Tabulation of monthly reports of infectious diseases from 19 countries and territories in the South and Central Pacific for the years 1973 through 1975 indicated that influenza-like illness, dengue, dysentery, measles, and gonorrhoea were the greatest problems. Reports of the leading causes of hospitalisation from 11 areas indicated that infectious respiratory disease, gastroenteritis and accidents were the most common problems requiring hospitalisation in most Pacific countries. The leading causes of death showed a different pattern with striking differences between traditional and modernised areas. It appeared that the major causes of death were changing from infectious diseases in the traditional areas to chronic diseases such as cardiovascular disease and cancer in the modernised areas.

The human herpes virus 6 (HHV6) is the causal agent of exanthem subitum (rose rash of infants). In addition, however, a wide range of other clinical manifestations are possible, the more common of these include: Untypical exanthem or uncharacteristic rash (with and without fever), acute respiratory disease (ARD) acute gastroenteritis and febrile convulsions (with and without exanthem). More uncommon, and in part unknown, clinical manifestations associated with HHV6 infection are discussed in Part 2 of this paper. In common with other herpes viruses, HHV6 also tends to show persistence and intermittent or chronic shedding in the normal population, making the unusually early infection of children (seroconversion in the first year of life in up to 80% of all children) understandable. This means that HHV6 infections manifesting in close temporal association with recommended vaccinations may be misinterpreted as complications of the vaccination. Today, the situation can be clarified by employing special virological-serological laboratory tests, which are available throughout the country.

Infants and young children with rotavirus (RV) or visualized adenovirus in their stools were tested for the simultaneous presence of a respiratory viral pathogen in their upper respiratory tract. Overall, at least 10.7% of 484 study subjects had such dual infections, including 8.3% of 385 RV-positive gastroenteritis patients and 24.3% of 37 RV-positive respiratory disease patients. Respiratory syncytial virus was present in 34.1% of 41 dual infections with RV and at least 40% of the 12 to 15 dual infections with visualized fecal adenovirus. Other pathogens found in the respiratory tract of patients with RV or visualized fecal adenovirus infections included influenza viruses, adenoviruses, parainfluenza viruses, rhinoviruses, and a cytomegalovirus.

The association between type of feeding and hospitalization during the first 18 months of life was examined among 1,058 infants from Jing-An district, Shanghai, People's Republic of China. Infants who had never been fed with mother's milk were categorized as artificially fed; the remainder were breast-fed. The rate of hospitalization for first episodes of respiratory infections during the first 18 months of life for the artificially fed infants was 18.0% v 11.2% for the breast-fed infants (P less than .01). Multiple logistic regression analysis demonstrated that the adverse effect of artificial feeding on the hospitalization rate for respiratory infections was independent of birth weight, father's education, passive smoking, and any case(s) of chronic respiratory disease in the family. The adjusted odds ratio for the artificially fed infants compared with the breast-fed infants was 2.11. The artificially fed infants were also hospitalized more frequently for gastroenteritis and other conditions, but the differences were not significant.

In 1963 the World Health Organization established a system for collecting and distributing information on viruses. By 1970, 93 laboratories in 33 countries were participating. The present study is an analysis of the reports on coxsackieviruses A and B and echoviruses for the 4 years 1967-70. Among the coxsackieviruses A, type 9 was reported most frequently, and the most frequently reported coxsackievirus B was type 3. Among the echoviruses, types 9, 6, and 30 were common. In the northern hemisphere the season of highest incidence for each of the three groups was June-October; in the southern hemisphere it was November-February. Most of the infections were in children and the clinical manifestations usually included aseptic meningitis, respiratory disease, skin eruptions, undifferentiated febrile illnesses, and gastroenteritis. The relative frequency of an association of a virus with a clinical syndrome differed not only between the three groups of viruses under study, but in a number of instances between the types within a group. As is well known there were a number of instances in which a specific clinical syndrome was linked to certain specific viruses-e.g., hand, foot, and mouth disease to certain types of coxsackievirus A, and myalgia (Bornholm disease) and cardiac conditions to coxsackieviruses B. There was also an apparent relation between age and symptoms-e.g., those due to the coxsackievirus B associated with Bornholm disease in persons over 15 years of age.

An average of 3481 preschool-age rural Indonesian children were re-examined every 3 months for 18 months. The mortality rate among children with mild xerophthalmia (night blindness and/or Bitot's spots) was on average 4 times the rate, and in some age groups 8 to 12 times the rate, among children without xerophthalmia. Mortality increased, almost linearly, with the severity of mild xerophthalmia (night blindness, Bitot's spots, and the two combined). These relations persisted after stratification for respiratory disease, wasting, gastroenteritis, pedal oedema, and childhood exanthems. Mild vitamin A deficiency was directly associated with at least 16% of all deaths in children aged from 1 to 6 years. These results suggest that mild xerophthalmia justifies vigorous community-wide intervention, as much to reduce childhood mortality as to prevent blindness, and that night blindness and Bitot's spots are as important as anthropometric indices in screening children to determine which of them need medical and nutritional attention.

Enteric types of adenovirus have recently been identified as a causative agent of infantile gastroenteritis. We utilized enzyme immunoassay and tissue culture techniques to evaluate prospectively the role of ET Ad in diarrhea occurring in hospitalized infants. We found that ET Ad was associated with 14 of 27 cases of diarrhea occurring during a 12-week study period in the late autumn and early winter months; ET Ad was found in the stool of only one of 72 children without diarrhea (P less than 0.001). Although adenoviruses other than ET Ad were found in the stools of two of the 27 children with diarrhea, such viruses were also found in the stools of five of 72 children without diarrhea and thus could not be statistically correlated with acute gastroenteritis. Children infected with ET Ad had diarrhea for a mean of 8.0 days, compared to a mean duration of 4.2 days for the children with gastroenteritis not associated with ET Ad. Thirteen of the 14 children with ET Ad gastroenteritis had respiratory symptoms such as cough, rhinorrhea, or wheezing, six had roentgenographic evidence of pneumonia, and three children had bilateral conjunctivitis. This study documents that ET Ad can be an important cause of acute gastrointestinal disease in hospitalized infants and young children and that gastrointestinal infections with ET Ad can be associated with a high rate of respiratory disease.

Enterovirus 71 (E-71) infection was first reported in 19745 in the United States; subsequent outbreaks were reported in worldwide distribution. In the summer of 1977, we identified 12 patients, mostly children, with E-71 infection. The striking feature of this outbreak is the occurrence of two cases with polio-like paralytic disease. Other diseases associated with E-71 included aseptic meningitis, meningoencephalitis, respiratory disease, gastroenteritis, and hand-foot-mouth disease. The spectrum of illness observed in our community was compared to that seen in other outbreaks. It is suggested that the significance of E-71 lies in its neuropathogenic potential.

The prevalence of infections with H1N1- and H3N2-influenza viruses, porcine respiratory coronavirus (PRCV), transmissible gastroenteritis virus (TGEV) and porcine epidemic diarrhoea virus (PEDV) in feeder pigs shortly after their entry into fattening units was examined. Ten groups of pigs with acute respiratory disease during the months September to October 1991 and seven groups of pigs with acute diarrhoea during the months February to March 1992 were investigated. On arrival in the fattening herds, more of the pigs were negative for antibodies against H1N1-influenza virus and against PRCV during September to October (61 and 50 per cent, respectively) than in February to March (51 and 34 per cent, respectively). There was serological evidence of a triple infection with PRCV and both influenza viruses in seven of the 17 groups; dual infections with PRCV and H1N1-influenza virus occurred in nine groups and with H1N1- and H3N2-influenza viruses in one group. Seroconversion against TGEV was not detected in any of the 17 groups, but seven of them had seroconverted to PEDV. Multiple infections with PRCV and either one or both of the influenza viruses were thus very common shortly after the introduction of feeder pigs into the fattening herds. There was no association between the type and/or multiplicity of these infections and respiratory disease, but infections with PEDV were clearly associated with outbreaks of diarrhoea.

Coronaviruses (CV) infect a variety of livestock, poultry and companion animals. They belong to at least five antigenic groups. CV cause localized infections of the respiratory and/or intestinal tracts, with the exception of feline infectious peritonitis virus (FIPV) and hemagglutinating encephalomyelitis (HEV) which cause systemic infections. The enteropathogenic CV infect the villous enterocytes resulting in villous atrophy leading to malabsorptive diarrhea. Several CV (bovine CV-BCV, porcine respiratory CV-PRCV, infectious bronchitis virus-IBV) cause respiratory disease. Current evidence indicates that protection against enteric and respiratory CV infections is mediated by passive or active immunity at the primary site of CV replication. Maternal vaccination approaches to induce passive immunity include the use of inactivated and modified live viral vaccines. Modified live viruses and a Ts mutant CV (FIPV) are also used as oral or intranasal vaccines to induce active mucosal immunity. The success of these vaccines in the field is often compromised by a number of potential problems. Coronaviruses are spherical, enveloped viruses, ranging from 80-160 nm in diameter and containing a positive-stranded RNA genome. They possess prominent surface spikes and some species display a fringe of smaller surface projections believed to be the hemagglutinin (HE). Coronaviruses possess 3 to 4 structural proteins: the spike (S) glycoprotein (150-200 kDa), the integral membrane glycoprotein (M; 20-30 kDa) and the nucleocapsid phosphoprotein (N; 43-50 kDa). A subset of CV (BCV, HEV, turkey CV) possess a third glycoprotein on the virion surface, the HE (60-65 kDa). These proteins can be quantitated using pooled monoclonal antibodies (mAb) to distinct epitopes of each protein in ELISA. Most research has focused on the S protein as a candidate antigen for CV vaccines since it induces virus neutralizing (VN) antibodies. However the HE protein stimulates the production of VN and HE inhibiting antibodies and the M protein induces antibodies that neutralize virus in the presence of complement. Attempts to correlate in vitro VN antibody activity with in vivo protection have shown that the passive transfer of VN mAb to the S or HE protein conferred passive protection against CV challenge in some studies, but not others. Additional research has implicated a possible role for other CV proteins in immunity. Studies of mAb to the M protein of transmissible gastroenteritis (TGEV) have provided evidence for a direct role of the M protein in the induction of alpha IFN by porcine blood leukocytes. The potential significance of this phenomenon to immunity to TGEV is unclear.(ABSTRACT TRUNCATED AT 400 WORDS)
