Background: International travel during the Coronavirus disease 2019 (COVID-19) pandemic carries a certain magnitude of infection risk both to travelers and their destination, which may be difficult to assess in the early stage. The characteristics of common infectious diseases of tourists may provide some clues to identify the high-risk travelers and protect susceptible population.Methods: From among 48,444 travelers screened at Shanghai Port, we analyzed 577 travelers with 590 infectious diseases for age, sex, disease type, and World Health Organization (WHO) regions. We used the Joinpoint Regression Program to identify the average percent changes (APC) in the various trends among these individuals.Results: Hepatitis B, syphilis, and HIV were the most common infectious diseases in travelers entering China, and Hepatitis B, pulmonary tuberculosis, and syphilis in Chinese nationals traveling abroad (overall detection rates, 1.43 and 0.74%, respectively; P < 0.05). Africa (2.96%), the Americas (1.68%), and the Western Pacific (1.62%) exhibited the highest detection rates. This trend did not decrease since the COVID-19 pandemic (P > 0.05) and rather showed an upward trend with increasing age [APC 95% CI = 5.46 (3.41,7.56)%, P < 0.05]. However, there were no evident trends in monthly infection rates of travelers exiting and entering China from different WHO regions (all P > 0.05).Conclusion: Travelers always carry a transmission risk of common infectious diseases. It may be reasonable to adjust strategies for airport screening and quarantine according to the age and departure area of travelers to prevent and control new infectious diseases.

INTRODUCTION: The dengue hemorrhagic dengue (DHF) remains an important public health problem in Brazil. The objective of this study was to analyze the epidemiological characteristics of DHF cases during the 2003 epidemic in Ceará. METHODS: Suspected DHF cases with onset of symptoms between January and December 2003 were investigated. RESULTS: 37,964 classic dengue cases and 291 DHF cases were reported. Among the cases discarded, 75.5% were serologically positive but did not meet the criteria recommended by the World Health Organization (WHO). The DHF patients' median age was 30 years (2 - 88). Among the hemorrhagic manifestations, petechiae were the most (32.6%) frequent. Cases of gastrointestinal bleeding, ascites, pericardial pleural effusion, hepatomegaly, hypotension and shock showed higher risk of progression to death (p <0.05). CONCLUSIONS: The introduction of a new serotype (DENV-3) in Ceará, which encountered a susceptible population and high vector density, may have been the primary agent responsible for the magnitude of the epidemic. Timely and appropriate medical care, along with an organized care structure are essential for reducing its lethality.

Abstract Objective The novel coronavirus disease 2019 (COVID-19) infection was declared as a pandemic by the World Health Organization on March 11, 2020. Although the complaint of anosmia is well described in adult patients, there is limited knowledge in pediatric patients. We aim to evaluate the epidemiological characteristics and clinical findings of children with anosmia in COVID-19-positive pediatric patients. Methods Patients diagnosed with COVID-19 infection at 1 month to 18 years of age, who admitted to Meram Faculty of Medicine of Necmettin Erbakan University between March and June 2020, were retrospectively reviewed, and the patients who had anosmia or developed anosmia during follow-up were then included in the study. The diagnosis was established by polymerase chain reaction (PCR). Results A total of 71 patients were diagnosed with COVID-19 and 14 (19.7%) of them had anosmia. Mean patient age was 14.07 (range: 10–16) years. Six of our 14 (42.8%) patients had anosmia at the time of diagnosis and anosmia developed in the follow-up among eight patients. The mean duration of anosmia in our patients was 6.9 ± 3.8 days. Recovery time was 1 to 4 days in four patients (28.5%), 5 to 8 days in four patients (28.5%), and 9 to 14 days in six patients (42.8%). Conclusion In this article, it was emphasized that anosmia can be the sole manifestation or concomitant with other symptoms in children with COVID-19 disease. Care and attention is important to identify COVID-19 patients at an early stage of the disease and limit the spread of the virus.

Background: Expatriates represent >80% of Qatar’s population, mostly arriving from countries in Africa and Asia that are endemic with many diseases. This increases the risk for introducing new pathogens into the country and provides a platform for maintenance of endemic pathogen circulation. Here, we report on the incidence and epidemiological characteristics of hepatitis B in Qatar between 2010 and 2014. Methods: We performed a retrospective epidemiological data analysis using the data available at the surveillance system of the Ministry of Public Health (MOPH) in Qatar. Data were collected from distinctive public and private incorporates around the nation. Reported cases of hepatitis B patients represent those who met the stringent case definition as per World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) guidelines and eventually reported to MOPH. Results: The annual incidence rates of hepatitis B cases were 30.0, 34.2, 30.5, 39.4, and 19.8 per 100,000 population in 2010, 2011, 2012, 2013, and 2014, respectively. There was no specific trend or seasonality for the reported cases. The incidence rates were higher in females compared to males between 2010 and 2012, but similar in 2013 and 2014. The highest incidence rates were reported among individuals between 25 and 34 years of age. No cases were reported in children younger than five years in 2013 and 2014. Rates of hepatitis B cases declined dramatically in 2014, in both Qataris and non-Qataris, as compared to the previous years. Conclusion: Our results indicate a dramatic decline of hepatitis B cases in Qatar but mandate improved surveillance and vaccination efforts in expatriates in the nation.

Epidemiological Characteristics

Currently, the world is facing a health and socioeconomic crisis caused by the novel coronavirus disease COVID-19. On 11 March 2020, the World Health Organization (WHO) has declared this disease as a pandemic. The condition (COVID-19) is an infectious disorder triggered by a newly discovered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2. Most of the COVID-19 infected patients will experience mild to moderate respiratory symptoms and recover without any unique therapy. Assessment of the clinical and epidemiological characteristics of SARS-CoV-2 cases suggests the infected patients will not be contagious until the onset of severe symptoms and affects the other organs. Well-differentiated cells of apical airway epithelia communicating with ACE2 were promptly infected to SARS-CoV-2 virus. But the expression of ACE 2 in poorly differentiated epithelia facilitated SARS spike (S) protein-pseudo typed virus entry and it is replicated in polarized epithelia and especially exited via the apical surface. Limiting the transmission of COVID-19 infection & its prevention can be regarded as a hierarchy of controls. In this article, we briefly discuss the most recent advances in respect to aetiology, pathogenesis and clinical progression of the disease COVID-19.

Especially dangerous infections (EDIs) belong to the conditionally labelled group of infectious diseases that pose an exceptional epidemic threat. They are highly contagious, rapidly spreading and capable of affecting wide sections of the population in the shortest possible time, they are characterized by the severity of clinical symptoms and high mortality rates. At the present stage, the term "especially dangerous infections" is used only in the territory of the countries of the former USSR, all over the world this concept is defined as "infectious diseases that pose an extreme threat to public health on an international scale." Over the entire history of human development, more people have died as a result of epidemics and pandemics than in all wars combined. The list of especially dangerous infections and measures to prevent their spread were fixed in the International Health Regulations (IHR), adopted at the 22nd session of the WHO's World Health Assembly on July 26, 1969. In 1970, at the 23rd session of the WHO's Assembly, typhus and relapsing fever were excluded from the list of quarantine infections. As amended in 1981, the list included only three diseases represented by plague, cholera and anthrax. However, now annual additions of new infections endemic to different parts of the earth to this list take place. To date, the World Health Organization (WHO) has already included more than 100 diseases in the list of especially dangerous infections.

This essay clarifies the author’s objections to COVID-19 vaccine credentials voiced in “The Ethics of COVID-19 Vaccine Passports.” The author’s objections centered on discriminatory practices based on vaccine status for domestic social and work activities, but he agrees with the World Health Organization that these credentials should not be required for international travel. In addition, there is a significant ethical different between currently available COVID-19 vaccines and the yellow fever vaccine because the former are produced or tested using abortion-derived cell lines. The yellow fever vaccine is much less ethically problematic. This situation could change with the approval of new COVID-19 vaccines without links to abortion-derived cell lines.

The new coronavirus (COVID-19) is a disease that is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). On 11 March 2020, the coronavirus outbreak has been labelled a global pandemic by the World Health Organization. In this context, chest X-ray imaging has become a remarkably powerful tool for the identification of patients with COVID-19 infections at an early stage when clinical symptoms may be unspecific or sparse. In this work, we propose a complete analysis of separability of COVID-19 and pneumonia in chest X-ray images by means of Convolutional Neural Networks. Satisfactory results were obtained that demonstrated the suitability of the proposed system, improving the efficiency of the medical screening process in the healthcare systems.

In infectious diseases, viral hepatitis has an increased incidence, being an important cause of morbidity and mortality, being a "sentinel" indicator of the socio-economic and hygienic-cultural standard of a geographical area. The World Health Organization (WHO) admits the following types of hepatitis viruses: A, B, B + D, C, E, F and G. Among the viral entities recognized by the WHO, a special importance in terms of incidence, evolution over time with the risk of chronicity and the therapeutic options are presented by hepatitis B and C. There is currently an effective vaccine as well as treatment for hepatitis B. There is no vaccine for hepatitis C, but in recent years considerable progress has been made in treating this disease. Also, the introduction of drugs known as direct-acting antivirals makes it possible to cure over 90% of patients within 2-3 months. But in many countries, current drug policies, regulations and prices keep treatment out of the reach of most people with hepatitis. Eradication of viral hepatitis is possible if greater emphasis is placed on prevention, diagnosis and treatment. Vaccination is very important, as it is possible for types A and B of hepatitis. Early diagnosis is also extremely important, given that there are currently very effective drugs that can prevent the development of liver cancer. The WHO also noted that about two million people worldwide become ill each year due to the reuse of syringes and stressed the importance of checking blood donors to see if they are not carriers of hepatitis B or C viruses. Therefore, the purpose of this article is to highlight the pharmacological treatment and the main therapeutic and prevention schemes currently used for patients with these liver diseases. The paper was based on the most popular methods of identification of the latest international information about the treatment of hepatitis (by electronic search using Pubmed, SciFinder, Scirus, GoogleScholar and Web of Science). We also consulted the global literature cited in the hepatitis database of the World Health Organization (WHO) updated frequent from the current literature on this topic.
