Human papillomavirus (HPV) vaccination program in Sri Lanka: Ongoing costs and operational context of a routinized program.

Existing evidence on the cost of human papillomavirus (HPV) vaccination programs has focused on pilot and demonstration projects or initial introductions, which resulted in a perceived high cost. We aimed to study the ongoing cost and operational context of an established HPV vaccination program in Sri Lanka. We conducted a retrospective operational research and microcosting study focusing on 2019.

Cost and operational context for national human papillomavirus (HPV) vaccine delivery in six low- and middle-income countries.

Introduction: There are concerns from immunization program planners about high delivery costs for human papillomavirus (HPV) vaccine. Most prior research evaluated costs of HPV vaccine delivery during demonstration projects or at introduction, showing relatively high costs, which may not reflect the costs beyond the pilot or introduction years. This study sought to understand the operational context and estimate delivery costs for HPV vaccine in six national programs, beyond their introduction years.

Predictive modelling for COVID-19 outbreak control: lessons from the navy cluster in Sri Lanka.

In response to an outbreak of coronavirus disease 2019 (COVID-19) within a cluster of Navy personnel in Sri Lanka commencing from 22nd April 2020, an aggressive outbreak management program was launched by the Epidemiology Unit of the Ministry of Health. To predict the possible number of cases within the susceptible population under four social distancing scenarios, the COVID-19 Hospital Impact Model for Epidemics (CHIME) was used. With increasing social distancing, the epidemiological curve flattened, and its peak shifted to the right.

Spatiotemporal distribution of cutaneous leishmaniasis in Sri Lanka and future case burden estimates.

Background: Leishmaniasis is a neglected tropical vector-borne disease, which is on the rise in Sri Lanka. Spatiotemporal and risk factor analyses are useful for understanding transmission dynamics, spatial clustering and predicting future disease distribution and trends to facilitate effective infection control.

Methods: The nationwide clinically confirmed cutaneous leishmaniasis and climatic data were collected from 2001 to 2019.

Spatial Epidemiologic Trends and Hotspots of Leishmaniasis, Sri Lanka, 2001-2018.

Leishmaniasis, a neglected tropical disease, is on the decline in South Asia. However, cases of cutaneous leishmaniasis have risen in Sri Lanka since 2001, and the lack of in-depth research on its epidemiologic characteristics hampers control efforts. We analyzed data collected from patients with cutaneous leishmaniasis in Sri Lanka during 2001-2018 to study temporal and geographic trends and identify and monitor disease hotspots.

Prevalence and risk factors for impaired kidney function in the district of Anuradhapura, Sri Lanka: a cross-sectional population-representative survey in those at risk of chronic kidney disease of unknown aetiology.

Background: Over the last 20 years there have been reports of a form of chronic kidney disease of unknown cause (CKDu) affecting rural communities in the North Central Province of Sri Lanka. Valid prevalence estimates, using a standardised methodology, are needed to assess the burden of disease, assess secular trends, and perform international comparisons.

Methods: We conducted a cross-sectional representative population survey in five study areas with different expected prevalences of CKDu.

Poliovirus Type 2 Seroprevalence Following Full- or Fractional-Dose Inactivated Poliovirus Vaccine in the Period After Sabin Type 2 Withdrawal in Sri Lanka.

Background: In July 2016, Sri Lanka replaced 1 intramuscular dose of inactivated poliovirus vaccine (IPV) with 2 doses of intradermal fractional-dose IPV (fIPV) in its routine immunization schedule. We carried out a survey of seroprevalence of antipolio antibodies in children who received 2 fIPV doses and compared it with those who received 1 full IPV dose.

Methods: Children born between March and December 2016 were randomly selected from 3 Sri Lankan districts (Colombo, Badulla, and Anuradhapura).

National introduction of fractional-dose inactivated polio vaccine in Sri Lanka following the global "switch".

As part of the Polio eradication and endgame strategic plan 2013-2018 to achieve and sustain a polio-free world, the use of oral polio vaccine (OPV) must eventually be stopped. This process started in April 2016, with the worldwide, planned synchronized "switch", whereby use of OPV containing poliovirus type 2 ceased. Prior to the switch, in line with international guidance on risk mitigation, Sri Lanka had introduced a single full dose (0.

Interventions for increasing chlamydia screening in primary care: a review.

Background: Despite guidelines recommending opportunistic chlamydia screening of younger women, screening rates in some countries remain low. Our aim was to review the evidence for specific interventions aimed at increasing chlamydia screening rates in primary care.

Methods: A Medline search was conducted for controlled trials that assessed the effectiveness of interventions aimed at improving chlamydia screening rates in primary health care settings.

Rising HIV notifications in Australia: accounting for the increase in people living with HIV and implications for the HIV transmission rate.

Background: To describe the changes in notification rates for HIV, as a proportion of people living with HIV infection, in Australia.

Methods: Notification data on HIV and AIDS-related deaths published by the National Centre in HIV Epidemiology and Clinical Research were obtained and analysed for the period of 1988-2004.

Results: The annual HIV notification rate per 100 people living with HIV fell significantly between 1988 and 1999 for all HIV cases and for men who have sex with men (MSM) specifically (P < 0.

Antibiotic consumption and chlamydia prevalence in international studies.

Background: To determine whether there is an ecological association between antibiotic use and chlamydia prevalence.

Methods: A systematic review was undertaken of international studies on chlamydia prevalence among women aged 15-25 years published between 2000 and 2005. Preference was given to studies using nucleic acid testing and representative population-based sampling methods.
