Coronavirus - What you should know about the Wuhan virus


Updated 19.02.2020

In December 2019, a new threat unknown to people has appeared in the world. An outbreak of the SARS-CoV-2 (earlier 2019-nCoV) virus, commonly known as coronavirus (the name comes from the group of viruses it originates from), began in Wuhan Province, causing COVID-19 disease.

According to the available information from Chinese authorities, it is most likely a virus derived from animals and spread to humans by food available on the market in Wuhan, made of snake and bat that may be carriers of the virus. However, this was undermined by the medical journal The Lancet basing on the cases of infected people who had not been in contact with this place.

Incubation period

COVID-19, a disease caused by coronavirus, is a form of upper respiratory tract infection. The incubation period - the period from infection until the first symptoms appear - lasts from one day to two weeks. This means that during this period the carrier may unknowingly infect others. The initial lack of symptoms is conducive to less caution and spread of the epidemic.

The first symptoms

At first, coronavirus infection is very similar to ordinary flu. It starts with fever, coughing and fatigue. For about a week, the disease does not cause special concern. Then, however, it accelerates rapidly and within a few days acute respiratory failure occurs. The patient must be hospitalized, has shallow breathing and requires respirator support. Chest x-rays indicate the typical features of viral pneumonia with diffuse bilateral infiltrates. People with weakened immunity system or health problems are at high risk group of dangerous and life-threatening complications.


Information provided by the media and sanitary services indicates that infection can occur through contact of the coronavirus with the mucous membrane of the respiratory tract and eyes. Initially reports claimed transmission of the virus only by contact, however, this was undermined by cases from Germany and Japan, where cases of drip infection were confirmed.

Ways of infection:

- touching the eyes, nose and mouth with hands that have been in contact with the infected surface
- by direct exposure to sneezing or coughing an infected person and getting into the respiratory tract and eyes
- airborne, i.e. contact with viruses spread in the air exhaled by infected people

Spread of the disease

The epidemic grow rapidly in China. At the moment, there are 75.282 diagnosed cases, however, it is assumed that the number of infected is much higher. 2.012 people have died so far. Outside China, coronavirus cases have been confirmed in 28 countries, including Germany in the Bavaria region. A total of 16 cases have been confirmed there. People traveling abroad and using air or rail connections are especially vulnerable. In some cases, COVID-19 can take a mild form and infected people can spread the disease without being aware of it.

An important threat during an epidemic is the failure of health care system, which, due to the number of patients, may have problems diagnosing coronavirus infection, as well as treating and hospitalizing people who need help.

    How to minimize risk of infection:

    - frequent hand washing / disinfection - hot water and alcohol easily kill the virus
    - avoiding touching your face with your hands in public places
    - wearing protective glasses - prescription glasses, sunglasses, no prescription glasses or even protective work glasses
    - respiratory tract protection - and the use of masks. The tighter the mask, the better fitted and the higher the filtration, the better

    Using any face shield like masks or filtration scarfs will reduce exposure and the risk of contracting a virus through:

    - airborne
    - direct exposure of people who sneeze and cough
    - indirect transmission through contaminated hands. It is also important to cover your eyes, wash your hands, and avoid touching your face in public.

    The use of filters with an efficiency level of at least N95 is a basic barrier. The best protection is provided by N99 filters, whose structure allows to stop the virus body from getting into the respiratory tract.

    Our offer includes filtration scarfs that combine a stylish look and ensure the highest standard of fit and tightness. The filtration system inside is equipped with N95 and N99 filters that will protect you against pollution and biological threats in the air.

    We advise you to observe media reports, avoid unnecessary travel by public means of communication (especially foreign), keep the aforementioned precautions despite the lack of symptoms and people infected in close surroundings.
