* Studies are in ascending order as per the dose administered, with unknown doses at the end of the table. Within infection studies evaluating the same dose, references are in ascending order based on percentage infection. Dose shown as either 50% tissue culture infectious dose (TCID₅₀) or 50% hemadsorbing dose (HAD₅₀), except where indicated. † Indicates consumption through natural drinking or eating behaviors; ‡ dose shown in hemadsorbing units (HAU); ¶ unknown units used for quantification of dose. Key: MID, minimum infectious dose; ND, not determined.
