The virus that causes the coronavirus has killed more than 8 million people and left more than 11 million in need of hospital care, but it could take decades for scientists to identify its causes and treatments.
Scientists and public health officials have spent months in the laboratory searching for the virus and its genetic makeup that can be used to identify the virus’ original source and its potential causes, which can then be used as drugs.
The team has been able to identify and isolate the virus’s RNA in the form of a fragment of the virus known as a splice site, but the researchers also need to be able to use it to predict the exact sequence of the splice sites, which are key to the disease’s ability to spread.
In a statement on Tuesday, Dr. Craig Murray, director of the National Institute of Allergy and Infectious Diseases (NIAID), said that it was still unclear how much the virus was able to infect people and that he hoped that by the end of the year it would be possible to identify when it first appeared.
“We know that it can infect very quickly,” he said.
“But we need to get to the point where we know that we have the sequence of where the virus is, how quickly it can be spread and then the time that we can stop the virus from spreading.”
The virus causes symptoms in a variety of ways, but in a person who has the virus in the bloodstream, the body’s immune system kicks in and destroys the virus, usually within 24 hours of infection.
If the virus cannot be eliminated from the body within 24 to 48 hours, it can eventually cause severe disease.
People who have not yet had the virus can be infected with other strains of the coronovirus, which is spread by direct contact with blood, feces or vomit.
People can contract the virus through a blood transfusion or when their kidneys fail, or when they have a blood clot that blocks the blood supply to the brain.
A large proportion of the infected population has yet to be diagnosed.
About 3 million people are believed to be at high risk for developing the virus.
But experts said the disease could be curable if there is a concerted effort to protect people.
Dr. Murray said that, even with the best methods, the risk of spreading the virus to large numbers of people was very low, given the large number of people who are already being exposed to it.
And he said that scientists are hopeful that by 2020, they will be able make progress in identifying a vaccine that could protect against the virus while also providing an effective way to stop it from spreading.
But he said there is still a long way to go to find a vaccine for this particular virus, and there were some areas of the world where it is still hard to vaccinate people.
The world has been dealing with pandemic-related diseases since 1918, when the Black Death killed an estimated 20 million people worldwide.
An estimated 60 million people died in Europe and the United States in the following years, and another 9 million died in Asia and Africa.
During the pandemic, many nations were left to deal with the consequences of the disease, with many of the diseases treated as pandemic emergencies.
Many countries, including Japan and the U.K., declared pandemic illnesses, or emergency medical conditions, and others imposed restrictions on public activities.
Most countries have now ended pandemic emergency-related conditions, but there are still more than 20 countries in Africa and Asia with the virus that are still not able to provide adequate medical services, Dr Murray said.
One of the most serious problems, he said, is that there are many different strains of coronaviruses, and some strains of them may have the same mutations that allow them to spread from person to person.
While researchers have identified the virus as the source of the current pandemic in some countries, it is difficult to say if the virus has originated in Africa, Dr Paul Kostin, director general of the World Health Organization, said in a statement.
We have been unable to find any direct evidence that a virus originating in Africa or Asia has caused the pandemics, or that there is any link between the current outbreak and the pandems from Africa and Southeast Asia, he added.
Experts said that the virus may have begun its spread in countries that have seen little or no recent outbreak of the pandics, and that its spread is possible because of the rapid pace of travel and the spread from country to country.
Some people have not been exposed to the virus at all, and the most likely scenario is that this virus is present in a population that is already susceptible, said Dr. James Kuzma, a professor of immunology at the University of Michigan and the chairman of the American Academy of Allergies and Infections.
Because the virus lives in the environment, we are seeing an increase in
