unki takleef mazeed barhadi hai.
COVID virus ACE2 protein ka istemal karte hue khaliya mein daakhil hota hai jo insani jism mein khoon ki naliyon mein endothelial khuleon mein kasrat se paayi jaati hai.
Yeh protein insani jism mein dil ke nizam ko kaam karne, fashaaar khoon ko qaim rakhne, insani khuleon mein barqi lehr banane, khoon ki naliyon ko sehatmand rakhne aur soozish ke liye nihayat ahm hai.
COVID-19 se mutasir khawateen mein barhtay isqat-e-haml:
Jaisa ke COVID virus endothelim ko mutasir karta hai to yeh bohat mumkin hai ke yeh placenta (jo hamal ke teesre maah mein zahir hoti hai aur reham ki andarooni deewar ke sath milhak hoti hai) samet dil ke intehai ahm tissues ko na-qabil-e-talaafi nuqsan pohanchaye.
Yeh baat iski wazahat karti hai ke woh khawateen jo COVID se mutasir hui un mein isqat-e-haml ki sharah zyada hai. Darhaqeeqat, COVID se mutasir hamilah khawateen mein dil ki shiraayon ko pohanchne wala nuqsan, bilkul waisa tha jaisa un hamilah khawateen mein tha jinhein intehai buland fashaaar khoon ke marz preeclampsia ka masla tha. Yeh hamilah khawateen mein aik intehai buland fashaaar khoon ka marz hai jis se dil ki shiraayon ko nuqsan pohanchta hai aur is se unka hamal gir jata hai.
Is ke ilawa, doosri tahqiqat se pata chalta hai ke ibtidaai hamal mein virus janin ke azaa ko nuqsan pohanchaa sakta hai jo soozish ke amal se munsalik hota hai.
Vaccine aur myocarditis ke marz mein talluq ke koi shawaid nahi.
Protein S ke endothelim par asar ka talluq mRNA se tayar kardah vaccine ki wajah se mumkinہ dil ki shiraayon ke nuqsan se joda gaya hai. COVID vaccines is protein ko tissues mein paida karti hain taake madafiati nizam isay pehchaan le aur is ke khilaf mutaharik ho jaye. Lekin is se nuqsan ka andaza nahi lagaya ja sakta.
Haal hi mein shaya ek tahqiqat mein 192.5 million afrad ko America mein vaccine lagayi gayi aur un mein se das lakh mein se sirf 8.4 afrad ko dil ki shiraayon ka marz lahiq hua. Aur un mein se bhi sirf 92 afrad ko zyada ilaaj ki zarurat pari aur un mein se kisi ki bhi halakat nahi hui.
Lihaza is tarah ka khauf phailane ki zarurat nahi hai. Vaccine lagne ke baad un afrad mein dil ki shiraayon ki maslay ki nishandahi ki gayi jo ibtida mein mamooli thi. Un afrad mein qudrati madafiati nizam ke taht zyada soozish ke amal ko zahir kiya lekin yeh barah-e-rasht protein S ki wajah se nuqsan nahi tha.
Darasal, vaccination ke baad khoon mein protein S ki satah bohat kam ho jati hai aur endothelim par iska asar aariyi hota hai, jo chand dinon mein ghaib ho jata hai.
Dil ki shiraayon ko nuqsan pohanchne se bachana:
Khush qismati se, vaccination in asraat ke saath saath COVID-19 ke khilaf bhi mo'asar sabit hui hai. Iski saada si daleel hai ke agar virus khoon tak nahi pohanch sakta to yeh dil ke nizam ko mutasir nahi kar sakta.
Lihaza, corona se bachao ki vaccine lagwanay ki ek aur badi wajah yeh hai ke yeh virus humein mutasir na karein aur vaccine saalon baad bhi zindagiyan bachaa sakti hai.
