About one-third of elderly people reported loneliness. The social distancing and quarantine measures implemented against the 2019 Coronavirus disease (COVID-19) pandemic in particular have drastically affected the elderly group more susceptible to loneliness. Research evidence has shown that loneliness has substantial negative impact on both physical and psychological well-being. While there is no consensus on screening for loneliness, several assessment tools have been used for clinical diagnosis and follow-up. The subtypes of loneliness include social loneliness, emotional loneliness, and social-cum-emotional loneliness. Current treatment strategy focuses on improving life quality and satisfaction of people suffering from the absence of social relationships and promoting their social connections by group activities.
