What do spike proteins do in COVID-19?
One of the key biological characteristics of SARS-CoV-2, as well as several other viruses, is the presence of spike proteins that allow these viruses to penetrate host cells and cause infection.
Is the COVID-19 virus an enveloped virus?
The COVID-19 virus is an enveloped virus, with a fragile outer membrane. Generally, enveloped viruses are less stable in the environment and are more susceptible to oxidants, such as chlorine.
When was the coronavirus family of viruses first discovered in humans?
Human coronaviruses were first identified in the mid-1960s.
Who is at risk for severe COVID-19?
COVID-19 is a new disease and CDC is learning more about it every day. Among adults, the risk for severe illness from COVID-19 increases with age, with older adults at highest risk. Severe illness means that the person with COVID-19 may require hospitalization, intensive care, or a ventilator to help them breathe, or they may even die. People of any age with certain underlying medical conditions (which now include pregnancy) are also at increased risk for severe illness from SARS-CoV-2 infection.
Can COVID-19 cause other neurological disorders?
In some people, response to the coronavirus has been shown to increase the risk of stroke, dementia, muscle and nerve damage, encephalitis, and vascular disorders. Some researchers think the unbalanced immune system caused by reacting to the coronavirus may lead to autoimmune diseases, but it’s too early to tell.
Can COVID-19 damage organs?
UCLA researchers are the first to create a version of COVID-19 in mice that shows how the disease damages organs other than the lungs. Using their model, the scientists discovered that the SARS-CoV-2 virus can shut down energy production in cells of the heart, kidneys, spleen and other organs.
Can COVID-19 cause major strokes?
Although rare, COVID-19 can cause seizures or major strokes. Muscular weakness, nerve injury, and pain syndromes are common in people who require intensive care during infections. There are also very rare reports of conditions that develop after SARS-CoV-2 infection, as they sometimes do with other types of infections.
How is COVID-19 similar to flu?
Both COVID-19 and flu can have varying degrees of signs and symptoms, ranging from no symptoms (asymptomatic) to severe symptoms. Common symptoms that COVID-19 and flu share include: Fever or feeling feverish/chills. Cough. Shortness of breath or difficulty breathing.
