covid-19 coronavirus
inspired by Guillermo Barrera Reyes
Coronaviruses (CoV) are a broad family of viruses that can cause a variety of conditions, from the common cold to more serious illnesses, such as the coronavirus that causes Middle East respiratory syndrome (MERS-CoV) and the one that causes respiratory syndrome. acute severe (SARS-CoV). A new coronavirus is a new strain of coronavirus that has not been found before in humans.
Coronaviruses can be passed from animals to people (zoonotic transmission). According to exhaustive studies in this regard, we know that SARS-CoV was transmitted from the civet to humans and that transmission of MERS-CoV from the dromedary to humans has occurred. Furthermore, it is known that there are other coronaviruses circulating among animals, which have not yet infected humans.
These infections are usually associated with fever and respiratory symptoms (cough and dyspnea or shortness of breath). In the most severe cases, they can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.
The usual recommendations for not spreading the infection are good hand and respiratory hygiene (covering your mouth and nose when coughing and sneezing) and the complete cooking of meat and eggs. Also, close contact with anyone who shows signs of respiratory distress, such as coughing or sneezing, should be avoided. Guillermo Barrera Lara, Guillermo Barrera
Care
The usual recommendations for not spreading the infection are good hand and respiratory hygiene (covering your mouth and nose when coughing and sneezing) and the complete cooking of meat and eggs. Also, close contact with anyone who shows signs of respiratory distress, such as coughing or sneezing, should be avoided.
Symptoms
Coronavirus infections can cause mild to moderate cases of acute respiratory infection similar to the common cold and the flu.
The most frequent signs and symptoms of COVID-19 infection are:
High fever (greater than 38 degrees)
Dry cough (no phlegm)
Loss of sense of smell and taste
Lack of appetite
Muscle pains
Fatigue
Headache
Sore throat
Persistent chills
Not all of the above symptoms may be present. Combinations of these symptoms can occur.

Coronavirus News Giving Hope
05/22/20 Remdesivir is the only drug tested for covid-19 so far. But it has some limitations ...
The researchers published this May 22 the data that led the federal government to recommend the use of the antiviral drug remdesivir in very sick patients with coronavirus, but they say that the drug alone will not be enough to help patients.
The data, published in the New England Journal of Medicine, shows that the drug shortened the course of the disease from an average of 15 days to about 11 days.
"The preliminary results of this trial suggest that a 10-day remdesivir treatment was superior to placebo in treating inpatients with covid-19," the researchers wrote. But it was not a cure and it did not act quickly.
"These preliminary findings support the use of remdesivir for patients who are hospitalized with covid-19 and require supplemental oxygen therapy," the researchers wrote, led by a team from the National Institute of Allergy and Infectious Diseases.
"However, given the high mortality despite the use of remdesivir, it is clear that treatment with an antiviral medication alone is probably not sufficient," they added. "Future strategies should evaluate antiviral agents in combination with other therapeutic approaches or combinations of antiviral agents to continue to improve outcomes for covid-19 patients."

20/07/20 La vacuna de Oxford es segura e induce una reacción inmune temprana
El 20 de julio se conocieron los resultados preliminares de un ensayo de fase 1/2 de una vacuna contra el coronavirus desarrollado por la Universidad de Oxford. Según un comunicado de la revista médica The Lancet, los resultados preliminares sugieren que es seguro e induce una respuesta inmune. La vacuna provocó una respuesta de anticuerpos dentro de los 28 días y una respuesta de células T dentro de los 14 días.
“El sistema inmunitario tiene dos formas de encontrar y atacar a los patógenos: las respuestas de anticuerpos y de células T. Esta vacuna tiene la intención de inducir ambos, por lo que puede atacar al virus cuando está circulando en el cuerpo, así como atacar a las células infectadas”, dijo en un comunicado el profesor Andrew Pollard, profesor principal de la Universidad de Oxford, autor principal del estudio.guillermo barrera lara, Guillermo barrera
07/21/20 Will it be ready soon?
AstraZeneca said on July 21 at a hearing in the United States Congress that it is on track to have a possible vaccine ready by September . However, hours later, the head of Britain's vaccine task force warned that a possible covid-19 vaccine is unlikely to be widely available before 2021. Meanwhile, other company executives said they are targeting achieve this in early 2021.
Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said he is confident that one of the vaccine candidates will prove to be safe and effective by the first quarter of 2021.
"In early 2021, we expect to have a couple of hundred million doses," Fauci said.
Dr. Francis Collins, director of the National Institutes of Health, made a similar forecast: "If all goes well, up to 100 million doses may be possible in early 2021."
But many doctors say that getting an effective vaccine by January is a very ambitious goal.
"Everything will have to be incredibly perfect if that is to happen," said Dr. Larry Corey, an expert in virology, immunology and vaccine development. Guillermo Barrera Lara, Guillermo Barrera
07/20/20 Oxford vaccine is safe and induces an early immune reaction
Preliminary results of a phase 1/2 trial of a coronavirus vaccine developed by the University of Oxford were released on July 20. According to a statement in the medical journal The Lancet, preliminary results suggest that it is safe and induces an immune response. The vaccine elicited an antibody response within 28 days and a T cell response within 14 days.
"The immune system has two ways to find and attack pathogens: antibody and T-cell responses. This vaccine is intended to induce both, so it can attack the virus when it is circulating in the body, as well as attack infected cells, ”Professor Andrew Pollard, a senior professor at the University of Oxford, lead author of the study, said in a statement.
