Dynamic Forecasting of Zika Epidemics Using Google Trends.

We developed a dynamic forecasting model for Zika virus (ZIKV), based on real-time online search data from Google Trends (GTs). It was designed to provide Zika virus disease (ZVD) surveillance and detection for Health Departments, and predictive numbers of infection cases, which would allow them sufficient time to implement interventions. In this study, we found a strong correlation between Zika-related GTs and the cumulative numbers of reported cases (confirmed, suspected and total cases; p<0.001). Then, we used the correlation data from Zika-related online search in GTs and ZIKV epidemics be…

[Resurgence of yellow fever epidemics in Côte-d'Ivoire].

Resurgence of yellow fever epidemics in Côted'Ivoire remains a major problem of public health. To describe this disease through the early alarm system of National Institute of Public Hygiene (NIPH) is convenient to us. This is a cross-sectional study with descriptive aiming, which proceeded with epidemiological surveillance service of NIPH. The data were collected over 7 years (from 2001 to 2007), starting from the cards of notification, reports, and registers of the service. The main findings of our study are that: 1) we listed 1468 suspect cases including 41 confirmed and the lethality rate …

Серьезные эпидемии денге в Шри-Ланке, 2003-2006 годы.

Недавняя вспышка геморрагической лихорадки денге на индийском субконтиненте хорошо задокументирована в Шри-Ланке. Мы сравниваем последние (2003-2006 годы) и прошлые (1980-1997 годы) данные наблюдения за денге по Шри-Ланке. Серотипы 4 денге (DENV) в Шри-Ланке соотносятся более 30 лет. За этот период новый генотип DENV-1 заменил старый генотип. Кроме того, новые клещи вирусов генотипа III DENV-3 заменили старые клинки. Возникновение новых клинков DENV-3 в 1989 и 2000 годах совпало с резким увеличением числа зарегистрированных случаев заболевания денге, связанных с этим серотипом в серьезных эпид

Recent emergence of dengue hemorrhagic fever in the Indian subcontinent has been well documented in Sri Lanka. We compare recent (2003-2006) … d with abrupt increases in the number of reported dengue cases, implicating this serotype in severe epidemics. In 1980-1997, most reported dengue cases were in children. Recent epidemics have been characterized by many cases in children and adults. Changes in local transmission dynamics and genetic changes in DENV-3 are likely increasing emergence of severe …

Epidemics to eradication: the modern history of poliomyelitis.

Poliomyelitis has afflicted humankind since antiquity, and for nearly a century now, we have known the causative agent, poliovirus. This pathogen is an enterovirus that in recent history has been the source of a great deal of human suffering. Although comparatively small, its genome is packed with sufficient information to make it a formidable pathogen. In the last 20 years the Global Polio Eradication Initiative has proven successful in greatly diminishing the number of cases worldwide but has encountered obstacles in its path which have made halting the transmission of wild polioviruses a pr

The transmissible spongiform encephalopathies: emerging and declining epidemics.

TSEs (transmissible spongiform encephalopathies) are neurodegenerative diseases of various mammalian species, the best known of which include BSE (bovine spongiform encephalopathies) in cattle, CJD (Creutzfeldt-Jakob disease) in humans, scrapie in sheep and CWD (chronic wasting disease) in deer. This review examines the emergence of various TSE strains and their transmission, and discusses disease surveillance and control.

Timely detection of meningococcal meningitis epidemics in Africa.

BACKGROUND: Epidemics of meningococcal disease in Africa are commonly detected too late to prevent many cases. We assessed weekly meningitis incidence as a tool to detect epidemics in time to implement mass vaccination. METHODS: Meningitis incidence for 41 subdistricts in Mali was determined from cases recorded in health centres (1989-98) and from surveillance data (1996-98). For incidence thresholds of 5 to 20 cases per 100000 inhabitants per week, we calculated sensitivity and specificity for detecting epidemics, and determined the time lapse between threshold and epidemic peak. FINDINGS: …
