Under the scheme, the government has invited applications from students of medical, dental, Unani and Ayurveda colleges in the state to apply as volunteers in the fight against Covid-19. Apart from the 271 colleges spread across the 13 districts of the state, the government is also opening the scheme to students of associated courses. The scheme also welcomes doctors and medical professionals from private hospitals to serve as volunteers in the quarantine centres. The warrior volunteers will get priority in medical and health department recruitments that the state government undertakes in the future. /IANS
