Tough Luck?

I had the worst luck as a project manager ever. Within a month, I have one developer's wife who needed to go to hospital because of stomach problem, one tester who needed immediate operation, one developer who had lung problem and waiting for operation, another developer who had diagnosed with virus. I mean how many project manager had to deal with that many people got sick in a month and all of them are serious sickness. :( Problem is I can't just replace them because developers need time to ramp up. Last project, both my tester and developer left the company. I have only one conclusion. The problem is me.
