Corona viruses are a group of viruses that can cause a range of symptoms including a runny nose, cough, sore throat and fever. Some are mild, such as the common cold, while others are more likely to lead to pneumonia.

They're usually spread through direct contact with an infected person. The infection is typically spread from one person to another via respiratory droplets produced during coughing and sneezing. Time from exposure to onset of symptoms is generally between two and 14 days, with an average of five days.

The standard method of diagnosis is by reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab or throat swab. The infection can also be diagnosed from a combination of symptoms, risk factors and a chest CT scan showing features of pneumonia.

Containment Strategies Successful to Date

  1. Travel restrictions
  2. Airport entry screening
  3. Customs and Border Protection (CBP) and CDC screen passengers  returning from China for symptoms, travel to Hubei province and  close contacts
  4. Movement restrictions and monitoring of people at high and medium risk
  5. Lab testing of symptomatic individuals at increased risk
  6. The goal of containment strategies is to rapidly identify new cases and limit secondary transmission to persons who are under isolation so exposures are limited and transmission chains are  suspended
  7. Public education
  8. Healthcare providers and healthcare facility education
  9. Practice good hygiene
  10. Be careful with meetings and travel
  11. Avoid crowding
  12. Households with sick family members

    • Give sick members their own room if possible, and keep the door closed
    • Have only one family member care for them
    • Consider providing additional protections or more intensive care for household members over 65 years old or with underlying conditions
  13. Households with vulnerable seniors or those with significant underlying conditions
    • Significant underlying conditions include heart, lung, kidney disease; diabetes;  and conditions that suppress the immune system
    • Have the healthy people in the household conduct themselves as if they were a significant risk to the person with underlying conditions. For example, wash hands frequently before interacting with the person, such as by feeding or caring for the person
    • If possible, provide a protected space for vulnerable household members
    • Ensure all utensils and surfaces are cleaned regularly
