COVID-19 PREVENTION
In December 2019, the first case of COVID-19 infection was reported in China. The World Health Organization (WHO) declared it a pandemic and proposed protection measures. The measures proposed include frequent handwashing, wearing masks, keeping physical distance, and quarantine for those suspected or already infected. CDC emphasized the significance of these preliminary measures as more investigation continued. In a few months, COVID-19 vaccines were introduced as an effective way of preventing the infection. CDC indicated that vaccination was not supposed to substitute other prevention measures. People were expected to keep a distance of six feet from each other, wash hands, sanitize, and continue wearing masks.
