Uit diverse onderzoeken die al decennia lang zijn uitgevoerd
Het RIVM baseert onder meer op dit onderzoek van 29 maart 2020 (specifiek gericht op het COVID 19 virus)

Modes of transmission of the COVID-19 virus
Respiratory infections can be transmitted through droplets of different sizes: when the droplet particles are >5-10 µm in diameter they are referred to as respiratory droplets, and when then are <5µm in diameter, they are referred to as droplet nuclei.1 According to current evidence, COVID-19 virus is primarily transmitted between people through respiratory droplets and contact routes
Droplet transmission occurs when a person is in in close contact (within 1 m) with someone who has respiratory symptoms (e.g., coughing or sneezing) and is therefore at risk of having his/her mucosae (mouth and nose) or conjunctiva (eyes) exposed to potentially infective respiratory droplets. Transmission may also occur through fomites in the immediate environment around the infected person.8 Therefore, transmission of the COVID-19 virus can occur by direct contact with infected people and indirect contact with surfaces in the immediate environment or with objects used on the infected person (e.g., stethoscope or thermometer).
Airborne transmission is different from droplet transmission as it refers to the presence of microbes within droplet nuclei, which are generally considered to be particles <5µm in diameter, can remain in the air for long periods of time and be transmitted to others over distances greater than 1 m.
In the context of COVID-19, airborne transmission may be possible in specific circumstances and settings in which procedures or support treatments that generate aerosols are performed; i.e., endotracheal intubation, bronchoscopy, open suctioning, administration of nebulized treatment, manual ventilation before intubation, turning the patient to the prone position, disconnecting the patient from the ventilator, non-invasive positive-pressure ventilation, tracheostomy, and cardiopulmonary resuscitation.
There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen.9 There have been no reports of faecal-oral transmission of the COVID-19 virus to date.
Virologen hebben het ook wel eens in lekentaal uitgelegd :
Het virus is weliswaar minuscuul klein.
Maar dat zijn airdroplets ook.
In airdroplets kunnen een aantal vi=rus exemlaren voorkomen.
Aerosols zijn veel kleiner dan droplets en bieden te weinig ruimte aan virus exemplaren daarop te zitten, laat staan een aantal virus exemplaren.
Er zal toch een redelijk aantal virus exemplaren het lichaam (neus) moeten binnenkomen om iemand succesvol te besmetten. Als er al virus exemplaren op een aerosol passen dan slechts een enkele.
Zolang Maurice de Hond niet met wetenschappelijk onderzoek kan aantonen dat virus exemplaren op aerosols aangetroffen zijn , dan is zijn hele verhaal over verspreiding met aerosols ongeloofwaardig.
