2. BABESIOSIS
• INTRODUCTION :
• BABESIOSIS IS A RARE INFECTIOUS DISEASE
CAUSED BY SINGLE-CELLED MICROORGANISMS
(PROTOZOA) BELONGING TO THE BABESIA
FAMILY. IT IS BELIEVED THAT THE BABESIA
PROTOZOA ARE USUALLY CARRIED AND
TRANSMITTED BY TICKS (VECTORS). BABESIOSIS
OCCURS PRIMARILY IN ANIMALS; HOWEVER, IN
RARE CASES, BABESIOSIS INFECTION MAY OCCUR
IN HUMANS. CERTAIN BABESIA SPECIES ARE
KNOWN TO CAUSE BABESIOSIS INFECTION IN
HUMANS (E.G., BABESIA MICROTI), AND THE DEER
TICK IS A KNOWN VECTOR.

3. CAUSES :
• HUMAN BABESIOSIS INFECTION MAY CAUSE FEVER,
CHILLS, HEADACHE, NAUSEA, VOMITING, AND/OR
MUSCLE ACHES (MYALGIA). SYMPTOMS MAY BE MILD
IN OTHERWISE HEALTHY PEOPLE; IN ADDITION, SOME
INFECTED INDIVIDUALS MAY EXHIBIT NO SYMPTOMS
(ASYMPTOMATIC). HOWEVER, A SEVERE FORM OF
BABESIOSIS, WHICH MAY BE LIFE-THREATENING IF
UNTREATED, MAY OCCUR IN INDIVIDUALS WHO HAVE
HAD THEIR SPLEENS REMOVED (SPLENECTOMIZED)
OR WHO HAVE AN IMPAIRED IMMUNE SYSTEM. A
DIFFERENT FORM OF BABESIOSIS HAS BEEN
REPORTED IN EUROPE THAT IS ASSOCIATED WITH A
MORE SEVERE EXPRESSION OF SYMPTOMS.
