The Kappa variant is one of the three sublineages of lineage B.1.617. It is also known as lineage B.1.617.1, 21B or 21A/S:154K, and was first detected in India in December 2020. By the end of March 2021, Kappa accounted for more than half of the sequences being submitted from India. On 1 April 2021, it was designated a variant under investigation (VUI-21APR-01) by Public Health England. It has the notable mutations L452R, E484Q, P681R.
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was identified in Wuhan, China, in December 2019. The disease has since spread worldwide, leading to an ongoing pandemic.
Symptoms of COVID-19 are variable, but often include fever, cough, headache, fatigue, breathing difficulties, and loss of smell and taste. Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms. Of those people who develop symptoms noticeable enough to be classed as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% suffer critical symptoms (respiratory failure, shock, or multiorgan dysfunction). Older people are at a higher risk of developing severe symptoms
