There is no specific approved treatment for this disease, Vaccines are being developed, available and given.
Healthcare providers are mostly using a symptomatic approach, meaning they treat the symptoms rather than target the virus, and provide supportive care (e.g. oxygen therapy, fluid management) for infected persons, which can be highly effective.
In severe and critically ill patients, a number of drugs are being tried to target the virus, but the use of these need to be more carefully assessed in randomised controlled trials. Several clinical trials are ongoing to assess their effectiveness but results are not yet available.
As this is a new virus, only few and small quantities of the vaccine will initially be available. Although work on a vaccine is still ongoing by several research groups and pharmaceutical companies worldwide, as mutations develop this is an ongoing exercise.
