Despite Uttar Pradesh state reporting 17,138 cases in the last 24 hours, devotees in large numbers thronged Sangam, a confluence of the rivers Ganga, Yamuna and mythical Saraswati to offer prayers at the fair.
Many of the devotees flouted mask and social distancing norms at the festival, even as police officials took necessary actions.
"COVID (-19) is not effective on us. I am not scared at all," said a devotee, Binadeen Tripathi.
The 'Magh Mela' that begins every year in January is considered to be an auspicious time when devotees from across the country reach the fair to bathe in holy rivers, wash away sins and grant salvation from the cycle of life and death.
