Abstract We investigated an outbreak of encephalitis in Tangail District, Bangladesh. defined case-patients as persons from the area whom fever developed with new onset seizures or altered mental status December 15, 2004, through January 31, 2005. Twelve met definition; 11 (92%) died. Serum specimens were available 3; 2 had immunoglobulin M antibodies against Nipah virus by capture enzyme immunoassay. enrolled and 33 neighborhood controls a case-control study. The only exposure significantly...
Abstract Human Nipah outbreaks recur in a specific region and time of year Bangladesh. Fruit bats are the reservoir host for virus. We identified 23 introductions virus into human populations central northwestern Bangladesh from 2001 through 2007. Ten affected multiple persons (median 10). Illness onset occurred December May but not every year. 122 cases infection. The mean age case-patients was 27 years; 87 (71%) died. In 62 (51%) virus–infected patients, illness developed 5–15 days after...
Nipah virus (NiV) is an emerging bat-borne zoonotic that causes near-annual outbreaks of fatal encephalitis in South Asia-one the most populous regions on Earth. In Bangladesh, infection occurs when people drink date-palm sap contaminated with bat excreta. Outbreaks are sporadic, and influence viral dynamics bats their temporal spatial distribution poorly understood. We analyzed data host ecology, molecular epidemiology, serological dynamics, genetics to characterize spatiotemporal patterns...
Nipah virus is a highly virulent zoonotic pathogen that can be transmitted between humans. Understanding the dynamics of person-to-person transmission key to designing effective interventions.
We investigated a cluster of patients with encephalitis in the Manikgonj and Rajbari Districts Bangladesh February 2008 to determine etiology risk factors for disease.We classified persons as confirmed Nipah cases by presence immunoglobulin M antibodies against virus (NiV), or NiV RNA isolation from cerebrospinal fluid throat swabs who had onset symptoms between 6 March 10, 2008. probable if they reported fever convulsions altered mental status, resided outbreak areas during that period,...
Objective To characterize influenza seasonality and identify the best time of year for vaccination against in tropical subtropical countries southern south-eastern Asia that lie north equator.Methods Weekly surveillance data 2006 to 2011 were obtained from Bangladesh, Cambodia, India, Indonesia, Lao People's Democratic Republic, Malaysia, Philippines, Singapore, Thailand Viet Nam.Weekly rates activity based on percentage all nasopharyngeal samples collected during tested positive virus or...
Nipah virus (NiV) is a paramyxovirus, and Pteropus spp. bats are the natural reservoir. From December 2010 through March 2014, hospital-based encephalitis surveillance in Bangladesh identified 18 clusters of NiV infection. The source infection for case-patients 3 2 districts was unknown. A team epidemiologists anthropologists investigated these comprising 14 case-patients, 8 whom died. Among drank fermented date palm sap (tari) regularly before their illness, 6 provided care to person...
Active Nipah virus encephalitis surveillance identified an cluster and sporadic cases in Faridpur, Bangladesh, January 2010. We 16 case-patients; 14 of these patients died. For 1 case-patient, the only known exposure was hugging a deceased patient with probable case, while another case-patient's involved preparing same corpse for burial by removing oral secretions anogenital excreta cloth bare hands. Among 7 persons confirmed cases, 6 died, including physician who had physically examined...
Whether an individual becomes infected in infectious disease outbreak depends on many interconnected risk factors, which may relate to characteristics of the (e.g., age, sex), his or her close relatives household members), wider community. Studies monitoring individuals households schools have helped elucidate determinants transmission small social structures due advances statistical modeling; but such approach has so far largely failed consider context they live in. Here, we used...
Background. Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections in young children globally, with highest burden low- and middle-income countries where association between RSV activity climate remains unclear. Methods. Monthly laboratory-confirmed cases associations data were assessed for surveillance sites tropical subtropical areas (Bangladesh, China, Egypt, Guatemala, Kenya, South Africa, Thailand) during 2004–2012. Average monthly minimum maximum...
Preventing emergence of new zoonotic viruses depends on understanding determinants for human risk. Nipah virus (NiV) is a lethal pathogen that has spilled over from bats into populations, with limited person-to-person transmission. We examined ecologic and behavioral drivers geographic variation risk NiV infection in Bangladesh. visited 60 villages during 2011-2013 where cases were identified 147 control villages. compared case most likely infection, including number bats, persons, date palm...
Breast cancer is a global health issue and leading cause of death among women. Early detection through increased awareness knowledge on breast screening thus crucial. The aim the present study was to assess effect an educational intervention program practice self-examination young female students university in Bangladesh.A quasi-experimental (pre-post) design conducted at Jahangirnagar University Bangladesh. Educational information (BSE), demonstration BSE procedure leaflets were distributed...
Background Recent population-based estimates in a Dhaka low-income community suggest that influenza was prevalent among children. To explore the epidemiology and seasonality of throughout country all age groups, we established nationally representative hospital-based surveillance necessary to guide prevention control efforts. Methodolgy/Principal Findings We conducted influenza-like illness severe acute respiratory sentinel 12 hospitals across Bangladesh during May 2007–December 2008....
During August 2009–October 2010, a multidisciplinary team investigated 14 outbreaks of animal and human anthrax in Bangladesh to identify the etiology, pathway transmission, social, behavioral, cultural factors that led these outbreaks. The identified 140 cases 273 cutaneous anthrax. Ninety one percent persons whom developed had history butchering sick animals, handling raw meat, contact with skin, or were present at slaughtering sites. Each year, Bacillus anthracis identical genotypes...
To determine how much influenza contributes to severe acute respiratory illness (SARI), a leading cause of death in children, among people all ages Bangladesh.Physicians obtained nasal and throat swabs test for virus from patients who were hospitalized within 7 days the onset infection (SARI) or consulted as outpatients influenza-like (ILI). A community health care utilization survey was conducted proportion hospital catchment area residents sought at study hospitals calculate incidence...
Background Pneumonia is the leading cause of childhood death in Bangladesh. We conducted a longitudinal study to estimate incidence virus-associated pneumonia children aged <2 years low-income urban community Dhaka, Methods followed cohort for two years. collected nasal washes when presented with respiratory symptoms. Study physicians diagnosed cough and age-specific tachypnea positive lung findings as case-patients. tested samples syncytial virus (RSV), rhinoviruses, human metapneumovirus...
Abstract It is currently unclear whether changes in viral communities will ever be predictable. Here we investigate wildlife are inherently structured (inferring predictability) by looking at assembled through deterministic (often predictable) or stochastic (not processes. We sample macaque faeces across nine sites Bangladesh and use consensus PCR sequencing to discover 184 viruses from 14 families. then network modelling statistical null-hypothesis testing show the presence of non-random...
A large outbreak of hepatitis E occurred in urban Bangladesh during 2008–2009, resulting increased maternal and neonatal mortality the affected community. Case-patients who took paracetamol their illness were more likely to die than other case-patients. Background. Hepatitis virus (HEV) causes outbreaks jaundice associated with mortality. Four deaths among pregnant women an community near Dhaka, Bangladesh, late 2008 reported authorities January 2009. We investigated etiology risk factors...
SUMMARY Drinking raw date palm sap is the primary route of Nipah virus (NiV) transmission from bats to people in Bangladesh; subsequent person-to-person common. During December 2010 March 2011, we investigated NiV epidemiology by interviewing cases using structured questionnaires, in-depth interviews, and group discussions collect clinical exposure histories. We conducted a case-control study identify risk factors for transmission. identified 43 cases; 23 were laboratory-confirmed 20...
Several coronavirus disease (COVID-19) vaccines have already been authorized and distributed in different countries all over the world, including Bangladesh. Understanding public acceptance of such a novel vaccine is vital, but little known about topic.
