In developing countries, every year about 70 million measles cases occur with 1.5 million deaths, over 200,000 children contract paralytic poliomyelitis, 50 million people get infected with viral B
hepatitis
causing over 1 million deaths, and several thousand people perish because of yellow fever according to WHO data. At the present time, there are 12 vaccines against viruses: vaccines against
German measles
and mumps in addition to the above. The universal immunization program (UIP) of WHO targets measles and polio. In 1989, a WHO resolution envisioned a 90% immunization coverage by the year 2000. Measles vaccination is recommended for children aged 9-23 months, since most children have maternal antibodies during the first 3-13 months of age. The Edmonston-Zagreb vaccine provided seroconversion of 92, 96, and 98% for 18 months vs. the 66, 76, and 91% rate of the Schwarz vaccine. In the US, measles incidence increased from 1497 cases in 1983 to 6382 cases in 1988 to over 14,000 cases in 1989, prompting second vaccination in children of school age. The highest incidence of polio was registered in Southeast Asia, although it declined from 1 case/100,000 population in 1975 to .5/100,000 in 1988. Oral poliomyelitis vaccine (OPV) provides protection: there is only 1 case/2.5 million vaccinations. Hepatitis B has infected over 2 billion people. About 300 million are carriers, with a prevalence of 20% in African, Asian, and Pacific region populations. Plasmatic and bioengineered recombinant vaccine type have been used in 30 million people. The first dose is given postnatally, the second at 1-2 months of age, and the 3rd at 1 year of age. Yellow fever vaccine was 50 years old in 1988, yet during 1986-1988 there were 5395 cases with 3172 deaths in Africa and South America. Vaccination provides 90-95% seroconversion, and periodic follow-up vaccinations under UIP could eradicate these infections and their etiologic agents.

We had 11 patients with
rubella
infection accompanied by hepatic dysfunction from 1979 through 1989. The elevations of sGOT were moderate, but sLDH levels were high. Extra hepatic manifestations were suspected by analysis of LDH isozymes. In 9 out of 11 patients, the sGPT levels returned to normal within 8 weeks. But prolonged courses of abnormal transaminase levels were observed in 2 patients. One was accompanied by underlying chronic hepatitis type non-A, non-B, and the other was supposed to have a prolonged
rubella
infection. Liver biopsy specimen taken from one patient in the acute phase demonstrated a non-specific reactive
hepatitis
. These observations suggest that
rubella
infection should be taken into consideration in making the diagnosis of sporadic
hepatitis
type non-A, non-B.

This survey of occupationally acquired infections in clinical laboratory workers was made by questionnaires to 306 hospitals in which 698 doctors and 8654 technicians worked. There were 177 probable infections during the previous decade (1979-88). In both doctors and technicians annual incidence rate of infection was 0.2% on an average. These included 77 cases of tuberculosis, 59 cases of HBV
hepatitis
, 24 cases of non-A, non-B
hepatitis
, 6 cases of
rubella
, 5 cases of HAV
hepatitis
, 2 cases of mycoplasmal pneumonia, one case of campylobacter enteritis, one case of paratyphus, one case of salmonellosis and one case of chicken pox. There were no fatal cases. In the recent two years the occurrence of HBV
hepatitis
among the clinical laboratory workers apparently has decreased, but tuberculosis and non-A, non-B
hepatitis
occurred unchangedly. Tuberculosis occurred frequently among the staff of the pathology laboratory (40 cases) and in bacteriology (25 cases), but rarely in biochemistry (3 cases) and in hematology (one case). On the other hand, HBV
hepatitis
occurred frequently among the staff of the biochemistry laboratory (33 cases) and in hematology (11 cases), but rarely in bacteriology (one case). These differences showed the existence of occupational exposure, but only 20% of these cases were due to recognized accidents. According to these results infection control practices for diminishing laboratory-associated infection must be performed.

Immunity status to measles, mumps,
rubella
and type B
hepatitis
(HB) viruses was studied in a cohort of 83 teen-agers (13-14 years). The vaccination against these agents is optional in Italy. Out of 83 subjects none had been vaccinated against measles, mumps and HB viruses, while 31 had had
rubella
vaccination. The percentage of seronegative adolescents was 2% for measles, 25% for mumps and 10% for
rubella
among unvaccinated teen-agers. These data suggest that even adolescent could be a target for
rubella
and mumps vaccination. On the contrary HBV does not appear to circulate extensively in the early years of life, so there is no need to extend the vaccination outside the risk groups. The presence of antibodies to measles, mumps and
rubella
viruses correlated very well with the anamnestic recall referred by the mothers. On the contrary for
rubella
and mumps viruses there was a high proportion of seropositive subjects with a negative history of disease. Therefore in the population under study asymptomatic infections with
rubella
and mumps viruses should have been rather frequent.

Diabetic patients have an increased proportion of their immunoglobulins nonenzymically glycated. To investigate the possibility that this may contribute to increased susceptibility to infection, we compared the immunoreactivity of glycated and nonglycated human immunoglobulins against
rubella
and
hepatitis
; streptococcal exoenzyme and infectious mononucleosis; human lymphocytotoxic antigens (HLA); and Varicella zoster in terms of antigen-antibody binding, cell agglutination, cytotoxicity, and complement-fixation properties, respectively. We found no evidence to support the supposition that glycated immunoglobulins are functionally impaired.

In the last years it has been suggested that idiopathic obstructive cholangiopathy is a pathologic process with evolutive studies: extrahepatic biliary atresia and neonatal
hepatitis
. The possibility of a viral agent as the inciting factor has been investigated. This report shows four male and one female with confirmed idiopathic obstructive cholangiopathy with different clinical picture. There was evidence of cytomegalovirus infection in two patients,
rubella
infection in one patient, hepatitis B virus infection in one patient and Epstein-Barr virus infection in one patient. While other causes of neonatal cholestasis were excluded, we suggest that those viruses has an etiologic role in the initial injury and the progression of the disease.

Guillain-Barre syndrome is known as one of the autoimmune disease, but the etiology, pathophysiology relating immune reaction, as well as the treatment are not established. It still causes physical handicap although its rate is low. The causes, clinical symptoms and outcome of 132 cases of Guillain-Barre syndrome have been analyzed. The patients' ages ranged from 4 months to 15 years. The antecedent events for 56.1% of the patients were known. These were upper respiratory tract infection, unexplained fever, vomiting, diarrhea, vaccination, measles,
german measles
, shigellosis, mumps,
hepatitis
, pertussis and surgery in order of frequency. The CSF protein level reached a maximum at 12.3 +/- 9.5 days. Steroids did not influence the outcome of this disease. More studies are necessary to conquer the disease.

The incidence of intrauterine infections during pregnancy is estimated to be about 14% when laboratory methods of detection are used. The commonest infections are cytomegalovirus infection, congenital rubella followed by herpes simplex. Hepatitis B virus infection occurs fairly frequently in this region of the world. Congenital syphilis, now highly treatable, is largely under control. Preventive measures are necessary since the lesions caused by some intrauterine infections are permanent and damaging. Immunisation against
hepatitis
and
rubella
is effective. Most of these infections are spread by close intimate contact. Hence, avoidance of such contact with persons with suspected infections would be wise during pregnancy.

Virus shedding was detected in 77% of homosexual subjects and in only 6% of heterosexual controls. The overall virus isolation rate in homosexual subjects was not significantly different among HIV-seropositive (79%) and HIV-seronegative (74%) individuals. In about 20% of homosexual subjects, virus shedding from multiple sites was observed. The most frequently isolated virus was cytomegalovirus (CMV) (41%), followed by enteroviruses (23%), herpes simplex virus (HSV) (7%), and adenoviruses (6%). In the control group, about 50% of subjects were seronegative for HSV-1 and 2, and about 70% were negative for CMV and Epstein-Barr virus (EBV). Only 2% of homosexuals were seronegative for CMV, about 5% for HSV-1 and 2, and about 20% for EBV. No differences were found in antibody levels against varicella-zoster virus (VZV) among the control and homosexual groups. The proportion of seronegatives for Coxsackie and
hepatitis
viruses was significantly higher in control than in homosexual subjects. However, no differences in the proportion of seronegatives for measles, mumps, and
rubella
were observed. No HIV-antibody-negative individual was detected with an OKT4/OKT8 ratio of less than 0.75. On the other hand, only HIV-positive subjects, with a ratio of less than 0.75, had high serum IFN alpha titers. The results suggest that the high rate of virus shedding among HIV-negative homosexual subjects might be a factor in the development of AIDS in this high-risk population.

Circulating immune complexes are thought to play an essential part in the pathogenesis of necrosing angiitis. This theory also allows a role to be attributed to certain infectious agents (viral, bacterial, parasitic) in the development of periarteritis nodosa (PAN). An infectious syndrome was found in all our 9 patients, aged 26 to 69 years, with histologically confirmed PAN: previous infection (over 15 days before hospital admission): otitis, hepatitis B, tonsillitis, ascaris (Case n.7), pulmonary tuberculosis, brucellosis, seropositivity for Chlamydia trachomatis (Case n.9), paratyphoid (Case n.5), seropositivity for Yersiniosis pseudo-tuberculosis (Case n.2), seropositivity for Chlamydia trachomatis (Cases 3 and 4), seropositivity for toxoplasmosis (Cases 4 and 6), seropositivity for
rubella
(Case n.8). Recent infection (less than 15 days before hospital admission): staphylococcus aureus septicaemia (Case n.1); Group A betahemolytic streptococcal urinary infection (Case n.2); Group A betahemolytic streptococcal otitis media; pseudomonas aeruginosa and Klebsiella septicaemia; enterococcal cystitis (Case n.4); progressive pulmonary tuberculosis (Case n.6), acinetobacter pneumonia (Case n.9). The HBs antigen was only found in one patient (Case n.6), who had an active
hepatitis
.
