Corona Virus Symptoms, and How it Works

Health, Health Guide, Physiology Topics, Corona Virus Symptoms, and How it Works

Corona virus, the zoonotic virus which still terrifying the world. The virus transmitted through the respiratory system by close contact. Through coughing or sneezing or by touching an infected person or goods. The infection caused by the virus occurs mainly in winter and early spring. The virus is sensitive to heat. Ultraviolet rays. At 4 °C infectious viruses persist for up to 28 days. Viruses are more inactive at 20°C compared to four degrees. Viruses were also more rapidly inactive at 40 °C than 20 °C. Because of this characteristic, winter and early spring are the epidemic seasons of the virus disease

While In a recent WHO analysis of more than 55,000 cases of corona patients in China, found that most common symptoms were identified. Here is the percentage of people who had it:

1- Fever: 88%

2- Dry cough: 68%

3- Fatigue: 38% cough

4- phlegm or thick sputum of the lungs: 33%

5- Shortness of breath: 19%

6- Bone or joint pain: 15%

7- Sore throat: 14%

8- Headache: 14%

The growth of the virus is mostly in epithelial cells. It can also infect the liver, kidneys, heart, and eyes. It can also grow in other cell types (such as macrophages ). Coronaviruses so far, have about 15 different strains. Also, has been shown, that the viruses can infect a variety of mammals, birds, and humans. 


Coronavirus infections have been reported in the literature to produce the following clinical symptoms:

  1. Respiratory infections, including severe acute respiratory syndrome (SARS);
  2. Intestinal infections (occasional infants);
  3. Neurological symptoms (rarely).

Corona Virus Symptoms

Symptoms of infection with the virus take between two days to 14 days to appear. The symptoms vary between infected individuals. For instance, the symptoms were identified at the beginning of the outbreak as myalgia or fatigue for 44%, sputum production 28%, headache 8%. Fever 98%, hemoptysis 5%, Runny nose, and cough 76%. Dyspnea 55%. Discomfort, and pharyngitis 38%. The main symptoms are watery stools, Shortness of breath, and vomiting. In severe cases, bloody stools may occur. In rare cases, it also causes nervous system syndrome. Infection with the virus can lead to pneumonia, an infection in which the lungs swell and fill with fluid, and if this pneumonia is left without treatment it may be fatal. Images of the lungs in potential cases may be considered sufficient to diagnose the infection, instead of DNA checks.

How I protect myself from Corona Virus 

The best prevention strategy is to stay home, and don’t travel on buses, airplanes, or trains, and don’t sit in a public area or crawdad room. Wash hands frequently, with alcohol or soap. We also advise that a lack of personal hygiene is a major contributor to infection don’t eat at restaurants, wash your food, and cook it at a high degree. So if infected people were touching it, then the virus die in the high temperature. Don’t touch your eyes, mouth, or nose before you wash your hands. Don’t be close to others.

Covid-19 May Kill 65 Million People

Health, Health Guide, Physiology topics, Corona Virus May Kill 65 Million People

Corona virus arrived in Canada. Canada announced, on Sunday, that the public health authorities in Toronto received notification of the first confirmed case of coronavirus in a resident who recently returned from the Chinese city of Wuhan, according to the Canadian government said in a statement. Even the third injury in France has been reported. Besides, the French Ministry of Health confirmed, on Friday evening, the third injury on its soil. Moreover, doctors tested five patients in Scotland who were suspected of having a coronavirus. Their results have come back negative.


China has witnessed outbreaks of several diseases over the past years. Such as SARS and bird flu. As well as, currently is witnessing the spread of a new type of Coronavirus. Corona has no vaccine. This is confirmed by the Global Alliance for Vaccines and Immunization that developing a vaccine against the new Coronavirus. Furthermore, experts said that developing vaccines for corona may take at least a year.


The World Health Organization, earlier on 05/02/2020. Mentioned that the new Coronavirus, which has spread epidemic in China and appeared in at least 20 other countries. Has no treatment, while China and Thailand claim that have developed a treatment. Moreover, stated that 23,360 confirmed cases of Coronavirus have been registered in only China.

The number of injuries increased to about 23,360 in China



Scientists predicted that the Coronavirus may kill 65 million people. US health experts have predicted that the Coronavirus will kill tens of millions of people according to a report published in the British Daily Mail. The authorities have closed the city of Wuhan, which is the epicenter of the new coronavirus. While medical authorities around the world are seeking to prevent its spread. The spread of the epidemic virus depends on several factors. Including the severity of the disease, the ease of transmission between people, the population density, the availability of health services, and the nature of the place where the disease spread, and the movement of travelers.


“A global health threat”

There are fears that the infection will accelerate as hundreds of millions of Chinese travel at home and abroad during the Lunar New Year holidays, although many cancel their flights. Airports around the world have strengthened screening for travelers from China, although some health officials and experts question the utility of such checks.


With the development of transportation, there is no place in the world that is longer isolated. The virus may easily move to other places in the world with the movement of travelers and goods.
