On February 26, 2003, American businessman Johnny Chen, 48, was admitted to the French Hospital in Hanoi (Vietnam) after having visited the Chinese cities of Hong Kong and Shanghai. Chen's high fever, dry cough, and muscle and throat pain pointed to a severe case of the flu as a possible cause of his illness. However, respiratory distress and other complications appeared during the days after hospitalization. Although the businessman was flown back to Hong Kong for treatment, he could not overcome the infection and died on March 13. The nightmare had just begun. Since Chen's admission, about 40 people associated with the Vietnamese hospital have fallen ill, including the center's health team. The chest x-rays of those infected were similar to those of the American businessman. Panic was beginning to seep into the hearts of the healthcare workers, who understood that they were facing something very serious and extremely unusual.
Later, the Hanoi incident was linked to an unexplained outbreak of pneumonia in the southern Chinese province of Guangdong. This had begun in November 2002, in the city of Foshan. Scientific evidence AOL Email List indicated that the disease was caused by a new virus, SARS-CoV. This was the origin of the 2003 epidemic, which caused more than 8,000 infections in 26 countries. Although research suggests the cause was the virus's ability to spread from animals to people, the animal reservoir is still uncertain. One of the possibilities is that it was bats that transmitted the pathogen to other animals, such as civets, and these were the ones that transmitted it to humans. SARS-CoV is not the only one SARS-CoV belongs to the coronavirus gang, and has a significant number of companions. These are zoonotic viruses belonging to the Coronaviridae family and described more than fifty years ago. Its name comes from its morphology.
Which is reminiscent of the solar corona. Everything indicates that the first observations of the infective capacity of coronaviruses were made in 1933 by researchers Baudette and Hudson. They were the ones who observed a respiratory syndrome in chickens caused by an infectious agent. They later managed to transmit the lethal and devastating respiratory disease to embryos. Years later, the pathogen was identified as the Avian Infectious Bronchitis virus (IBV), an acute and highly contagious disease that affects chicken birds. Today, it remains one of the main causes of economic losses in the global poultry industry. As of today, we already know of 39 different species of coronavirus, 7 of which can infect humans. We also know by now that coronaviruses are enveloped, non-segmented viruses with single-stranded RNA genomes approximately 26 to 32 kilobases in size. The human coronavirus.
