Eighty percent of the cases suffered from fever, of which body temperature was mostly 38°C-39°C. Physical findings in the chest indicated minimal abnormality. On red cell sedimentation rate 60% of the cases had middle-graded acceleration higher.
The cold-agglutination value was defined positive above 27, most of the cases showed 27 or 28 at their maximum value, most of which appeared in the 2nd-9th week. The pulmonary infiltration was observed in general in the lower lobes, Especially in the right lower lobe the infiltration was seen in the high rate of 44% and disappeared within the 2nd-9th week.
