The omicron variant of the corona virus that has spread to most parts of the world is different from the original strain in many ways. Symptoms, speed of recovery, severity and transmission rate all vary, making it necessary to gather new information to deal more efficiently with the new variant. In the case of Omicron, the previous hallmark symptoms of the coronavirus such as fever, cough and loss of taste or smell are gradually fading away. Instead, other non-dominant symptoms of cold like sore throat, sneezing and runny nose are being seen more prominently.
According to the Zoe COVID Symptom Study, Omicron’s symptoms are more like a cold, especially in people who have been fully vaccinated. The Zo COVID Study is a smartphone app developed during the pandemic to find out how hundreds of thousands of people are feeling daily as they are diagnosed with the coronavirus across the UK. The study helps us understand how traits have changed over time, especially in the case of omicron and delta variants. It also revealed the most prevalent signals in the case of Omicron.
