PULMONARY REHABILITATION IN POST COVID SEQUELAE IN INDIA
Falguni Paul
Introduction: -
An outbreak of pneumonia was reported in Wuhan, Hubei Province, China in December 2019 and quickly spread to all Chinese provinces. 1, 2 The coronavirus disease (COVID-19) pandemic spread through 190 countries within 20 weeks from Wuhan, China, affecting 334,000 populations. This caused more than 14,500 deaths by mid-March 2020. The number of infected people has risen to 1,210,956 in the month of April 6, 2020, with 67,594 associated expirations. 4
India recorded its first COVID-19 infection case on January 30, 2020 in a student from China's capital, Wuhan. In 2020, India reported 360 positive COVID-19 cases from 23 states across the country. 4 in India, the number of asymptomatic cases was higher. On April 4, 2019, a novel coronavirus pathogen was proved to be a novel betacoronavirus. 2 Sub-micron sized viruses, narrated as "organisms at the edge of life", are liable for some of the worst human pandemics in history, like influenza (1918), smallpox (1978), and COVID-19, as of September 17, 2020. 2 The SARS-CoV-2 virus is causative for COVID-19. Nearly 29 million people have been affected by this virus, which caused 936,521 deaths worldwide (WHO, 2020). 2
Corona viruses are single-stranded positive-strand RNA viruses that are known to contain some of the largest viral genomes, up to around 32 kbp in length. Following an augmentation in the number of coronavirus genome sequences available and following efforts to investigate the diversity in the wild, the family Corona viridae now contains four genera. The structure of the coronavirus as given in figure 1 Those species that belong to the genera Alpha corona virus and Beta corona virus can infect mammalian hosts, while those of Gamma corona virus and the recently defined Delta corona virus mainly infect avian species. 3 The highly pathogenic human coronaviruses, Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV), belong to lineage B (sub-genus Sarbecovirus) and lineage C (sub-genus Merbecovirus) of Betacoronavirus. 3
