NB.1.8.1 Covid Variant in India: Kya Yeh Immunity Ko Affect Karta Hai?

NB.1.8.1, ek naya Omicron subvariant, filhaal India aur China mein tezi se spread ho raha hai. Yeh variant pehle ke mukable zyada contagious hai aur immunity ko bypass karne ki ability rakhta hai, chahe aap vaccinated ho ya pahle infected.

NB.1.8.1 Variant Kya Hai?

NB.1.8.1, Omicron ka ek subvariant hai, jo LP.8.1 aur JN.1 jaise variants se closely related hai. Yeh variant pehli baar East Asia (China, Thailand) mein report hua tha aur ab Europe aur India tak pahuch chuka hai.

GISAID global database ke data ke mutabik, is variant ka presence France, Japan, Netherlands, Spain, South Korea, Taiwan aur India ke kai regions mein mil chuka hai.

Kya Yeh Zyada Contagious Hai?

Experts ka kehna hai ki NB.1.8.1 approximately 1.5 times zyada contagious hai pehle ke LP.8.1 variant ke mukable. Ashoka University ke research dean Gautam Menon ke anusar, is variant ke tezi se badhne ka reason abhi tak clearly pata nahi hai, lekin iska spread rapidly ho raha hai.

WHO ne ise ek “variant under monitoring” declare kiya hai, jiska matlab hai ki isme aise genetic changes hain jo virus ke behavior ko change kar sakte hain, lekin abhi tak iska public health impact major nahi hai.

NB.1.8.1 Immunity Ko Kaise Evade Karta Hai?

Ek lab-based study ke mutabik, jo abhi peer-reviewed nahi hui hai, NB.1.8.1 ka ACE2 receptor se binding affinity bahut strong hai. Matlab, yeh variant human cells ko aur efficiently infect kar sakta hai.

Is study ne dikhaya ki vaccine ya previous infection ke baad jo antibodies banti hain, woh NB.1.8.1 ke against 1.5x kam effective hain LP.8.1.1 ke comparison mein. Iska matlab yeh variant immune response ko weak kar deta hai aur easily spread karta hai.

Ab Tak Ke Symptoms Kya Hain?

Filhaal, NB.1.8.1 ke symptoms mostly mild report hue hain. Fever, sore throat, fatigue jaise common Covid symptoms dekhne ko mil rahe hain. Lekin iska immune evasion aur rapid spread concern ka topic zarur hai.

Kya Vaccines Ab Effective Nahi Rahengi?

Experts ka kehna hai ki abhi yeh confirm nahi hai ki JN.1-based vaccines NB.1.8.1 pe kitna kaam karengi. Agar yeh variant widespread hota hai, toh vaccine formulations ko update karna pad sakta hai.

Lara Herrero, jo ek virologist hain Griffith University mein, unka kehna hai ki NB.1.8.1 ke rapid spread ka major reason uska cell infect karne ka better mechanism hai, jisse pehle se existing immunity bhi usse rok nahi pa rahi.

Public Health Ke Liye Kya Matlab Hai?

• NB.1.8.1 ka immune evasion capability isey ek potential risk banata hai.
• Continuous surveillance aur genome tracking zaruri hai.
• Booster shots aur vaccine updates future mein zarurat ban sakti hain.
• Masking, distancing, aur hygiene abhi bhi effective tools hain isse bachne ke liye.

Conclusion: Kya Karein Aap?

NB.1.8.1 ek naya challenge hai, lekin abhi tak severe symptoms ya high hospitalization ka data nahi mila hai. Iske bawajood, caution aur awareness rakhna important hai. Agar aap vaccinated nahi hain, toh turant vaccination lein aur mild symptoms hone par bhi testing aur isolation follow karein.
