We know health workers are high risk for #COVID19

High quality PPE can protect us, but filtration masks hurt like hell, cost £££ and are bad for the environment

What's the answer?

We show PAPR like @PeRSoPPE are well tolerated, sustainable and safe

1/
frontiersin.org/articles/10.33…
After rolling out @PeRSoPPE at @UHSFT we asked HCWs about their experience, and it was much preferred for comfort and feeling of safety over other forms of PPE

Patients (particularly the elderly) preferred it too

(thanks Paul Elkington MBE for being such a glamorous model)

2/
An economic analysis found that they are more cost efficient than filtration masks, or a mix of filtration + surgical masks over almost all scenarios

Also significantly reducing waste (we can be safe and not kill the turtles🐢)

3/
We also found that after roll out of @PeRSoPPE our hospital dropped from mid table staff absences to the lowest vs comparable hospitals, indicating their effectiveness at reducing infection

4/
Given #COVID19 isn't going anywhere, and HCWs remain at risk from #COVIDisAirborne transmission, sustainable and effective protection is needed

This is good evidence PAPRs such as @PeRSoPPE for high risk environments are the answer

@PeRSoPPE @FrontMedTech @UoS_Medicine Oh and most importantly if you wear a PAPR instead of a facemask you don't have to smell your own coffee breath all day

This alone should be a good enough reason for the #NHS to invest and protect staff wellbeing

Time for a quick round up of the bizarre world of #COVID19 epidemiology in children in England right now

Hold on to your hats, it's an interesting picture and despite what you might have heard, it's not all bad news! 🧵

1/
Firstly @UKHSA clinical cases

Case ballooned in secondary school age children after a blip on school opening, and after a slight dip (?) now up again

Primary children appeared to continue summer trend upwards, with small school re-entry blip. Now maybe oscillating or up?

2/
This trend is matched by school ages in the @ONS population sampling data

Huge prevalence last week in secondary school age (>8%!), and less than half of this in primary school age

Remember we've been saying for 18m young children are different to older children?

How worried should we be about #COVID19 in children?

Covid is a threat to children. But it’s not an extraordinary threat. In fact, it’s very ordinary.

In general, the risks from being infected are similar to the other respiratory viruses you probably don’t think much about

1/
In fact, for smaller children (pre school) viruses like RSV are much more likely to result in hospitalisation and severe disease

We are heaving with RSV and other viruses in children’s ED, but despite record numbers of community cases are still seeing very little #COVID19

2/
The children who are most likely to suffer from #COVID19 are those who suffer from other resp viruses, such as those with severe neurodisability or lung/heart disease

The risk is similar to that from other viruses, but can be significantly reduced by vaccination if available

The study we've all been waiting for

Using data from >50,000 #COVID19 contacts, vaccinated people are less infectious EVEN with Delta, and EVEN if CT count is the same

Also, kids appear less infectious and less susceptible, including with Delta

1/
medrxiv.org/content/10.110…
The effects of vaccination on reducing infectiousness are strongest earlier on and wane slightly with time

Somewhat less effective for Delta than Alpha

Effects on reducing susceptibility to infection appear stronger and remain quite well preserved, with some waning

2/
Data also clearly shows an age dependent effect

-Much lower rates of secondary infection from child index cases
-Mower secondary infection in child contacts

This remains true across settings including education, except "Events / activities" (?nature of contact)

It's over 3 weeks since schools reopened in England after summer - what's happening in the #COVID19 data?

I'll be honest with you, it's a mess

I've got no idea what's going on - the data is a bit baffling

Lets take a look... 🧵

1/
The headlines are mostly about PHE cases data

These have been increasing in most age groups since early August, with a slight flattening after reopening of schools, now rocketing in 10 - 15yo

Interestingly, sloping downwards in the <5s

Maybe a school effect on cases?

2/
We know the start of school based testing does botch the trends somewhat, which was always going to be difficult to disentangle

In contrast to case numbers, positivity is actually tanking, especially in people reporting symptoms

Increases in Rhinovirus etc boosting testing?

Proud our new analysis of the 2nd wave (mainly Alpha) of #COVID19 in children in the UK is now available!
Headlines:

- No evidence of increased severity
- Over 30% admissions <1y
- Over 40% admissions had comorbidities
- Over 20% incidental positives

assets.publishing.service.gov.uk/government/upl…

1/
Compared to wave 1, the acuity was lower - less unwell on admission, and less respiratory support

There were more admissions, likely representing a higher case count and lower threshold for admission

2/
Children with no comorbidity made up 60% of admissions, and of these >40% were <1yo, likely representing our lower threshold to admit infants

Indeed, children w/o comorbidities were less unwell and required much less support

The best data by far on #LongCovid is out from the ONS

For kids, the news is incredibly reassuring - parents minds should be put to rest

Rates of common symptoms after #COVID19 at 12 w for kids are extremely low (0% to 1.7%) compared to controls

ons.gov.uk/peoplepopulati…

1/
Previous ONS statistics have been widely misused, and difficult to interpret due to unavailable methods

This is all put to bed now. Excellent, transparent comparisons with a suitable control group.

Importantly, it includes COVID cases which would be missed by NHS testing

2/
One statistic stands out

At both 4 and 12 weeks, MORE children aged 2 - 11y in the control group were experiencing symptoms than in those who tested positive for #COVID19
