This death brings the number of deaths in Tunisia to 46, where early and strict confinement had been decreed on March 22.
Scientists focus on the transmission of viruses and bacteria through aerosols in the corona crisis. It could be as dangerous as droplet transfer. We clarify.
Compliance with distance rules, strict hygiene, sneezing and cough labels and wearing a face mask is intended to protect us against the corona virus. But scientists assume that not only droplet infection is the reason for virus transmission, but also aerosol transmission (source:). Properly clean
It's BIM time: New sources of contamination, surveys of nursing homes and municipal puzzles
"20 Minutes" compiles for you the information you should not miss this morning in your Newsletter morning (BIM) © AFP Of the eight new sources of contamination in the Grand Est, four are found in nursing homes. NEWS - "20 Minutes" compiles for you the information that you should not miss this morning in your Morning Information Bulletin (BIM) Did you miss the information of this early morning? We have put together a summary to help you see more clearly.
aerosols: what is it?
aerosols are invisible, tiny suspended particles in the air . They can be smaller than five micrometers, and therefore as small as fine dust. They arise wherever droplets are nebulized, for example when speaking and singing.
Aerosols could spread the corona virus through over distances of several meters.
Aerosol transmission: Interiors are particularly affected
The smaller a room, the more aerosols are distributed in the air and are inhaled by other people in the room. In particular, tight office spaces or small sports studios are at risk. The particles are better distributed and heavily diluted outdoors so that infection is less likely, but is still not excluded.
cannabis against corona: new study gives hope
© Getty Images health-cannabis-against-Corona.jpg cannabis against corona? It is nothing new that cannabis products have played an increasingly important role in medicine in recent years. Now the green crop could also be a potential helper in the fight against the Covid 19 pandemic. This is the prospect of a study by researchers in Alberta, Canada.
Especially during sporting activities emits a lot of oxygen and the dangerous aerosols. So if you run after another jogger, you inevitably breathe in the suspended particles of the predecessor.
The example of a service in Frankfurt shows how high the risk of infection through an aerosol transmission is . Although all safety measures (distance control, wearing a face mask, ...) have been kept here, many people have contracted the corona virus there.
How to protect yourself
The risk of infection via aerosols can be significantly reduced if you take some measures:Ventilate rooms frequently Ensure air circulation, e.g. with the help of fans Avoid many people in a room Train, hairdresser, ...) Wear a face mask
Wearing masks and observing the distance rule continue to be an important measure to protect against the coronavirus . A breathing mask made of fabric can significantly minimize the escaping air flow. However, aerosols are so fine that they pass through the masks. Nevertheless, the masks absorbent material probably also retains some of the aerosols .
