Introduction:
A new strain of coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first identified in Wuhan, Hubei province, China, in December 2019. Since then, the virus spread all over the world rapidly and became the reason for millions of deaths in the world. The disease caused by SARS-CoV-2 was termed as Coronavirus Disease 2019 (COVID-19) and was declared a global pandemic by the World Health Organization on March 11, 2020 [1]. Severe COVID-19 patients suffer from severe critical illness with pneumonia, acute respiratory distress syndrome (ARDS), and multiorgan failure [2]. This novel coronavirus disease had a dangerous impact on patients, families, healthcare systems, and communities due to the lack of accurate medicine and vaccines, especially in the year 2020 and 2021. To decrease the transmission of the virus, a heavy lockdown was implemented in almost all the nations of the world and global economic activities were in turmoil.
The SARS-CoV-2 virus spreads from person to person through small respiratory droplets and mutates over time. There are several variants of SARS-CoV-2 developed from several mutations. Alpha, Beta, Gamma, Delta, and Omicron variants are remarkable variants of SARS-CoV-2. The Delta (B.1.617.2) variant first emerged in India at a time of low vaccine coverage and was the most dangerous among all the variants of the globe due to high transmissibility, the severity of illness, and death rate [3]. In May 2021, the delta variant of SARS-CoV-2 was the most dominant variant in maximum countries of the world [6]. The poor recovery of COVID-19 patients suffering from heart failure, diabetes, hypertension, malignancy, and chronic kidney disease has been reported [5]. In this case report, we will discuss how the patient recovered from severe COVID-19 symptoms after about six months’ rest and treatment.
