从肯尼亚马萨兰93头产仔牛羚的胎膜或胎液样本中未分离到恶性卡他热病毒。恶性卡他热病毒无细胞株在野外条件下暴露于阳光下可迅速灭活，中午每小时至少损失3.0log10单位/25微升。研究表明，角马胎膜和胎液可作为牧场的视觉标记，在角马幼崽的眼鼻分泌物中受到恶性卡他热病毒的特别严重污染。每天早上晚一到两个小时开始放牧牛可能是一种有用的措施，可以帮助保护牛在被迫与产仔角马共享牧场的地区免受恶性卡他热的侵袭。
Malignant catarrhal fever virus was not isolated from samples of fetal membranes or fluid collected from 93 calving wildebeest (Connochaetes taurinus) in Kenya Maasailand. Cell-free strains of malignant catarrhal fever virus were very rapidly inactivated when exposed to the sun under field conditions, at least 3.0 log10 units/25 microliter being lost per hour at midday. It is suggested that wildebeest fetal membranes and fluids act as visual markers for areas of pasture which are particularly heavily contaminated with malignant catarrhal fever virus in oculonasal secretions of wildebeest calves. It is possible that starting to graze cattle one to two hours later each morning may be a useful measure for helping to protect cattle from malignant catarrhal fever in areas where they are forced to share pastures with calving wildebeest.
