the probability of selecting the "best" does not converge to 1 (as the sample size n goes to infinity) for leave-v-out cross-validation unless the proportion v/n approaches 1

More and more patients are being admitted to the intensive care unit. Despite the heroic efforts of all staff (doctors, nurses, specialists, etc) patients continue to inevitably die. The truth is that anti-viral treatments and vaccines are not expected to have any effect, even at high doses. It is a great fear among the staff. The infection risk is very high among the doctors and health staff.

Staff are starting to leave and many are opting to retire or apply for holidays. The truth is that mortality is even higher than what is being reported by the authorities, at least in the hospital where I work it. It is killing three to four patients daily, and it has been going on for more than three weeks. It is a shame and there is great fear here. Increasingly younger patients aged 20 to 30 years are dying before our helpless eyes and there is great sadness among health professionals here.

real lack of information

there is a hospital closed because of a death related to the porcine influenza. In the papers they recognise only two people dead for that cause.

19 people dead in Oaxaca, including a doctor and a nurse.

panic comes from a lack of information
