Even before the filming of Virus had begun, director Aashiq Abu said that Revathy was going to play the Kerala health minister. The film is based on the outbreak of the Nipah virus in Kerala last year and KK Shailaja teacher as health minister had a big role to play in dealing with the disease that was killing people. Now, the Virus team has put out a new character poster of Revathy on its page, appearing quite like Shailaja teacher with the glasses, the cotton Sari and even her grave expressions resembling the minister’s."
