But if the number of cases increases its very difficult to manage. Recent reports indicate Kerala might face shortage. Karnataka which also had enough oxygen can face a deficit in coming days if the cases keep up.

There is so much focus on oxygen, but is scaling healthcare facilities actually a solution?

It seems that even in rich countries hospital capacity is overwhelmed as soon as infection rate is out of control.

No, because a significant proportion of people who enter the hospital (and especially intensive care) will still die, even with proper care.

The biggest problem is that it is a really tough sell if you run out of capacity. Even if it would be better to use that capacity for other cases.
