COVID-19 disease, caused by a novel coronavirus, and the underlying health conditions of the infected person. Regardless of how many people become infected, scientists say there is no mortality rate for coronaviruses. Although most people are infected with a new coronvirus such as SARS-CoV-2, hospitalization is not necessary to fight the virus.
There is no evidence that COVID-19 is a pre-existing health burden, but Lipsitch says this is an open question. As far as the virus is concerned, he believes it is likely that children will become more seriously ill from infection than adults. The researchers do not know whether children were as susceptible to infection as adults or whether they could easily transmit the viruses to others. There is evidence that they are important for the spread of seasonal and pandemic flu, and some estimates suggest they make up as much as 20 percent of the population, according to the CDC.
The best way to determine the role of children in transmitting COVID-19, Lipsitch said, would be to conduct an accurate analysis - linked cases of coronavirus infections in children in the United States and other parts of the world - to determine how the virus spreads, whether children are infected, and whether they pass it on to others. According to experts, a key factor is how contagious the new virus is and the proportion of those infected who fall seriously ill. If coronaviruses become ubiquitous, the researchers also want to investigate how people develop immunity to the viruses after infection.
The new coronavirus belongs to a family of viruses that includes influenza virus as well as severe acute respiratory syndrome (SARS), which also occurred in China in 2002.
It spreads through droplets that are spread when an infected person coughs or sneezes, but can also be transmitted through contaminated surfaces. Doctors can detect the coronavirus in a person's blood, urine, saliva or other bodily fluids.
Rare strains that cause more serious illnesses are MERS-CoV, which causes diseases such as coronavirus pneumonia, pneumonia and acute respiratory infections.
In 2019, a new strain called SARS-CoV-2 was circulated, causing COVID-19. When new strains of the virus appear, they can cause diseases such as coronavirus pneumonia, pneumonia and acute respiratory infections. A novel coronavirus disease, Coronav Virus Disease 2019 (CVD-2019), is being observed in the United States and other countries.
This new viral disease is the result of an outbreak in Wuhan, China, which began in December 2019 and has now spread to most of the world.
There is currently no effective antiviral vaccine against this virus, although studies into its development are ongoing. Building on previous research on SARS-MERS, NIAID scientists and fellows are rapidly developing COVID-19, a diagnostic and therapeutic vaccine.
The project involves carrying out basic research to understand how the virus infects cells, causes disease and which interventions can prevent or stop the spread of the disease. NIAID researchers determine how viruses enter cells and cause diseases that begin within two months.
The term coronavirus covers all known viruses responsible for respiratory diseases, from the common cold to severe acute respiratory syndrome (SARS), which killed nearly 800 people during an epidemic in 2002-2003. The Centers for Disease Control and Prevention (CDC) has provided estimates for the number of cases and deaths from COVID-19 diseases in the United States. Currently, the total number of confirmed and probable cases is estimated at more than 2 million and the number of deaths is estimated at more than 115,000. According to the CDC, reported CO VID- 19 illnesses range from mild reported symptoms in some cases to milder symptoms for others, including diseases that lead to death.
People aged 65 and over and people with underlying health conditions seem to have the highest risk of developing serious illnesses. Those living in areas with high CO VID-19 exposure, such as the United States, Europe and Asia, have a higher risk of developing a serious disease.
The Centers for Disease Control and Prevention has found that patients with moderate to severe asthma may be at higher risk for more serious illnesses, but there is no published data to support this finding. Asthmatics are at risk of worse outcomes and are more likely to get the virus that causes COVID-19. A pandemic is frightening for people, and it is important to know that there is currently no evidence of increased rates of asthma infection.
So many of us wonder what people with asthma do with their medications, whether they are steroids, inhaled or oral. There is no evidence that steroids are contraindicated for COVID-19, but so many wonder if they do because their controllers are on steroids (inhale or orally). The Wuhan virus of 2019 (nCoV) belongs to the same virus family as the other two major strains of the CoV virus, NCOV-1 and NCoB.
SAR appeared in southern China in 2002 and apparently entered humans through aerosols made by infected civet cats and sold as food in rural markets. It spread rapidly, eventually killing 8,273 people and triggering global efforts to contain its spread, including in the disease-stricken city of Wuhan, China.
