General advice on covid-19

These general tips complement the general tips you can find at Folkhä

Sars-cov-2 is a virus where we get sick by inhaling aerosol, micro-tiny water droplets containing virus particles, from the exhaled air of an infected person. We know that such microdroplets can remain in the air indoors for several hours. Infection can also occur through droplet infection, slightly larger water droplets, if the infected person sneezes or coughs nearby. In addition, a few may have been infected by first touching a surface with a virus and then poking themselves in the face. If we get sick, we get the diagnosis covid-19. Some never notice that they are infected, others can become seriously ill and die from the infection.

Some studies indicate that the largest proportion of those who become ill have been infected via aerosol. We know that mouth guards prevent the spread of infection, especially if everyone wears mouth guards, that is, both those who are not infected and those who are, often without knowing it. If the mouthguard has an exhalation valve, it only protects the wearer and not the environment if the wearer is infected. WHO provides guidelines on how to sew your own mouthguard with three layers of fabric, one hydrophilic near the mouth, one in the middle and one hydrophobic along the outside. The hydrophilic layer absorbs your water drops as you exhale. The hydrophobic repels the water droplets that you risk inhaling from the air. Even a simple paper mouth guard is better than no mouth guard at all.

The spread of infection occurs in the home, at workplaces, on buses, trams, trains and metros, in shops and in bars.

To protect yourself from inhaling virus particles, do the following:

Be aware that indoors, virus particles can linger in the air for many hours. Indoors, you risk inhaling virus particles, especially in small, unventilated rooms, no matter how far away you are from spreading the virus. The more people who stay in the room and the longer you stay in a cramped environment, the greater the risk, of course. High volume of voice as in bars and discos or as in choral singing increases aerosol production and thus the risk of infection. In larger premises such as grocery stores, the distance to the infected person plays a role, the greater the distance the better. Frequent ventilation, preferably with cross strokes, is an effective way to eliminate aerosol. Ideally, windows should be kept open for as long as possible.

Outdoors, the risk of becoming infected is clearly lower and logically depends on, among other things, wind speed, humidity and temperature. Thus: Use mouth guards in all environments where virus particles can spread in the air. Remember that an infected person does not need to have any symptoms at all and this also applies to so-called "super spreaders". Anyone around you can be a super-spreader. Always wear a mouth guard in your workplace if you are in the same room as other people or enter a room where virus particles may remain in the air.

If you or those who live with you have become infected or are at risk of becoming infected, always use a mouth guard at home when you are in the same room. In particular, the infected person should use a mouth guard.

To care for others, you should do the following:

If you lose taste or smell, a common onset symptom of covid-19, stay home and isolate yourself for at least 14 days. If you have other symptoms (fever, cough, frequent and loose stools) stay home and isolate yourself for at least 14 days or until you are told that you are not infected with sars-cov-2 through testing. To wear a mouth guard is to show consideration.

If you are diagnosed with covid-19, help identify everyone you have been close to for three days before falling ill.

If someone in a household is diagnosed with covid-19, everyone in the household should stay at home (self-quarantine) for at least 7 days.
Wash hands frequently or use hand sanitizer.

If you get covid-19, then you might want to consider the following:

Man kan mäta sin syremättnad kontinuerligt. Vid covid-19 kan mycket låga syrenivåer bli följden utan  att man märker det. Mätare som sätts på fingret finns att köpa.

Consider some type of drug that counteracts clot formation. Consult your doctor.

Science Forum Covid-19

Science forum Covid-19 works extensively with information and information about the ongoing pandemic and related topics and areas. Our goals are to reduce morbidity and mortality in Covid-19, to reduce the chronic disease states of those who survive Covid-19. In the association, we have expertise in areas such as virology, biology, molecular biology, epidemiology, infectious diseases, lung diseases, mathematics, political science, psychology, ethics and risk research. The chairman of the association is Professor Emeritus Anders Vahlne, more information at
