For those who test positive for COVID-19 but do not have any signs or symptoms, WHO now suggests 5 days of isolation in the absence of testing, compared to 10 days previously.
Isolation of people with COVID-19 is an important step in preventing others from being infected. This can be done at home or at a dedicated facility, such as a hospital or clinic.
The evidence considered by the guideline development group showed that people without symptoms are much less likely to transmit the virus than those with symptoms. Although of very low certainty, evidence also showed that people with symptoms discharged at day 5 following symptom onset risked infecting three times more people than those discharged at day 10.
Review of COVID-19 treatments
WHO has extended its strong recommendation for the use of nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’).
Pregnant or breastfeeding women with non-severe COVID-19 should consult with their doctor to determine whether they should take this drug, due to ‘likely benefits’ and a lack of adverse events having been reported.
Nirmatrelvir-ritonavir was first recommended by WHO in April 2022. WHO strongly recommends its use in mild or moderate COVID-19 patients who are at high-risk of hospitalization. In December 2022, the first generic producer of the drug was prequalified by WHO.
WHO also reviewed the evidence on two other medicines, sotrovimab and casirivimab-imdevimab, and maintains strong recommendations against their use for treating COVID-19. These monoclonal antibody medicines lack or have diminished activity against the current circulating virus variants.
There are currently 6 proven treatment options for patients with COVID-19, three that prevent hospitalisation in high-risk persons and three that save lives in those with severe or critical disease. Except for corticosteroids, access to other drugs remains unsatisfactory globally.
