Brief summary describing the background
and objectives of the trial
|
Control measures against COVID-19 in higher income countries have focused on physical distancing and lockdowns which have had success in reducing population transmission. However, in lower resourced countries with populations that live day by day, lockdown is unsustainable. Other measures to reduce transmission will need to be considered. Several therapies improve individual patient clinical outcomes through a variety of effects including inhibiting viral replication. By doing so, therapies may also reduce transmission. SARS-CoV-2 binds to ACE2 receptors in the upper and lower respiratory tract and cases can be very infectious. The basic reproduction number (Ro) of SARS-CoV-2 has been estimated as between 2-5 in data from high intensity outbreak zones , higher than influenza for instance (Ro 1.3) possibly because of pre-symptomatic transmission, high viral load in upper respiratory tract and possibly prolonged shedding , as well as an immunologically naive population. To date, COVID-19 has not been reported as frequently as feared in Africa, suggesting that the Ro may be currently lower than reported in outbreak zones. Reasons for this are not clear since other respiratory viruses such as influenza seem to have as high burden in the African region as elsewhere. Drug therapy of COVID-19 patients with mild/moderate disease, may prevent progression to severe disease, but may also reduce the viral load in the upper respiratory tract, the duration of symptoms and the duration of virus shedding. In turn, this would be expected to reduce transmission to contacts. Understanding risks for household transmission and role of drugs with antiviral activity in reducing this burden will be very important in the near future, since if case numbers rise, mild/moderate cases may no longer be isolated in facilities, and these data therefore will feed directly into policy on how best to control COVID-19 in different settings. |
