There is no clear consensus among the maps experts on which parts of the United States are at greatest risk of a pandemic.
The maps are an important part of public health warnings for people, who often rely on maps to make decisions about how they travel.
The problem is that the maps are often built on outdated data, such as the one used by the Centers for Disease Control and Prevention (CDC).
But they also have important implications for policymaking.
There are currently about 4.4 million people in the United State, but a study from Johns Hopkins University found that a significant number of those people are clustered in areas with high levels of poverty and a lack of job opportunities.
Many of those areas are in the Northeast and Midwest.
In some places, like the Mid-Atlantic and West Coast, the map shows a large concentration of people living in poverty.
And many areas have no map showing their location.
The CDC uses the maps to inform its policymaking and health information.
For example, the agency has published maps of the most populated counties, and it has released data on the risk of pandemic-related death.
But the CDC has also issued its own maps of states, and the maps don’t always reflect what’s happening on the ground.
The map released in January by the Department of Homeland Security shows a map of the West Coast that shows areas that are at high risk of being hit by a pandemist.
It also shows areas where the CDC says that people are experiencing more frequent and severe symptoms of the virus.
Some map experts said that while the CDC maps can provide useful information, they’re often incomplete.
For instance, the maps show that many parts of California have not seen any cases of coronavirus in a decade, but that has not stopped the state from reporting it.
The data shows that the state has reported more than 1.5 million coronaviruses, but the data is based on the most recent date.
The state has not reported an increase in coronaviral cases since January.
And some map experts have argued that the CDC should release a new map showing areas that have seen an increase, because there are still clusters of people who have not developed symptoms and are therefore unlikely to develop the virus themselves.
While many maps do show the location of clusters of cases, they often do not provide information on how to avoid clusters, said Andrew Gelman, an epidemiologist at Johns Hopkins.
For that reason, he said, the CDC’s maps have not been a source of much public health advice.
“The maps should be a tool to guide public health, not a guide to health policy,” Gelman said.
The map of California is not the only map that shows clusters.
In December, the World Health Organization announced a map that showed the most-populated areas in Africa.
But that map also shows some areas that aren’t at all at high levels in terms of risk of an outbreak.
And some of the countries that the WHO calls the most at risk of spreading the virus are in regions with high poverty and no job opportunities for people.
The WHO map does show a cluster of five states in the U.S. that are near the extreme extremes of the map.
The worst-case scenario, if the disease were to spread, would reach all of those states.
