Abstract
Measles is an acute, highly contagious disease with a high mortality rate in children. Although vaccination has reduced measles incidence, outbreaks still occur. Therefore, in this study, we aimed to investigate the frequency of antimeasles immunoglobulin G (IgG) antibody (Ab) among students at Shiraz University of Medical Sciences (SUMS). Four hundred fifty SUMS students were enrolled in this cross-sectional study. Information on demographics and measles vaccination history was collected using a questionnaire. Participants were divided into two groups, including A and B, according to routine doses of measles vaccine and the national measles/rubella immunization program. The antimeasles IgG Abs were tested using a commercial Enzyme-Linked Immunosorbent Assay Kit. Participants ranged in age from 18 to 48 years, with a mean age of 22.2 (±4.3). Fifty percent of the subjects were male. Our results showed that 63.6% of the cases were positive for antimeasles IgG Abs. The seroprevalence of IgG Abs between groups A and B did not differ significantly (p = 0.612). There was also no significant correlation between the seroprevalence of antimeasles IgG Abs and the age (p = 0.43) or sex (p = 0.24) of the subjects. The results showed that the frequency of antimeasles IgG Abs is lower than required to prevent the measles virus from circulating. Therefore, a booster vaccination may be necessary.

Abstract
PURPOSE Adenoviral-mediated keratoconjunctivitis is among the emergency diseases of ophthalmology with long-term sequels. The role of adenovirus infection, ocular-related genotypes, and association with ocular symptoms need to be investigated for epidemiological as well as clinical purposes. METHODS The affected patients from two close keratoconjunctivitis epidemics were included in the study. The swab samples were taken from patients; the total DNA was extracted and then used as a template for in-house Real-time PCR. Besides, partial Hexon genes of 11 adenovirus positive samples were amplified and submitted to sanger sequencing. Moreover, they were finally evaluated by phylogenetic analysis. RESULTS Of 153 patients, 92 (60.1%) were males and 47 cases (30.7%) had a history of eye infection in the family or colleagues. Real-time PCR tests of 126 samples (82.4%) were positive for adenovirus, and all eleven cases that underwent sequencing analysis were determined to be group 8 (HAdV-D8). Adenovirus infection has a significant relationship with infection among family or colleagues (p = 0.048), membrane formation (p = 0.047), conjunctival bleeding (p = 0.046), tearing, and pain(p < 0.05). CONCLUSIONS The results indicated that Adenovirus is the major cause of keratoconjunctivitis, and HAdV-D8 was the most common genotype in the area. There were some clinical manifestations associated with Adenovirus infection of the conjunctiva.
