SARS-CoV-2 delta (B.1.617.2) first detected in England in March, 2021
Suspected to cause more severe disease than alpha (B.1.1.7)
Determining the relative risk of hospital attendance
England between March 29 and May 23, 2021

Infections
n = 43,338 COVID-19-positive patients
Most patients were unvaccinated, 32,078 (74·0)
Median age 31, (IQR, 17 – 42)
Delta = 8,682
Alpha = 34,656
Admitted to hospital or sought emergency care within 14 days of positive test
Delta = 498 (5.7%)
Alpha = 1,448 (4·2%)
Adjust for age, sex, ethnicity, deprivation, recent international travel, area of residence, calendar week, and vaccination status
HR for attendance at emergency care or hospitalisation = 1.45
HR for hospital admission = 2.26
In the subgroup of vaccinated patients
No significant difference between variants for emergency visit or hospitalisation
Interpretation
This large national study found a higher hospital admission or emergency care attendance risk for patients with COVID-19 infected with the delta variant compared with the alpha variant.
Results suggest that outbreaks of the delta variant in unvaccinated populations might lead to a greater burden on health-care services than the alpha variant.

92% for the Oxford-AstraZeneca vaccine
UK rates
47.9 million people, (88%) aged 16 and over, first dose of a vaccine
42 million people, (78%) aged 16 and over, have had a second
Dr Gavin Dabrera, PHE
We already know that vaccination offers excellent protection against Delta and, as this variant accounts for over 99% of Covid cases in the UK, it is vital that those who have not received two doses of vaccine do so as soon as possible
It is still important that if you have Covid symptoms, stay home and get a PCR test as soon as possible
