There are measures beyond those outlined above in the NICE document, both in terms of the symptoms that can be managed in the community and the treatments that can be provided, but these involve specialist advice or prescription medicines so are not detailed here.
It is worth bearing in mind that not all patients with the above symptoms will have Covid-19, but without testing, it is difficult to tell. Other symptoms that may point towards Covid-19 include aching muscles, sore throat, headache and loss of sense of smell, but the virus seems to be able to cause a wide range of symptoms, so pharmacy staff should advise customers seeking advice or product recommendations for their loved ones to use information from the NHS website and the NHS 111 online coronavirus service. Caution is needed, as individuals can deteriorate quickly and need urgent admission to hospital in order to manage the pneumonia that can develop.
