CoronaVirus symptoms and how to prevent COVID-19
Symptoms of coronavirus
According to Central Department of Health
Symptoms of coronavirus in humans are very similar to those of SARS and influenza. Therefore, it is so difficult to recognize this infection to medical professionals. The incubation period of the development of a new disease caused by a viral epidemic is on average 7 days, however, there are cases of the development of coronovirus infection in the period from 2 to 12 days. The longest incubation period, according to Chinese doctors, was 14 days.
This means that a person may already be infected with a coronavirus, but for another two weeks he may completely not feel this, external symptoms of the disease may also not appear.
Coronavirus survives for several hours on inert surfaces and several days in the aquatic environment.
Coronavirus symptoms in humans
Symptoms that have been seen in patients with a new type of coronovirus in China and other countries of the world:
fever (temporary increase in body temperature)
severe dry cough
diarrhea (digestive upset, diarrhea)
conjunctivitis (inflammation of the mucous membrane of the eyes)
disorders in the liver and kidneys
The picture of the development of the first symptoms of coronavirus in humans changes rapidly: the onset of the disease is accompanied by the manifestation of diarrhea (indigestion, loose stools), shortness of breath, and an increase in body temperature. Some patients exhibit inflammation of the mucous membrane of the transparent membrane of the eyes (conjunctivitis), covering the surface of the eyeball. Fever develops, body temperature rises sharply.
Further, a coronavirus infection can affect the lower respiratory tract, leading to severe pneumonia and sepsis, which can be fatal.
Coronavirus analysis reveals alarming data
Symptoms of infected people were also questioned by virologists in this study. In particular, they claim that fever does not appear to be systematic and does not occur in all infected people. The scientific article was posted on February 9 on the MedRxiv Sharing Server.
Another unpleasant fact, which was published by Chinese specialists in the field of infectious diseases, is that already during the incubation period of the virus, a person can become a source of spread of infection for other people.
An authoritative professor from Beijing, Nan-shan Zhong, said:
"I hope this epidemic ends in April, the biggest problem is that we don’t know why it is so contagious."
Closed spaces may increase the risk of infection.
Staying in an enclosed space for a long period of time can lead to infection - this is the conclusion made in the latest recommendations of the National Health Commission of China.
In terms of treatment and diagnosis of the new coronavirus, the commission confirmed that the virus was mainly transmitted through respiratory droplets of moisture and in close contact with infected people.
However, it was added that the content of the virus in the air contributes to the disease at high concentrations in the air - drops, small particles of moisture that a person exhales - in a relatively closed environment for a long period of time.
To reduce the risk of infection, it is necessary to regularly air the premises and carry out wet cleaning.
What is the difference between coronavirus and influenza virus?
These two types of virus are very difficult to distinguish at the initial stages of the development of the disease. But their difference is obvious: the influenza virus multiplies in the upper respiratory tract (nose, pharynx, larynx), and the coronavirus in the lower respiratory tract (larynx, trachea, bronchi, lungs). Therefore, pneumonia (pneumonia) occurs, from which people die.
