The Covid-19 pandemic has been a challenging situation to deal with for all countries and people. Experts from the WHO declared recently that the pandemic is here to stay and that the virus will more likely continue to evolve and mutate. The virus will remain with us just like other viruses, such as the flu or influenza. However, the health experts explained that we had a chance to eradicate the virus at the beginning of the pandemic, but unfortunately, we did not act fast enough. The Sars-CoV-2 virus spread worldwide, and as it infected new human hosts, the virus continued to mutate and evolve. Health experts are keeping an eye on all variants, and it has been a complex task trying to predict the evolution of the virus from the beginning up to now.
The WHO classified Delta as a ‘variant of concern’
One of the characteristics of all viruses is that they evolve through mutation, and new strains emerge. The Delta strain has been classified as a variant of concern due to its high transmissibility rate. It can trigger severe illness, with different symptoms compared to the original virus. According to the COVID symptom study created by a group of doctors and scientists from Massachusetts General Hospital, Harvard T.H Chan School of Public Health, King’s College London, Stanford University School of Medicine, and ZOE, infections with the Delta variant have a list of common early symptoms we should not miss.
Early Symptoms of the Covid-19 Delta variant:
According to the study’s researchers, early symptoms of the Delta infection on those vaccinated are headaches, sore throat, runny nose, fever, and cough. For those unvaccinated, early symptoms of an infection with the Delta variant are similar to those associated with other Covid-19 variants.
Fully vaccinated people infected with the Delta strain experience symptoms similar to a common cold. Other symptoms of the Covid-19 virus are fatigue, breathing difficulties, loss of taste and smell, diarrhea, and nausea.
