English supermodel Naomi Campbell's tweet congratulating `malaria` for winning the 2014 Nobel Peace Prize has gone viral on social media.

Campbell was apparently meaning to wish Pakistani girls' education activist Malala Yousafzai , but the message backfired when she wrote the word `malaria` instead of Malala, Dawn online reported Saturday.

"Congratulations malaria on your #noblepeaceprize #2014 #Respect #joy #ithalljuststarted ??" she wrote in the tweet.

According to the report, Campbell had originally posted the message on her Instagram Saturday, but it also automatically went to her Twitter account.

She also misspelt Nobel as `noble` but that could be an error due to the auto-correct feature available in smartphones.

While people were quick to notice the slip-up, Campbell had apparently not noticed for hours after posting her message as the mistake was not corrected.

`Naomi Campbell calls Malala, malaria. Maybe because she comes from the SWAT region in Pak,` tweeted @ajith27.

`Malaria gets Peace prize and Elephantiasis becomes endangered pachyderm,` wrote @nirvana74v.

Another tweet by @TheAzzo read: `Malaria is now trending in London. Naomi Campbell is going to start a mosquito-related panic.`

Malala was named the joint winner of the 2014 Nobel Peace Prize Friday along with Indian child rights activist Kailash Satyarthi.
