CORONA VIRUS FROM CHINA

The first appearance of the corona virus occurs on 31st December 2019 when it makes its first appearance in Wuhan, metropolis of 11 million people, the capital of the province of Hubei, giving way to that which in a few weeks has become an epidemic capable of spreading also out of China. Immediately a group of scientists of the Johns Hopkins University (in Maryland, USA) developed a map to display and trace the cases reported in such a way as to have a clear idea of what is happening at this time in China and in the rest of the world.

After almost a month and exactly on the 27th January 2020 the W.H.O. has admitted that the overall risk arising from Chinese coronavirus is “high”, by correcting the previous reports in which it “wrongly” spoke of the level as “moderate”, as clarified in a note from the spokesperson Fadela Chaib. There is also the risk that we will soon be able to speak of “international health emergency”, also stressed the Health Minister Roberto Speranza. The new virus, he added, “is classified as type B (as SARS and Polio) as a danger, but is in fact managed as one of class A, like cholera and plague”.

BUT WHAT ARE THE SYMPTOMS OF THE CORONA VIRUS?

The coronavirus are so called for their “crown” shape affecting both humans and animals. The Chinese experts in the case of 2019-n-CoV said that it is possible for man-to-man infection or from human/animal.

The first time the virus was identified on people who had attended the public market of Wuhan, where in addition to fish there are other live animals present.  In China the markets sell many species of animals both live and dead and not always in the best hygienic conditions. The first patient was reported to the World Health Organization and on the 9th January Chinese experts published part of the genomic sequence. The symptoms are similar to those of pneumonia and today there are over 100 dead and 6000 infected, not only in China. The contagion in fact has already touched other Asian countries such as Japan, Hong Kong and Singapore, but also European countries such as Italy and Germany where the first patient was recognized as affected by the corona virus, and even the United States already counted several cases. Some airports have already activated safety procedures as scanners for fever and in some countries flights to and from China have been interrupted.

Symptoms of corona virus:

The most common symptoms of an infection by coronavirus in humans include fever, cough, breathing difficulties. In the most serious cases, the infection can cause pneumonia, severe acute respiratory syndrome, renal insufficiency and even death. In particular:

  • The common human coronavirus usually cause diseases of the upper respiratory tract from slight to moderate, such as the common cold, that lasts for a short period of time. Symptoms may include:
    • Runny nose
    • Headache
    • Cough
    • Sore throat
    • Fever
    • A general feeling of malaise.

The human coronavirus can sometimes cause diseases of the lower respiratory tract, such as pneumonia or bronchitis. This is most common in people with pre-existing chronic pathologies such as cardio-vascular and/or respiratory, and subjects with a weakened immune system, in infants and the elderly.

  • Other human coronavirus that have evolved, such as for example Mers-VOC and SARS-CoV, can cause serious symptoms. The symptoms of the respiratory syndrome of the Middle East usually include fever, cough and wheezing that often are progressing into pneumonia and about 3 or 4 out of 10 cases resulted lethal. The cases of MERS continue to occur mainly in the Arabian Peninsula. The symptoms of severe acute respiratory syndrome, for which no new cases have been registered since 2004 in any part of the world, included fever, chills and muscle pains that usually progressed into pneumonia.

Given the little specificity of common symptoms of infection by coronavirus it is possible to carry out laboratory tests on respiratory samples and/or serum especially in the case of serious illness. It is nonetheless important, in case the symptoms occur, to inform your doctor of any trips or recent contact with animals.
