Defining fever

Fever threshold

Uninfected volunteers (twins), n = 1,089

Hospitalised, n = 1,227

Community based positives, n = 3,972

Results

Among unaffected volunteers

Lower BMI (p=0.001), and older age (p less than 0.001) associated with lower basal temperature

Basal temperature showed a heritability of 47%

In COVID-19+ participants

Increasing age associated with lower temperatures (p less than 0.001)

For each additional year of age, participants were 1% less likely to demonstrate a fever

Ageing affects temperature in health and acute infection

Older people with COVID-19 were also less likely to have a fever reaching 37.8°C

Current health guidelines, 37.8°C or more should self-isolate

Using a threshold of 37.4°C for over 65s is as sensitive and specific a sign of infection as 37.8°C in adults under 65

We’re very worried

All it’s going to take is a couple more mutations on top of that, and you’re really going to have to start worrying

Novavax trial, Previous infection did not provide full immunity to B.1.351

Efficacy against old strain = 95.6%

Efficacy against UK variant = 85.6%

Efficacy against SA variant = 60%

United Kingdom, South Africa, Brazil all in US

U.K. variant, B.1.1.7, 430 cases

Brazil variant, P.1., Minnesota

Jay Butler, Centers for Disease Control and Prevention

If a more transmissible strain becomes dominant, herd immunity, 80 to 85 %

Marc Lipsitch, Harvard, School of Public Health

We will not be for decades dealing with a pandemic

The concern is whether it will be a year or three years until we can make enough vaccines against enough strains to get this under control
