•Serious chronic disease including any medically significant chronic pulmonary, cardiovascular, renal, neurological, psychiatric or metabolic disorder, as determined by medical history and physical examination. (Subjects suffering from seasonal allergies or asthma under inhalative treatment can be included).
•Acute disease at the time of enrolment. (Acute disease is defined as the presence of a moderate or severe illness with or without fever (defined as axillary temperature >=37.5°C)).
