| BERLIN — Some of the world's top experts tracking the spread of the coronavirus predict that in a matter of weeks, much of Europe could be facing a similar surge in cases that has locked down Italy, overwhelmed its hospitals in the north and brought the country of 60 million to a standstill. | BERLIN — Some of the world's top experts tracking the spread of the coronavirus predict that in a matter of weeks, much of Europe could be facing a similar surge in cases that has locked down Italy, overwhelmed its hospitals in the north and brought the country of 60 million to a standstill. |
| Mathematical models developed by epidemiologists to track the virus show a sharp trajectory of infections in Spain, Germany, France and Britain. Spain, which declared a state of emergency on Friday, showed particularly concerning exponential growth, some experts said. | |
| The modelers in Europe say a similar arc is likely in the United States, but anticipating the spread is made more difficult by the lack of widespread testing of suspected cases there. U.S. officials are working with 50 academic modeling groups across the country, The Washington Post reported, but no projections have been publicly released by the Centers for Disease Control and Prevention or the White House coronavirus task force. | The modelers in Europe say a similar arc is likely in the United States, but anticipating the spread is made more difficult by the lack of widespread testing of suspected cases there.

| Observations by epidemiologists show that if unchecked, the number of infections double approximately every five days, with infected individuals, on average, capable of passing the virus on to an average of about 2.5 people. | Observations by epidemiologists show that if unchecked, the number of infections double approximately every five days, with infected individuals, on average, capable of passing the virus on to an average of about 2.5 people. |

| Epidemiologists say that decisive action is required to change the rate of infection and “flatten the curve”. That reality appeared to sink in for some political leaders in the United States and Europe this week, as countries closed schools, encouraged working from home, banned large gatherings and imposed new travel restrictions. French Health Ministry Director General Jérôme Salomon said France must prepare itself for “the Italian scenario.” | |

| Still, some experts worry that governments aren’t doing enough to reduce rates of transmission so cases don’t soar exponentially and overwhelm health systems. A lack of urgency in previous weeks may have wasted valuable time, they say. | |
| Irish doctors on Friday warned that the country is “exactly 14 days behind Italy” in a letter to the British Medical Journal. They said that only stringent measures could head off a medical crisis like Italy’s and produce a more manageable outbreak like South Korea’s. | |
| At the beginning of an outbreak experts say viral spread can be contained by isolating individuals and tracing those in contact. But when cases begin to emerge where the infection source is unknown, as they have in parts of Europe and the United States, mass behavioral changes and social distancing appear to be the better strategy. | |
| Italy is one country that has had to accept quickly the need for drastic action. Just three weeks ago, it did not have much of a coronavirus problem. Now it has had more than 15,000 confirmed cases. Prime Minister Giuseppe Conte extended a lockdown on a handful of small villages to wide swaths across northern Italy on Sunday morning and then to the entire country on Monday night. On Wednesday, he went even further with the announcement of a shutdown of most commercial activity. | Italy is one country that has had to accept quickly the need for drastic action.

| Britain’s chief science adviser, Patrick Vallance, said Thursday that the United Kingdom had 600 confirmed cases, which he said means that 5,000 to 10,000 people there probably are infected. | Britain’s chief science adviser, Patrick Vallance, said Thursday that the United Kingdom had 600 confirmed cases, which he said means that 5,000 to 10,000 people there probably are infected. |
