I don't know enough about treatment to comment on that, but for infection control the 3 pillars here are isolation, filtration, ventilation.</p><p>Isolating to stop yourself infecting others around you is key in this stage, if your symptoms don't require hospitalization. Be in a different room, close the door, use a draft excluder or staple a blanket around the door frame to reduce airflow.</p><p><a href="https://kolektiva.social/tags/CorsiRosenthal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CorsiRosenthal</span></a> <a href="https://kolektiva.social/tags/CRBox" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CRBox</span></a> is easy to make with box fan and HEPA filters and duck tape (if central air is common in your country) and does a great job filtering the air. You can calculate the air changes per hour (ACH) but realistically just do the best you can and hope for the best. Keep it on whenever you can, especially during the acute phase.</p><p>Outside air has negligible viral load, so any airflow from outside to inside, or a cross breeze between two windows, is going to improve that ACH number</p>
