It's spread from person to person, not electronic parts from a slow boat to person.

It's a virus, so effectively not something you can 'kill' with some sort of spray.

If you think you're at risk, then prevent ways of the virus entering your body. Wear a mask to avoid inhalation of airborn viral particles. Wash your hands after touching surfaces, to remove any viral contaminants from your skin before you (say) put your hands near your mouth.

But, basically, we're pretty much doomed to watching this run its course, because people are stupid and the chances of preventing further spread - particularly with air travel between countries and the difficulty in telling if people are infected or not - is essentially zero. We're just going to have to wait and see how quickly things take off. But my bet is that the Olympics are cancelled, we see fairly major epidemics - particularly in Asian countries - and a worldwide loss of life in the tens of thousands. Perhaps more. But, I'd love to be wrong on this.

It probably wouldn't hurt to spray disinfectant on it.
