- This guideline is for those diagnosed with COVID-19 infection
- COVID-19 is a viral infection.
- COVID-19 antivirals may be considered for patients at risk of progressing to severe disease.
- Secondary bacterial infection appears uncommon in COVID-19 patients.
- Differentiating viral COVID-19 infection versus a secondary bacterial COVID-19 pneumonia:
- Viral COVID-19 infection more likely if;
- history of typical COVID-19 symptoms for about a week
- severe muscle pain (myalgia),
- loss of sense of smell (anosmia), taste (dysgeusia)
- breathless but has no pleuritic pain
- history of exposure to known or suspected COVID-19, such as a household or workplace contact.
- Secondary bacterial COVID-19 more likely if;
- became rapidly unwell after only a few days of symptoms.
- does not have a history of typical COVID-19 symptoms.
- purulent sputum.
- pleuritic pain.
- underlying chronic lung disease with history of secondary bacterial infection in winters e.g. in acute infective exacerbation of COPD.
- Doxycycline is preferred because it has a broader spectrum of cover than amoxicillin, particularly against Mycoplasma pneumoniae and Staphylococcus aureus, which are more likely to be secondary bacterial causes of pneumonia during the COVID-19 pandemic.
- Check pulse oximetry.
- Use the following symptoms and signs to help identify patients with more severe illness to help make decisions about hospital admission:
- severe shortness of breath at rest or difficulty breathing.
- reduced oxygen saturation levels measured by pulse oximetry.
- Severe comorbidity.
- Signs of overt sepsis.
- At convalescence, ensure COVID-19, influenza and pneumococcal vaccinations up to date.
- For further information on COVID-19 resources can be found on the HSE Health Library Ireland website.
* Alternative doxycycline dose: 100mg every 12 hours.
In non-severe infection, 200mg stat then 100mg every 24 hours can be considered.
- Honey may help to relieve symptoms of cough.
- Consider short-term use of codeine linctus in people 18 years and over to suppress coughing if it is distressing.
- Consider analgesia: paracetamol (or ibuprofen where appropriate).
- Ensure adequate hydration by drinking plenty of fluid.
- Advise to consult pharmacist for symptom relief.
