For those of you who have it just now, CPC mouthwash and antiviral nasal spray (eg Boots Dual Defence) may help reduce your viral load and help you clear it faster if you can get some delivered. They can be used preventatively too.
Ventilation and masks in communal areas (ideally FFP2) can help stop spread to family members
A pulse oximeter and thermometer may be useful to monitor your symptoms
Be careful once you're better as you can catch it again quickly (shortest recorded time is 16 days for a reinfection) and covid can also knock your immune system, there's other bugs doing the rounds too so try to avoid them if you can.
FFP2 masks, antiviral nasal spray and good ventilation are also the best things you can do to avoid it if you're currently well.
We need government to put HEPA filters in classrooms and for employers to invest in ventilation/filtration systems really to tackle this longer term. Oh, and for people to wear masks at least if they have cold symptoms or if they know they're a contact if someone who is covid positive, too many people out there hacking up a lung who aren't polite enough to wear a mask sadly.
Really hope everyone who is poorly at the moment feels better soon.
