Frequently Asked Questions

It is a novel virus named for the crownlike spikes that protrude from its surface. The coronavirus can infect both animals and people and can cause a range of respiratory illnesses from the common cold to lung lesions and pneumonia.
It seems to spread very easily from person to person, especially in homes, hospitals and other confined spaces. The pathogen can travel through the air, enveloped in tiny respiratory droplets that are produced when a sick person breathes, talks, coughs or sneezes.
The virus, which originated in Wuhan, China, has sickened more than 152,000 in at least 125 countries and more than 5,700 have died. The spread has slowed in China but is gaining speed in Europe and the United States. World Health Organization officials said the outbreak qualifies as a pandemic.
Symptoms, which can take between two to 14 days to appear, include fever, a dry cough, fatigue and difficulty breathing or shortness of breath. Milder cases may resemble the flu or a bad cold, but people may be able to pass on the virus even before they develop symptoms.
Washing your hands frequently is the most important thing you can do, along with staying at home when you’re sick and avoiding touching your face.
Keep a 30-day supply of essential medicines. Get a flu shot. Have essential household items on hand. Have a support system in place for elderly family members.
The State Department has issued a global Level 3 health advisory telling United States citizens to “reconsider travel” to all countries because of the worldwide effects of the coronavirus. This is the department’s second-highest advisory.
Several drugs are being tested, and some initial findings are expected soon. A vaccine to stop the spread is still at least a year away.
