Here’s what you need: WHO is warning against outdoor activities and the use of masks.
The agency says those who don’t want to be at risk should limit the amount of time they spend outdoors and keep a low profile.
It also said people should be aware of the symptoms and be prepared to show symptoms to family members and medical professionals.
It’s also encouraging people to take precautions such as wearing masks and taking the time to get home from work.
The CDC says people should avoid using their cell phones and other portable devices.
It says people can use their mobile devices for emergency communications and texting but they should not use them to communicate.
The virus has spread through the United States.
It has infected at least 15,000 people in the United Kingdom, at least 6,000 in Spain and at least 4,000 at a French hotel.
The outbreak has caused at least 1,200 deaths in the U.S. since March.
WHO says more than 4,700 people have died from the virus in Liberia, Sierra Leone and Guinea.
The WHO says it is “deeply concerned” about the spread of the virus.
“We are working closely with health systems to help contain the outbreak,” the agency said in a statement.
The U.N. health agency also has called for a global plan to contain the virus, which has already killed more than 3,800 people.
In its statement, the WHO said the world has been in a crisis for a long time.
“Today, it’s time to do something about it.
We must all act together,” the WHO added.
It urged people to avoid travel to countries where the virus has been reported, such as the U., Congo, Liberia and Nigeria.
In a statement, President Donald Trump said in an interview Tuesday that he was working with the Centers for Diseases Control and the U, but would not allow Americans to enter the United Nations until all of the countries are “under control.”
He also said he would make it a priority to find a way to stop the spread in the region.
“The U.K. has been a sanctuary, a beacon of hope, a safe haven for so many.
Now, we need to get back to that,” Trump said.
“If we do not act quickly, it will be a tragedy.
If we do act now, it can be catastrophic.”
He added that it was “essential” that the U to “get it together, and get it moving.”
