Among the characteristics of Covid-19 is its volatility, as confirmed by doctors. “When we get the flu, we go to bed for a few days and then we get better every day. In the case of the new virus, patients feel better one day, then relapse the next day. It is very strange. I haven’t seen anything Such during the 25 years of my practice in the profession. ”
A professional doctor in Paris says the patients “have the impression that it will not end.” She adds that it is important to alert patients to this so they can rest, even if they feel better.
Another distinguishing sign is that symptoms of the disease develop somewhat gradually, unlike the flu, for example, all of which suddenly appear. Symptoms usually last for two weeks or more, sometimes less. The patient may relapse a second time.
Sudden loss of smell or the ability to distinguish odors is a sign recently monitored that was not listed as a distinct symptom of the first victims in China.
During the past two weeks, ENT doctors have noticed that many of those who examined them only suffer from this symptom, without their nose clenched. “It just seemed strange,” says doctor Alain Coret, ENT specialist at the Rothschild Foundation Hospital in Paris. He and Dr. Dominic Salmon of Hotel Dieu Hospital had examined Covid-19 tests in about 60 patients who had lost their sense of smell and it was found that 90 percent of them were carrying it.
The loss of the sense of smell appears to be a pathogen, that is, a clinical sign that can in itself determine the diagnosis. At this point, it is the only specific symptom of the emerging coronavirus. Doctor Corré, who alerted the emergency center in his region, of this new syndrome, “In the current context, if you suffer from a loss of sense of smell and your nose is not blocked, this means that you are carrying the virus, and you do not need to undergo the test.”
Hence, the patient must isolate himself so that he does not transmit the virus to others. But this symptom by itself is not dangerous, and it often occurs in the first days of illness.
The SARS-Cove-2 virus is attracted to the nerves, when it enters the nose, instead of attacking the mucous membrane just as the usual nasal viruses do, it attacks the olfactory nerve and disrupts odor molecules, as Doctor Corrier explains. The injury is most likely local.
Since 90 percent of what we eat is related to the smell, people who have lost their sense of smell complain of losing their ability to taste food. But the loss of taste alone has not been described among the symptoms of the disease yet.
Patients often talk about their weakness. “I always hear the same thing, the patients are exhausted, they walk three steps and then they need to lie down again,” says Dr. Butte. Often this is accompanied by a headache, not necessarily associated with a fever.
SARS Cove-2 virus can cause volatile episodes of fever and usually slightly weaker than that of other viral syndromes. Many also complain of body aches, such as those that usually accompany viral infection, but are often more painful and localized.
Another sign of the disease is a dry cough, which is sometimes accompanied by a sore throat and a runny nose.
Some patients experience diarrhea and rarely feel nauseous. But, says Dr. Butte, “these symptoms alone are not enough to diagnose the disease.”
When the virus infects the lungs, patients experience various pain. Most patients reported feeling “locked” in the lungs. Others have expressed fear that they will no longer be able to breathe, and doctors say that “this could be exacerbated by anxiety, especially among those in isolation.”
The infection becomes disturbing when “patients breathe faster than usual,” says Bute, who asked her patients to call the emergency service as soon as they feel short of breath.
The tragedy with this virus is that it infects unprepared people
The patient’s condition can worsen suddenly between the seventh and fourteenth days, and he suffers from inflammation in the lungs, which appear in the x-ray with specific symptoms. Pauline, a Paris-based hospital physician, explains that “it is almost possible to know from the CT image that the patient has Covid-19.” She notes that most hospital patients have “a clinical condition that is hard to believe, because they do not suffocate while their blood oxygen level is at a catastrophic level.” “When things get worse, it happens suddenly.” Then we talk about severe acute respiratory distress which is a syndrome that has been observed in SARS patients and, to a lesser extent, influenza patients.
When the patient is placed in resuscitation, the respirator can raise the level of oxygen and improve the patient’s condition, but his condition can also deteriorate to death, without knowing the cause. “Most likely, a viral infection takes over the immune system,” she says. “It is a viral infection, as we rarely find secondary bacterial infections.” And she concludes that “the tragedy with this virus is that it infects people who are not prepared for it and ready to accept it 100 percent,” because the human immune system has not encountered it before.
However, the vast majority of Covid-19 cases are not serious, or they may pass unnoticed.
