Are there any specific medicines to prevent or treat COVID-19? 是否有预防或治疗COVID-19的特效药?

To date, there is no specific medicine recommended to prevent or treat the new coronavirus, also known as COVID-19.

However, those infected with the virus should receive appropriate care to relieve and treat symptoms, and those with severe illness should receive optimized supportive care. Some specific treatments are under investigation and would be started under medical supervision and care.

到目前为止,还没有特别推荐的药物来预防或治疗这种新型冠状病毒,也被称为COVID-19。

No, antibiotics do not work against viruses, but they work on bacteria.

COVID-19 is a virus and, therefore, antibiotics should not be used as a means of prevention or treatment. However, if you are hospitalized for the COVID-19, you may receive antibiotics because a concurrent bacterial infection is possible whilst having COVID-19.

不,抗生素对病毒无效,但对细菌有效。

COVID-19是一种病毒,因此,不应将抗生素用作预防或治疗手段。然而,如果你因为COVID-19而住院,你可能会接受抗生素治疗,因为同时感染细菌是可能的。

Is the antimalarial agent Chloroquine effective for the treatment of COVID-19? 抗疟药氯喹对COVID-19的治疗有效吗?

The Take-Home Points:

Antimalarials like chloroquine and hydroxychloroquine are currently being studied for their effectiveness and safety when used to treat COVID-19. While Chloroquine may be purchased from a licenced pharmacist in Singapore for the prevention of malaria, we do not recommend self-medication for treatment of COVID-19 without proper medical assessment and evaluation. If you suspect that you could have COVID-19 infection or experiencing COVID-19 symptoms, seek medical attention immediately.

关键点:

抗疟疾药(如氯喹和羟基氯喹chloroquine and hydroxychloroquine)目前正用於治疗COVID-19时有效性和安全性的研究。虽然可以从本国药剤师那里购买氯喹来预防疟疾,但我们並不建议您在没有适当医生检验的情况下自行用药治疗COVID-19。如果您怀疑自己可能感染了COVID-19或出现了相关症状,请立即就医。
