You really should be worried about every country. Even countries that do seem to be facing it head on, still have hard time with testing capacity.
For example here we have ~250 known cases, but guys in the Ministry of Health acknowledge that there are at least triple that amount if not more, simply because they both can't test everyone and many people can carry that and not exhibit any symptoms. For example teens and such are already almost "immune" to it anyway and may not even show anything, but they still can carry and pass this shit on even in a brief time they are sick.
