The Delta variant was identified in the ending of 2020 and was a result of a mutation to the original Covid-19 virus. It spread fast and soon became the dominant strain in both India and Britain. At this time the Delta variant is the dominant strain in over 100 countries including the Unites States and Europe.
This new variant has specific mutations on the ‘spike’ protein which make it easier for the virus to infect humans. This has resulted in the delta variant to be much more contagious than the alpha variant. Experts are recommending masking up even if you are vaccinated.
Symptoms of the delta variant are similar to the original strain and includes fever, headache, cough and runny nose. Loss of smell has a lower incidence with this strain. Vaccinated people have milder symptoms resembling a common cold or may even be asymptomatic.
Although breakthrough cases have been seen in vaccinated people, the numbers show cases rising in areas that have more unvaccinated people. People who have not yet been vaccinated are at a higher risk to become infected and spread the virus which is why it is our social responsibility to get vaccinated and protect ourselves and others
