A recent study conducted by the Christian Medical College, Vellore, suggests that Indians who have recovered from COVID-19 experience more severe lung functioning issues compared to Europeans and Chinese individuals.
According to the study, these lingering symptoms may persist for up to a year in some cases, while others may have to live with impaired lung function for the rest of their lives.
The research highlights that Indian patients in the study exhibited a higher prevalence of comorbidities and greater damage of lung function than their European and Chinese counterparts. This study, hailed as the first of its kind for Indians, sheds light on the long-term impact of COVID-19 on lung health and overall quality of life.
A study conducted by the Indian Council of Medical Research (ICMR) in 2023 revealed that approximately 6.5% of individuals hospitalised with COVID-19 succumbed to the disease within the following year. This mortality rate was seen to be consistent with data observed globally.
The study analysed data from 14,419 patients across 31 hospitals, encompassing individuals hospitalised since September 2020. The infections in these cases were presumed to have been caused by various variants of the coronavirus, including the original strain, delta, or omicron.
Further, the study focused on outcomes among patients with moderate to severe disease. It uncovered that 17.1% of participants experienced post-COVID-19 conditions, such as lethargy, breathlessness, and cognitive abnormalities like brain fog and difficulty concentrating.
Notably, individuals who experienced these post-COVID-19 conditions were nearly three times more likely to succumb to the disease.
Dr Suranjit Chaterjee, senior consultant of internal medicine at Indraprastha Apollo hospital, New Delhi, who is not associated with the study, said: ¡°From the evidence so far, long Covid may happen even in people who have had bouts of mild Covid-19. The symptoms improve with therapy and pills.¡±
