| | + | == Occasional, brief encounters == |
| | + | A one-time, brief encounter seems unlikely to transmit the disease, as many politicians who met with someone who had the coronavirus have not themselves contracted the disease. But a prolonged, repeated encounter with an infected person seems to have a high likelihood of contracting the disease. |
