It may not appear Coronavirus symptoms Since the beginning of the infection, health experts and scientists believe that the period before symptoms appeared is the most dangerous period for transmission of the infection to anyone else, and studies have shown that people may be contagious for about two days before symptoms of the Corona virus appear on them, according to the medical site, “Medical”.
“Right before symptoms appear, people are probably most contagious,” said Dr. Wernerbischoff, an infectious disease specialist at Wake Forest University in America.
“People who never show symptoms can also spread the infection, and this is a problem because many people will never seek testing unless they show symptoms or know they have been exposed,” he added.
But there is a more complex part to this question: What if someone learns that they have been exposed to the virus but tested negative for the virus – could it still be contagious?
Dr. Alan Wells of the University of Pittsburgh Medical Center of America said that a negative test within less than seven days after exposure to the virus “is a very weak indicator of whether you have a virus in your body or not.”

He added that some tests are less accurate than others, and you have to take into account the incubation period of the virus.
Wells continued, saying, “A negative test between seven and ten days of exposure to the virus is a better indicator, but even then some people may not test positive until later.”
“That is why if you have reliable exposure to a person infected with the virus, you should wear a mask and you must isolate yourself for more safety so that you do not infect others with the infection,” he said.
