Impact of COVID-19 and comorbidities on health and economics: Focus on developing countries and India.

ABSTRACT

BACKGROUND AND AIMS: Presence of comorbidities in patients with Coronavirus disease 2019 (COVID-19) have often been associated with increased in-hospital complications and mortality. Intriguingly, several developed countries with a higher quality of life have relatively higher mortality with COVID-19, compared to the middle- or low-income countries. Moreover, certain ethnic groups have shown a higher predilection to contract COVID-19, with heightened mortality. We sought to review the available literature with regards to impact of COVID-19 and comorbidities on the health and economics, especially in context to the developing countries including India. METHODS: A Boolean search was carried out in PubMed, MedRxiv and Google Scholar databases up till August 23, 2020 using the specific keywords, to find the prevalence of comorbidities and its outcome in patients with COVID-19. RESULTS: All available evidence consistently suggests that presence of comorbidities is associated with a poor outcome in patients with COVID-19. Diabetes prevalence is highest in Indian COVID-19 patients, compared to other countries. Majority of the patients with COVID-19 are asymptomatic ranging from 26 to 76%. CONCLUSIONS: Universal masking is the need of hour during unlock period. Low-income countries such as India, Brazil and Africa with less resources and an average socio-economic background, must adopt a strict policy for an affordable testing programs to trace, test, identify and home quarantine of asymptomatic cases. Despite the huge number of COVID-19 patients, India still has low volume research at the moment.
