What public health measure is NOT suggested for controlling the spread of COVID-19?

The measure that is not suggested for controlling the spread of COVID-19 is related to large public gatherings. Public health guidelines have indicated that large gatherings can significantly increase the risk of virus transmission because they facilitate close contact among individuals and can lead to superspreading events.

In contrast, wearing masks, practicing social distancing, and frequent hand washing are all recommended practices aimed at minimizing the spread of the virus. Wearing masks helps reduce the transmission through respiratory droplets, social distancing lowers the chances of coming in close contact with infected individuals, and frequent hand washing with soap and water or using hand sanitizer helps eliminate the virus from surfaces and prevents it from entering the body. All these measures have been supported by health organizations to manage and control outbreaks effectively.
