This is also the most intense outbreak ever. Medical supplies we virtually take for granted in the US would be in short supply over there already, but even more taxed by the number of patients.
Which would likely mean that they are being re-used, perhaps cleaned (perhaps badly) and re-used, and possibly damaged or contaminated in the process.
If they are being sprayed down, there is a possibility droplets with the virus are being distributed inside the PPE before it is re-used.
Can the virus infect transdermally? We don't know, but that might explain how health care workers re-using washed, but still contaminated PPE might become infected--especially if the virus made it to the inside of a glove.
Under the circumstances, and with health care personnel likely overworked, mistakes will be made, accidents will happen, and people will have some lapse in protocol which will cause them to be infected.
