The question still remains exactly how Delta affects the human body differently than other variants.
To start with, the symptoms appear to be different from the traditional COVID symptoms we were told to look out for at the start of the pandemic. Previously fever, persistent cough and loss of taste or smell were the most common symptoms to look out for. But now, a headache is reported to be the most common symptom, followed by a sore throat, runny nose and fever.
It is still unclear whether the Delta variant causes more serious illness than previous strains. Certainly, people with Delta are getting pneumonia and severe illness and some are dying – but the question we need to answer is, are they dying at the same rate as before? We would hope not.
What is clear, however, is that the highest spread of virus and severe outcomes is in those places with low vaccinations rates. This clearly highlights the importance and immediate benefits of achieving the highest possible COVID-19 vaccine uptake, especially in outbreak areas.
