Noble Coronavirus (Covid-19)

Noble Coronavirus, Nearly one billion people on lockdown as deaths mount (https://www.thenational.ae/international), this now an Main Global Crisis Noble Corona Virus) is an infectious disease caused by a new virus.

The disease causes respiratory illness (like the flu) with symptoms such as a cough, fever,  and in more severe cases, difficulty breathing. You can protect yourself by washing your hands frequently, avoiding touching your face, and avoiding close contact (1 meter or 3 feet) with people who are unwell.

Causes

All coronaviruses sport spiky projections on their outer surfaces that resemble the points of a crown, or “corona” in Latin, according to the Centers for Disease Control and Prevention (CDC). Seven known coronaviruses can infect humans, including the novel coronavirus identified in 2019.

Noble CoronaVirus Disease (COVID-19)Beneath a coronavirus’s pronged exterior lies a round core shrouded in proteins and a “greasy” membrane, Jan Carette, an associate professor of microbiology and immunology at the Stanford University School of Medicine, told Live Science in an email. The core contains genetic material that the virus can inject into vulnerable cells to infect them. So-called spike proteins extend from within the core to the viral surface and allow the virus to “recognize and latch onto” specific cells in the body, Carette said.

“When the spike engages its receptor [on a host cell], a cascade is triggered, resulting in the merger of the virus with the cell,” he added. This merger allows the virus to release its genetic material and hijack the cell’s internal machinery. “Once this happens, the virus sheds its coat and turns the cell into a factory that starts churning out new viruses.”

HOW IT SPREADS
Coronavirus disease spreads primarily through contact with an infected person when they cough or sneeze. It also spreads when a person touches a surface or object that has the virus on it, then touches their eyes, nose, or mouth
People may be sick with the virus for 1 to 14 days before developing symptoms. The most common symptoms of coronavirus disease (COVID-19) are fever, tiredness, and dry cough. Most people (about 80%) recover from the disease without needing special treatment.
More rarely, the disease can be serious and even fatal. Older people, and people with other medical conditions (such as asthma, diabetes, or heart disease), may be more vulnerable to becoming severely ill.

People may experience:
  • cough
  • fever
  • tiredness
  • difficulty breathing (severe cases)
