The COVID-19 pandemic has had far-reaching consequences on almost every human way of life by interrupting the usual flow of existence. The first case of Coronavirus infection was identified in Wuhan, China, and it spread like wildfire throughout the globe, forcing life to come to a halt. Because of the spread of these viruses, schools have been shuttered, and students are expected to stay at home and learn online. This leads to a significant increase in internet usage among children and teenagers. This study investigates the impact of social media and the internet on addiction and social isolation levels among adolescent children during and after the pandemic. A convenience sample of 90 school children was used in this investigation. The information was gathered using online questionnaires that comprised a demographic question, a social media addiction scale, and a social isolation scale. There was a substantial medium negative and significant relationship between social media use and social isolation, indicating that social isolation decreases as social media addiction rises. There was no significant difference in offender scores discovered. Both boys and girls are moderately addicted to social media, which impacts the reduction of social isolation.
