Background: Measles is a feverish condition labeled among the most infectious viral illnesses in the globe. Despite the presence of a secure, accessible, affordable and efficient vaccine, measles continues to be a worldwide concern. Methods: This study uses machine learning and time series methods to assess factors that placed people at a higher risk of measles. This historical cohort study contained the Measles incidence in Markazi Province, the center of Iran, from April 1997 to February 2020. Logistic regression, linear discriminant analysis, random forest, artificial neural network, bagging, support vector machine, and naïve Bayes were used to make the classification. Zero-inflated negative binomial regression for time series was utilized to assess development of measles over time. Results: The prevalence of measles was 14.5% over the recent 24 years and a constant trend of almost zero cases was observed from 2002 to 2020. The order of independent variable importance were recent years, age, vaccination, rhinorrhea, male sex, contact with measles patients, cough, conjunctivitis, ethnic, and fever. Younger age, less probability of contact and no fever is associated with less odds of zero cases. Only 7 new cases were forecasted for the next two years. Bagging and random forest were the most accurate classification methods. Conclusion: Even if the numbers of new cases are almost zero during the recent years, it has been showed that age and contact are responsible for non-occurrence of measles. October and May are prone to have new cases for 2021 and 2022.

Background Human papilloma virus (HPV) is the most common sexually transmitted infection worldwide. This study aimed at evaluation of women’s knowledge about HPV and HPV vaccine and identification of related factors conducted on 400 reproductive-aged women referred to health care centers in Arak, Iran. Methods A researcher-made questionnaire was applied to assess the participants’ knowledge regarding HPV and HPV vaccine among Iranian reproductive-aged women. Results Most participants were married (82%), diploma (34.6%), had two children (32.2%), and lived in an urban area (93%).The mean age among the studied population was 32.5 years. The associated HPV and vaccine knowledge were evaluated as insufficient in 86.5% and 79% of the participants, respectively. Out of 400, 37.5% and 34.5% of participants knew that the HPV vaccine protected against cervical cancer and genital warts, respectively. Our results revealed that the knowledge of the infection and its ways of protection were significantly higher in well-educated women. What is more, the awareness declined in those with more children in the family. Conclusions The level of understanding in terms of the incidence and also prevention was evaluated poor in our study. This highlights that further campaigns are required to improve it. Vaccination programs should be seriously considered to prevent HPV infection and its complications like cervical cancer.
