Even in the early throes of the Indian third wave, reports of different COVID19 symptoms began to circulate amongst social media.
Updated COVID19 symptoms as per the CDC now include:
- Muscle or body aches
- Sore throat
- Congestion or runny nose
- Nausea and vomiting
How does it affect hospitalisations and the death rate?
A Public Health Scotland study found that the risk of hospital admissions was almost doubled with Delta vs. Alpha.
Amongst those vaccinated with Pfizer or AstraZeneca, the Public Health England study reported that those with one dose of vaccine were 75% less likely to be hospitalised and those with both doses are 94% less likely to be hospitalised when compared to the unvaccinated population.
How does it respond to vaccines?
A report published by Public Health England indicated that the variant is moderately resistant to vaccines, especially just the first dose. A single dose of AZ or Pfizer reduced a person’s risk of developing symptomatic illness by 30% (vs. 50% for the Alpha variant). A second dose of AZ increased protection to 60% (compared to 66% for Alpha). Two doses of Pfizer were 88% protective against the variant (compared to 93% against Alpha).
No studies are available about the Sputnik or Sinopharm response to the new variant.
