Health, Health Guide, Physiology Topics, How i Know if i Have Corona

Coronavirus is still expanding and has been reached more than 1 000 000 cases and killed more than 51,578. Most of them in the USA, Spain, and Italy. A lot of studies are conducting in order to know more about this virus. Recently a study has been shown that the infected individuals with Coronavirus often suffer from symptoms in the gastrointestinal tract before any of the known symptoms of the respiratory system begin to appear.


A new descriptive study conducted by a group of experts and doctors in Wuhan, China, published by “Daily Health Post”, citing An American scientific journal specializing in diseases of the digestive system. According to the study of 204 patients with Covid-19, almost half of them experienced symptoms started in the digestive tract, then followed by respiratory symptoms.


The authors of the study note that “doctors must bear in mind that symptoms of the digestive system, such as diarrhea, maybe one of the early symptoms of Covid-19 disease, and that the indication of suspicion may need to be treated as one of the precursors that need to be calculated early in this cases awaiting respiratory symptoms “. Thus, we must understand that the symptoms of the digestive system are a major step towards the early diagnosis of infection.


Be aware that 29% of those with Covid-19 suffer from diarrhea, 84% loss of appetite, 0.8% suffer from vomiting, and 0.4% suffer from abdominal pain.

Where Do Viruses Come From

Health, Health Guide, Physiology Topics, Where Do Viruses Come From

Viruses outbreaks have devastated human populations through history. Viruses have probably been around since the first cells arose, or perhaps even before them. There is disagreement about the origin of the viruses among scientists. As well as there are many theories about the origin of viruses. One of the theories hypothesis for the origin of viruses states that some viruses may have evolved from pieces of DNA or RNA that “escaped” from the genome of cells. The escaped DNA could have come from plasmids (pieces of naked DNA that can move between cells) or from transposons (molecules of DNA that replicate and move around the cellular genomes to different positions). Called jumping genes by Barbara McClintock in 1950. Another theory is Protobiont Hypothesis: suggests that viruses may have evolved from complex molecules of protein.

To understand how to deal with epidemics or pandemic and eradicate them, we need first to understand how they spread. The likelihood of a virus (or any pathogen) spreading within a given population is tied to several biological traits but it also relates to other variables, including social variables such as the behavior of individuals: how they live, how they crowd in cities or hospitals, and how they travel. Furthermore, requires integration of ecological, epidemiological, social, cultural, and engineering components.


Viruses face a world always changing. Viruses need to be in conditions that are suited toward to the biochemical stability of their vision. Viruses need to be in an environment with the right pH, temperature, and moisture content tolerable to the virus. The environment must also be free of irritants that can destroy the virus. For example, UV radiation, alcohol, and reactive oxygen species can all be harmful to a virus.


Viruses cannot replicate outside of the cellular context. They need the cell machinery to make copies of themselves. Viruses can replicate in different tissues and cell types. Viruses are a liquid poison in the blood. During infection, viruses build complex and specialized intracellular structures associated with membranes taken from the reticulum. Inside these vesicles, viral genomes are transcribed, translated into proteins, and replicated. Viruses don’t breathe, eat, produce waste, or otherwise. They only need to enter a specific living cell or inject its DNA into a specific living cell to reproduce itself.

Covid-19 Loves blood type A and Stay Stuck in The Air

Health, Health Guide, Physiology Topics, Covid-19 Loves blood type A and Stay Stuck in The Air

Covid-19 an “enemy of mankind.” has turned into a global pandemic. Scientists are trying to understand the secret of corona’s rapid spread. Scientists from the USA discovered in a new study that the new Coronavirus could stay stuck in the air for three hours, and be able to cause infection. While another study conducted by Chinese researchers revealed that people who carry blood type (A) may be more vulnerable to infection with the Coronavirus. While A while the risk is lower for individuals with blood type O. It has been known that the high prevalence of blood type A and B exist in Asia. That could be why Covid-19 can be virulent there.


 Coronavirus victims in Italy on life support

The American study stated that the new Coronavirus has a tendency to remains alive and suspended in spray droplets in the atmosphere for three hours. The study was conducted by scientists from the National Institute of Health and Infectious Diseases of the American National Institute of Health, and the University of California, Los Angeles and Princeton, and published in the online journal “New England Journal of Medicine” on Tuesday. 


The American researchers found that the virus can survive and infectiously in mist flying in the air for several hours and on surfaces for several days. The study revealed that the virus, which is carried by the flying mist from coughing or sneezing, remains able to survive or infect people through the air for at least three hours. While on plastic and stainless steel, the new virus remained for more than three days. The virus could not survive for more than a day when it settled on paperboard, and on copper, the virus remained for four hours before its effect ended.


Chinese researchers found that the risk of contracting COVID-19 is significantly higher for people with blood type (A). A Meta-analysis of the pooled data showed that among the COVID-19 patients, the proportion of blood group A was significantly higher while the proportion of blood group O was significantly lower. This finding has made the researchers infer that blood type A is more vulnerable to COVID-19.

Coronavirus Spread are Depending on The Traditions

Health, Health Guide, psychology Topics, Coronavirus Spread are Depending on The Traditions

Coronavirus (Covid-19) is transmitted, like all other viruses that attack the respiratory system. The infection can be transmitted from an infected person to others in many forms, depending on the traditions in the communities. The most common form is the form of a spray. The infection happens when the infected person sneezes, coughs, or speaks near the other at a distance of less than one or two meters. That can also be transmitted through close contact without any action. That’s why we recommend social distancing. As in the Swedish social lifestyle, especially now during the pandemic time. The infection can happen also, when a person faces air droplets and then touching his nose, ear, or mouth. As well as during handshaking. That’s why we recommend for this reason the Japanese greetings.


Corona virus can be easily shared, during sharing food and personal tools. That’s why don’t share with other food dishes, drink cups, towels, and napkins. Thus, the best strategy to face Coronavirus is to eat in your own dish, follow the Swedish social lifestyle, and do the Japanese greetings. As well as avoid contact with people who have symptoms of respiratory disease.

Physical Activities Can Boost Your Immunity to Fight Coronavirus

Health, Sport guide, Sport facts, Physical Activities Can Boost Your Immunity to Fight Coronaviru

Physical activities are not only essential for overall health, but also for boosting the immunity to fight Coronavirus. Your immune system protects you from viruses, bacteria, and parasites. In order to boost your immunity, you should boost your physical fitness. White blood cells can be completely dormant without physical activity. Therefore, exercise enhances their movements by increasing blood flow from and to the full body. So that it can help the white blood cells to perform monitoring, research, and destruction tasks in all parts of the body.


Physically activities should be every day. We recommend outdoor activities. For at least 150 minutes a week of moderate aerobic exercise. Such as hiking, slow juggling, and cycling. That can be also combined with 20 minutes of vigorous activities such as running, fast swimming, or weightlifting.


Furthermore, exercising and eating well will have a potential effect on helping you sleep better. Which is a bonus, because the tired body is more susceptible to germs. In fact, a study last year found that lack of sleep impaired the ability of a type of lymphocyte called T cell to fight disease.

Coronavirus is Changing its Symptoms

Health, Health Guide, Physiology Topics, Coronavirus for the first time under microscope, Coronavirus is Changing it's Symptoms

Coronavirus is changing its symptoms from time to time. A team of doctors in Singapore revealed the results of a study. That there are new symptoms caused by the emerging coronavirus. Not the famous symptoms that international medical centers had talked about before. The results of that study, which revealed the diagnosis of dengue fever in some people with Coronavirus. Where their temperature rises and they complain of a rash and itching, without appearing of the symptoms of the known virus infection. Such as cold, wet cough, and sored throat.


Chinese scientists have found changes in the symptoms of the infection of Coronavirus from time to time. According to the results of a study published on the Social Science Research Network, specialists examined 89 patients in Wuhan, who were divided into two groups. Initially, there were 31 people who were infected from January 16 to January 22. In the second group: 58 people were hospitalized with symptoms of SK from January 23 to 29.


The results revealed that the symptoms of the disease in the first group of patients appeared as follows: high temperature, muscle pain, weakness, sputum, and a decrease in the number of lymphocytes, while the same symptoms appeared in the second group, but they were weak or absent. while all patients showed symptoms such as coughing, diarrhea, nausea, and heaviness in the chest.

Best Prevention Guide to Avoid Coronavirus

Health, Health Guide, Physiology Topics, Best Prevention Guide to Avoid Coronavirus

The best prevention guide to avoiding the new epidemic Coronavirus is through eating foods and taking vitamins that support the immune system. Eating leafy vegetables and fruits which provide your body with essential vitamins and minerals. Such as citrus fruits, and berries. Even you should take 30 milligrams of zinc daily, 200 milligrams of vitamin C twice daily, and 250 milligrams of beta-glucan daily, 2000 IU of vitamin D3.


We believe that the safest way to contain the outbreak or get rid of the virus is to stay at home with an open window. Also, avoid contact with others, especially with infected people. Avoid shaking hands. Buy your basic needs, which are sufficient for more than two weeks. Cook your food to a high degree and don’t eat raw food such as vegetables and fruits. Don’t use the refrigerator or don’t eat cold food. Wash your dishes well at high temperatures. Don’t mix with others. Don’t travel on buses, 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. Don’t touch your eyes, mouth, or nose before you wash your hands. Don’t be close to others. If you are ill, see a doctor sooner rather than later. Cough on your elbow, not your hands. So you do not spread germs. Get the influenza vaccine to avoid confusion with seasonal influenza and COVID-19 virus infection.

Corona patients Why some live and others die

Health, Health Guide, Physiology Topics, Corona patients Why some live and others die

COVID-19 has two types, one is more fierce than others. A study revealed that the Coruna virus developed into two different strains. One of which appears to be more aggressive than the other. The study was conducted by researchers at the College of Life Sciences. At Beijing University of China and the Pasteur Institute in Shanghai. The study showed, that the Coronavirus developed into two main strains, called the “S” and the “L” type.


It is currently estimated that the number of infections found in the new Corona “Covid-19” has exceeded globally by 106 thousand. Of whom about 3,600 people have died. While about 60 thousand have recovered. So what determines whether a corona patient will live or die with the virus?


Let’s start with the story from the beginning, and start with a recent study representing the analysis of 72,314 people who infected with the Corona in China, and published in the Journal of the American Medical Association. The study looked at death rates among corona patients with different categories. For patients aged 70 to 79 years, the death rate was 8% and for those, over 80 years the rate was 14.8%. Also, found that for patients without chronic diseases, cancers, or immune problems, less than 1% died. For corona patients who already had cancer, the death rate was 5.6%. For people with high blood pressure 6%. For people with chronic respiratory diseases, the death rate was 6.3%. For people with diabetics, the death rate was 7.3%. and 10.5% for those with cardiovascular disease.


The cause of death of some people with the new Coronavirus “Covid-19” is a mixture of many reasons, starts with damage to the lung as a result of the corona, through previous problems that already exist as a result of previous diseases that are exacerbated by the Coronavirus. In addition to the type of virus that a person was infected with.
