Summary

Coronavirus (COVID-19) can "survive" on various surfaces from a few hours to several days. The dangerous pathogen belongs to the sheath viruses, which means that it will be annihilated when treated with cleaning agents. In the case of materials, the cleaning agents used should be combined with high temperatures.

Coronavirus - persistence time on objects

According to the WHO (World Health Organisation), the 'survival rate' of COVID-19 depends on factors such as:

type of material,
humidity,
temperature.

US researchers at the National Institute of Allergy and Infectious Diseases (NIAID) tested the persistence of COVID-19 in home and hospital settings. As the results show, the virus on plastic surfaces, for example, persists for up to seven hours. On stainless steel surfaces, the residence time is more than 5 hours. The shortest residence time is on copper objects (46 minutes).

Disinfection of objects

For disinfection of objects and large surfaces (e.g. worktops, kitchen tables, tiles, etc.), it is sufficient to use ordinary detergents - the basic "breeding ground" for harmful microorganisms is a damp environment containing protein, fat and other impurities (ordinary detergent separates the fatty film from the objects). You can also use ozonisers and steam cleaners.

Important! Disinfection must be carried out regularly and with the precautions recommended by the manufacturer.

When disinfecting electronics (e.g. smartphone, computer, laptop), chemical-sensitive items and moisture, only use products designed for cleaning these types of items.

Important! Most germs persist on a smartphone (should be disinfected 2-3 times a day), a watch and jewellery.

Disinfection of clothing

When disinfecting clothes, simply wash them - the virus will not survive in hot water full of soap.

Important! Wash clothes on a regular basis and do not leave them in the laundry basket for days.

What should be disinfected most often?

The most frequently disinfected items should be:

kitchen (worktop, table, cupboard handles, fridge handle, cooker knobs, tap and sink).
rooms and hallways (light switches, handles, chair and armchair backs, handrails, electrical sockets).
bathroom (tap, cistern, washbasin, bath, shower cubicle).
bedroom (bed linen should be changed once a week).

Summary

The International Pharmaceutical Federation (FIP) has provided a list of disinfectants depending on the item that may have been contaminated. The list was compiled by the Chinese Pharmaceutical Association:

object surface - disinfectant containing chlorine (1000 mg/ l), chlorine dioxide (500 mg/ l), 75% alcohol,
hands - quick-drying hand disinfectant containing alcohol, disinfectant containing chlorine, hydrogen peroxide (hydrogen peroxide),
skin - iodine-based disinfectant 0.5%, hydrogen peroxide,
mucous membranes - iodine-based disinfectant 0.05%,
indoor air - peracetic acid, chlorine dioxide, hydrogen peroxide,
dirt - chlorine-based disinfectant (5000-20000 mg/l), disinfectant powder or absorbent bleaching powder,
textiles: clothing, bedding - chlorine-containing disinfectant (500 mg / l, ethylene oxide),
prescriptions - ethylene oxide.
