Omicron
In India, in December 2021, a new type of corona infection, the omega-3 infection, was discovered in a South African country. Due to the spread of the virus, the spread of corona has increased in most states including Tamil Nadu, Madhya Pradesh, Uttar Pradesh, Gujarat, Maharashtra, Andhra Pradesh, Karnataka and Delhi. Due to this, the state governments imposed night curfew and full curfew on weekends.
Relaxations
This was followed by the end of January last night, when the night curfew was lifted and various relaxations were granted following the impact of the third wave of the Corona. As part of this, schools and colleges have been opened in states including Tamil Nadu and classes are being conducted with full precautionary measures.
Danger to China
Meanwhile, in neighboring China, which is considered the source of the corona infection, the pace of corona spread has been increasing over the past few days. After about two years the daily incidence of corona in the country is increasing. Due to this, a complete curfew has been imposed in cities including Changchun and Shanghai.
The fourth wave
In this case, it is said that due to the corona virus infection spreading in China, there is a possibility of corona re-emergence in India. There is a growing demand for intensive monitoring of travelers from China to India. If the virus spreads in China and spreads to India, it could be the fourth wave of corona infection.
