1. Know about COVID-19 : Coronavirus Disease

Corona viruses are relatively large, round and enclosed in a shell. There are hundreds of species. Their genetic material can change as they multiply. This can facilitate their transmission from one species to another and suddenly make them dangerous for humans, although they have only infected animals so far. Corona viruses that can become a threat to humans are abbreviated as HCoV (human-pathogenic corona viruses).

The name corona is derived from the Latin word crown (under the electron microscope, the viruses have a crown-like appearance). Corona viruses were already discovered in the 1960s.

The new type of corona virus is capable of causing disease in humans. It appears that this virus first occurred in China and is transmitted from animal to human and from human to human.

Protection and Precautionary Measures of COVID-19
Star-CoV-2 :
The medically correct name for the Virus is “ Star-CoV-2”  
Covid-19 : The Medical term of the disease caused by this virus is “Covid-19”  

Transmission takes place via droplets –

– probably also via smear infection (e.g. sneezing), shaking hands and contaminated (soiled) surfaces.

The symptoms are similar to those of a flu infection:

fever, runny nose, cough, shortness of breath, muscle pain, fatigue. Occasionally this is accompanied by sputum, headache, coughing up blood and diarrhea. However, an infection can also be symptom-free.

The following complications may occur:

  • pneumonia,
  • multi-organ failure,
  • sepsis.

The incubation period,

i.e. the time it takes to show symptoms, is up to 14 days.

The disease progression is very variable:

from a harmless cold to fatal pneumonia. The course of the disease often depends on the overall condition of the infected person. If other diseases are already present or if the person is physically weakened, the risk of the disease progressing seriously or dying from it is greater.

According to the WHO (World Health Organisation) the risk of infection is high. On average, an infected person infects 2.7 other people. To protect yourself, you can use breathing protection, hand disinfection and keep your distance.

Treatment is symptomatic (improvement of respiration. reduction of fever, hydration, inhibition of inflammation).

At the first signs of a possible epidemic or pandemic, and generally at the onset of seasonal flu, the following precautionary measures will protect against possible infections.

2. Keep Your Distance for Corona Virus Alert

  • Generally , keep at least 1.5 meters away from coughing or sick persons.
  • Avoid large crowds
  • Avoid Handshakes.

3. Keep your hands out of your face for Corona Virus Alert

The hands should be kept away from the face. One should get into the habit of not touching the face with the hands. Touching the eyes can also lead to eye infections.

4. Hand Hygiene for Corona Virus Alert

The hands should be washed or even disinfected regularly! 80% of all infections are transmitted via the hands.

Hand hygiene is therefore of utmost importance:

  • before meals
  • after sneezing or coughing
  • after using the toilet
  • after contact with third parties
  • after contact with utensils that belong to other people

5.    Washing your hands for Corona Virus Alert

Moisten your hands under running. preferably warm water. Thoroughly distribute a sufficient amount of soap. Rub soap into the palms and backs of the hands, between the fingers. fingertips. fingernails, thumbs and wrists.

  • pH-neutral soap (to protect the protective acid mantle!)
  • if possible, use liquid soap rather than bars of soap outside your own premises
  • rinse and dry your hands thoroughly!
  • apply lotion to your hands regularly. Frequent washing and disinfecting of hands can affect the natural protective layer.
  • Wash towels at least at 60 degrees

6. Disinfecting your hands for Corona Virus Alert

Disinfection is preferable to hand washing. Washing hands too frequently can cause skin irritation. Soap rinses out skin lipids and damages the protective function of the skin. On average, nurses disinfect their hands 50 times a day.

  • it is best to use products containing ethanol for disinfection
  • ethanol is highly effective against viruses.
  • of all available disinfectants, it is the one that is best tolerated by the skin. It is suitable for hands and surfaces.
  • disinfectants containing ethanol, are available in spray bottles, dosing dispensers, hand gels or special cleaning cloths.
  • Please observe the exposure time: usually 30 to 60 seconds (see manufacturer’s instructions)
  • the use should not be overdone (e.g. regular disinfection of all household items, ethanol is toxic)
  • one to two bottles per household are sufficient
  • apply lotion to your hands regularly to replenish the lipids in the skin, especially if the products used do not contain moisturizing substances.

7. Disinfecting hands for Corona Virus Alert. How should I go about ?

  • moisten your hands completely with disinfectant (Caution: only use products that are suitable for hands.)
  • rub the palms of your hands together from all sides
  • rub the outside and the spaces between the fingers
  • rub the right and left thumb
  • rub the fingertips together in the opposite palm
  • continue for at least 30 to 60 seconds (observe the manufacturer’s instructions)

If no hand disinfectant is available, wash your hands as follows:

  • proper hand washing practices in everyday life provides sufficient protection against bacteria and viruses.
  • wash your hands for at least 30 seconds

8. Correct Coughing and Sneezing for Corona Virus Alert

  • keep at least a distance of one meter from other people when coughing or sneezing
  • preferably use a disposable handkerchief and immediately place it into a trash bin with a lid or dispose of in a sealable garbage bag
  • always wash your hands thoroughly after coughing or sneezing.
  • avoid shaking hands, or coughing or sneezing on someone
  • If no handkerchief is available to sneeze or cough in. sneeze and cough in the crook of your arm.

9. Breathing Masks for Corona Virus Alert

We recommend breathing masks for infectious diseases that are spread via the respiratory tract (droplet infection). In Germany, these were previously only recommended for sick people (to protect other people from infection) or for hospital staff coming into contact with sick people.

  • Only FFP2 or FFP 3 masks can provide reliable protection against viruses (the designations FFP 1/2/3 indicate the respective filter strength). The leakage rate is: FFP1 max. at 22%, FFP2 max. at 8%, FFP3 max. at 2%.
  • Caution! Masks are quickly sold out or are only provided for medical police, military etc. personnel.
  • masks made from gauze or fabric are not suitable in case of viruses.

How to wear a breathing mask

  • it must fit very closely to the face
  • it must reach over the chin
  • it must be tightly fitted to the bridge of the nose (press on the metal strip for a tight fit)
  • it must be replaced as soon as it becomes damp (breathing masks with exhalation filters become damp less quickly)
  • it must only be used once!
  • it must be disposed of in a separate garbage bag, which must be sealed as quickly as possible
  • since the mask can only protect when it fits tightly everywhere, bearded people should shave.

10. Disposable Gloves (non-sterile) for Corona Virus Alert

• Protective gloves protect against smear infection, e.g. from contaminated door handles etc.

• Protective gloves conforming European Standard EN 429 protect against microorganisms as well as against disinfectants (resistant to chemicals)

• Protective gloves conforming European Standard EN 455 (TRBA 250) protect against micro-organisms, but are not suitable for frequent contact with disinfectants

• When handling non-sterile disposable gloves from a box, it must be ensured that the remaining gloves do not get contaminated by contact.

Wearing disposable gloves is not a substitute for washing hands. Especially when gloves are changed or damaged, the hands can become contaminated. Additional disinfection is required.

11. Aprons and Protective Coats for Corona Virus Alert

In case of contact with a sick family member or fellow occupant. it is recommended to wear an apron or a protective coat to avoid contamination of your own clothing.

  • The protective coat must be changed at least once a day. It is best to put the coat into a garbage bag when leaving the room (wash, at least at 60 degrees Celsius, add laundry disinfectant if necessary).
  • Sleeveless aprons and gowns are the most practical and hygienic (no sleeves or cuffs, on which contamination with micro-organisms occurs frequently).
  • aprons without button strips offer an additional hygienic advantage
  • with bear arms, wear sleeveless coats or aprons only
