Quite so, with about a further 350,000 people per day crossing the causeway to/from JB, and another 50-100,000 crossing at Tuas total. Screening has been implemented for all travellers, to whatever extent that is effective. Interestingly, while Indonesia has been quiet on the subject, screening is being conducted in JKT and in BLI so they are being active.
