UCL team awarded £1.4m to assess Covid-19 infection risk in BAME communities

A team led by Dr Robert Aldridge, from UCL (University College London), has been awarded £1.4m to recruit about 12,000 people from BAME groups to add to the 25,000 already in its “virus watch” study, previously funded by UKRI and NIHR. It will examine infection incidence among BAME communities and the contribution of factors such as overcrowding, migration status and occupation.

“One of the things that we’re concerned about in the migrant group in particular is barriers in access to healthcare and racism, structural discrimination, and whether that’s playing a factor,” said Aldridge. “Do they get a poorer level of care than both non-migrant minority ethnic groups and the white British groups?”

He said that the work would include examining the reduction in access to healthcare arising from the hostile environment.

The researchers said they would start publishing data and recommendations as soon as possible given the urgent need for action ahead of a feared second wave of the pandemic rather than wait until their studies were concluded.

Household Transmission of Seasonal coronavirus infections

Woman sitting with feet up at home.

This analysis showed that most seasonal coronaviruses appear to be acquired outside the household and there is relatively modest risk of onward transmission within the household.

Black, Asian and Minority Ethnic groups in England are at increased risk of death from COVID-19: indirect standardisation of NHS mortality data

We used NHS data of patients with a positive Covid-19 test, who died hospitals in England from March 1 to April 21 this year – which included data on age, region and ethnicity.

Our findings support an urgent need to take action to reduce the risk of death from Covid-19 for BAME groups. Actions to reduce these inequities include ensuring an adequate income for everyone so that low paid and zero-hours contract workers can afford to follow social distancing recommendations, reducing occupational risks such as ensuring adequate PPE, reducing barriers to accessing healthcare and providing culturally and linguistically appropriate public health communications.

Seasonality and immunity to laboratory-confirmed seasonal coronaviruses (HCoV-NL63, HCoV-OC43, and HCoV-229E): results from the Flu Watch cohort study

Our results provide evidence that HCoV infection in England is most intense in winter, but that there is a small amount of ongoing transmission during summer periods. We found some evidence of immunity against homologous reinfection.

A review: Automated and partially-automated contact tracing

This analysis found no epidemiological studies comparing automated to manual contact tracing systems and their effectiveness in identifying or notifying contacts, and that automated contact tracing only has potential to reduce transmission with sufficient population uptake.

Asymptomatic SARS-CoV-2 infections in community settings

Symptomatic/Asymptomatic diagram

In this analysis we found that the asymptomatic proportion of SARS-CoV-2 infections is relatively low (11%) when estimated from methodologically-appropriate studies. We have been continuing to update this work by including updated papers at they are published are now finding a figure of around 20% asymptomatic.

COVID-19 and homelessness in England

Our model quantified how accommodation can mitigate the impact of the COVID-19 pandemic on the homeless population of England, and reduce the burden on acute hospitals.
