Five questions about the coronavirus that scientists fail to answer. Despite the continuous and exhaustive work of scientists, the new outbreak of coronavirus continues to kill people and spread throughout the world because there are still questions that remain unanswered.
The outbreak of corona virus continues to spread, scientists continue to work to find the answers that could change the course of events.

Called 2019-nCoV, the new outbreak of coronavirus has infected almost 3,000 people, and has killed more than 80. According to official data, since the beginning of the outbreak in December 2019 in Wuhan city, central China, 51 people were discharged while there are 461 in serious condition.
In addition to mainland China, cases have been detected so far in Hong Kong, Macao, Taiwan, Thailand, Japan, South Korea, the United States, Canada, Vietnam, Singapore, Nepal, France, Australia and Malaysia.
The outbreak of corona virus continues to spread, scientists continue to work to find the answers that could change the course of events.


What is the origin of the coronavirus?

The authorities are working on the theory that the virus most likely originated in animals, and then spread to humans. A recent study indicated that snakes could be the source of the new outbreak of coronavirus. However, there are scientists who call into question this explanation and argue that it is actually certain types of mammals that transmit it.
What was determined was that the virus arose in Wuhan, since most of the first patients who were hospitalized were workers or customers of a wholesale market for shellfish, processed meats and live animals. Thoroughly knowing the epidemiology there will be key to fighting the virus.

What are the symptoms of coronavirus?

The ways in which the coronavirus can manifest are several and most resemble those of a cold; They may include fever, cough and dyspnea (shortness of breath). In the most severe cases, the infection can lead to pneumonia, renal failure and even death.
However, several atypical cases have recently been found during the diagnosis and treatment of new pneumonia. Such is the case of a 45-year-old male patient who went to the hospital for gastroenterological problems; He had diarrhea for three days. The man had no fever or respiratory symptoms.
When talking to the patient, the attending physician discovered that he had been in contact with a person infected with the new outbreak of coronavirus, so he decided to perform a CT scan of his chest and other tests. The results confirmed the presence of 2019-nCoV in his body.

In other cases, considered atypical, in addition to diarrhea, infected patients manifested other symptoms before having fever and cough, including:
  • mild appetite;
  • fatigue;
  • sickness;
  • vomiting
  • headache;
  • palpitations;
  • chest pain;
  • conjunctivitis;
  • mild pain in the limbs or lumbar muscles.


How is coronavirus virus spread?

This may be the most urgent question: determine how it spreads. The Chinese authorities have confirmed that some cases have been caused by transmission between humans, but it is still unclear whether this can happen commonly or these are exceptional cases.
"What is essential to understand is whether this happens at a pace and with a level of efficiency that would sustain a human epidemic," he told Nature Neil Ferguson, a mathematical epidemiologist at Imperial College London. The article explains that monitoring the rate of occurrence of new cases and the onset of symptoms in each of them should indicate to scientists the ease with which the virus can pass from one human being to another and if the outbreak has the potential to persist.

How lethal is the coronavirus?

The high rates of pneumonia among the first infected people caused many researchers to worry that the Wuhan virus was especially harmful. These concerns have decreased slightly, as more mild cases appear. However, the head of the National Health Commission of China, Ma Xiaowei, warned that the current situation indicates that "the virus is becoming increasingly contagious and requires further study."
Thus, the risks of eventual mutations are not entirely clear, nor is the danger involved for various age groups.


Can a drug be developed to treat coronavirus?

The Xinhua agency reported that the Chinese authorities have already begun the investigation for the development of a vaccine against the coronavirus.
Scientists are currently identifying the seed strain, said Xu Wenbo, head of the National Institute for the Control and Prevention of Viral Diseases, adding that they are also analyzing medications for pneumonia caused by the new coronavirus.
