I strongly suggest buying a few extra bottles for yourself. From what my family in Indo is saying, the price of face masks and sanitizer is rising rapidly in Jawa Barat.
People here in HK are queuing up for HOURS in the hope of getting a box or two of masks or some hand sanitizer.* Tempers flaring. Counterfeit masks being sold. Just what you'd expect in this situation in this environment.
Schools may remain closed past 17th Feb. if Macau's example is followed. Duties of teaching staff differs from school to school: some teachers must report next week for meetings!

Other schools are allowing teachers and staff to stay home through 17th Feb.
* also: dry noodles sell out quickly all over the city, as do tins of fish, frozen foods, etc., NONE of which happened during SARS. Nobody trusts the HK Gov't anymore.
