Royals don't travel alone. They travel with an entourage of advisers & security. If just one person they meet, or one person with them have COVID they've put at risk, doctors, ambulance technicians, nurses, volunteers, teachers and charity workers in England, Scotland and Wales.
So let's go through some of the places their entourage have gone shall we. Rail workers at a major municipal train station who have contact with the public. One worker gets it, that's a vector of transmission to every person transiting through the station.
An ambulance depot - well lets hope none of those technicians and paramedics are called to an elderly care home, or transport someone with a compromised immune system or god forbid make any contact with medical or care personnel caring for high risk patients.
Oh look - school kids! Let's hope none of those teachers are at risk, or anyone in their family. Let's hope none of those kids get COVID and end up with that kawasaki-like disease medical staff talk about that under 5's get with COVID.
Oh look! No social distancing and no masks again. Infact no masks with the schoolkids in the previous tweet!
And with the royals come curious onlookers in the distance with.......you guessed it! No social distancing!
Here we see them visiting the royal volunteer service who I know for a fact have many retirees in their ranks. Who work in hospitals and other institutions providing medical care - and with the elderly.
