Although CDC said that further quarantine is not necessary and has sent the patient home, different opinions over the dismissal have emerged among medical professionals. We explain here on CTS.

Regarding Taiwan's first case of NDM-1, CDC deputy director-general, Shih Wen-yi says, the bacteria were found in the patient's intestinal tract but the patient shows no symptoms of infection while the "superbug" is not in his urine samples or gunshot wound.

Since NDM-1 is not an airborne bacteria, the patient does not need to be quarantined and can return to his normal life as long as he maintains a healthy lifestyle and good hygiene habits and returns to CDC for regular check-ups.

However, debates over the patient dismissal have spread among medical experts.

Former CDC director-general Su Ih-jen, says that the patient should be quarantined until there's no NDM-1 found in him.

He says it is possible for the bacteria to pass on and replicate its drug-resistance to native bacteria through excrement, and therefore cause greater infection in Taiwan.

Huang Li-min, doctor of the Department of Pediatrics of National Taiwan University Hospital has a different opinion.

He says that since "superbug" is resistant to most antibiotics, treating the patient now is not necessary unless the onset of symptoms has occurred.

Minister of the Department of Health, Yaung Chih-liang, says that according to the law, patients without symptoms need not to be quarantined.

The best way to prevent the superbug from spreading is to strengthen the monitoring system within hospitals and good personal hygiene habits.
