A virus that was first found in Africa a few decades ago is now making its way across the Pacific and the Atlantic.
The coronavirus is spreading like wildfire in Latin America, where at least 11 countries have reported cases.
That has prompted concerns about how the virus will spread and where it may infect Americans.
The World Health Organization has said it expects that “macaca” and “macacaca” will become the two main strains of the virus by the end of the year.
But that is still far from being a full picture.
There are still several cases reported in the United Kingdom, where there are still no confirmed cases.
The virus is also spreading rapidly across the globe, with more than 1,000 cases reported since July 4, according to the WHO.
In some countries, including Brazil, it has already surpassed 1,100 cases.
In the United Arab Emirates, the outbreak has reached 1,600 cases.
But experts say there are some big questions that are still unanswered.
The WHO is keeping a close eye on the spread of the coronaviruses, including whether it will spread through air travel and how the coronajet virus is able to evade detection.
So far, there are no confirmed deaths.
And the WHO has been monitoring the spread.
But, the agency says, it cannot be certain that the coronovirus will be the first to reach the United Sates and other countries.
For some, this is a new challenge.
Dr. Stephen Satterfield, a professor of medicine at Emory University School of Medicine, said the virus could have the ability to cause mass illness.
“If you can’t control it, how do you control it?” he said.
The latest information on coronavirosts comes from the Centers for Disease Control and Prevention, which reported Friday that the virus has spread across the country, including to the South and Midwest.
But experts say it is difficult to pinpoint exactly where the virus originated and how it is moving around.
The WHO reported Friday it was still trying to determine where the coronatavirus originated, saying that the latest reports indicate it is spreading through air traffic.
The virus can be transmitted by contact with bodily fluids from the sick or dying person, and people who do not have the virus do not necessarily have symptoms.
“We don’t know where this virus is going to be going to because it is circulating so widely,” said Dr. Eric Schimmel, the director of the Center for Infectious Disease Research and Policy at Vanderbilt University Medical Center.
“It is also a good opportunity to start a conversation on the transmission of coronavira.”
The WHO is also monitoring the coronavalent vaccine, which has been administered to a handful of countries.
But its effectiveness has not been proven in people, Dr. Schimmels said.
