Central government developed guidelines against the leaking of the identity of infected patients to the public by advising authorities to disclose information on the destinations patients visited and how they traveled there, but to withhold any indentifying information, such as their addresses and companies they work for. However, if patient has the potential of infecting large numbers of colleagues at work, then disclosure of such private information is allowed. Traveler information was shared with health facilities and pharmacies to facilitate prompt identification of cases and contacts.
