I'm not downplaying the severity of this, because it looks to be 7-30 times more deadlier than the flu, but doctors are a little bit of a different case. This article below gives a good 1st hand illustration of the working conditions during the outbreak, and what it was like dealing with the virus.
The best way to strengthen your immune system is to get proper rest and sleep. Those doctors in Wuhan were working 12 hours straight with no breaks to eat or use the washroom, as they didn't have enough PPE to change out. They were also exposed to incredible amounts of the virus, for some once they were infected, they stopped wearing PPE altogether. Not too mention the stress of seeing their patients die everyday.
Since Jan 7, when we received the first patient, no one took any leave. We took turns to work in the ICU. Even pregnant medical staff did not take leave. After the epidemic got worse, none of the medical staff ever went home. We rest in a hotel near the hospital or in the hospital.
In the segregated ward, we wear level-3 protective gear. One shift is 12 hours for a doctor and eight hours for a nurse. Since protective gear is in a shortage, there is only one set for a medical staff member a day. We refrain from eating or drinking during our shift because the gear is no longer protective once we go to the washroom. The gear is thick, airtight and tough on our body. It felt uncomfortable at the beginning, but we are used to it now.
