'In summary, antibodies against N protein of SARS-CoV-2 WERE NOT DETECTED in 408 (56%) of health care workers of a major hospital for COVID-19 in southern Vietnam.'
1. 'Early preparedness and experience gained from previous pandemics...safety training on COVID-19 patient management and laboratory safety for its designated staff in early January 2020'
When did you receive your COVID19 safety training? @davidshukmanbbc
2. 'To further reduce the risk of nosocomial infection, wearing a medical mask is mandatory for all COVID-19 patients, while being hospitalized.'
For the record please as we're having to deal with an alternative reality of 🇬🇧🇦🇺🇨🇦public 'health' agency airborne transmission denial: all COVID19-facing HCWs were provided with N95 respirators, right? 💙 #COVIDisAirborne

‘HMG PPE guidance on the indications for use of FFP3 respirator relies on two assumptions. First, that its list of AGPs & high-risk areas are exhaustive. Second, that the droplet theory of SARS-CoV-2 transmission is correct.’ @TheBMA@theRCN@KGadhok
‘If either of these two postulates are incorrect & the role of aerosolisation transmission is greater than currently thought, the current triaging system of respirators may result in HMG PPE guidance indicating a less effective form of RPE in a higher-than-expected risk setting.’

'Dr Yvonne Doyle, Medical Director at PHE, said: “NHS staff are under immense pressures and their safety has always been our highest priority.' #FreshAirNHS#COVIDisAirborne
'The NHS Infection Prevention Control group has reviewed the latest evidence and has advised that PPE SHOULD CONTINUE TO BE WORN as laid out in the current IPC guidance, with FFP3 masks required for staff undertaking clinical aerosol generating procedures.'
The twist?
PHE IPC guidance, p2:
'Please note that this guidance is of a general nature AND THAT AN EMPLOYER SHOULD CONSIDER THE SPECIFIC CONDITIONS OF EACH INDIVIDUAL PLACE OF WORK AND COMPLY WITH ALL APPLICABLE LEGISLATION, including the Health and Safety at Work etc. Act 1974.'
@medrxivpreprint preprints since Jan provided multi-nation data allowing modelling of the UK peak casualty time point occurring w/o appropriate preemptive quarantine.
• Health services will be rapidly overwhelmed.
• Critical Care bed numbers would need to double within 1-2 days.
• Peak likely within 50 days of UK entry
