Melioidosis, which is mainly prevalent in Thailand and Australia, has shown an increasing trend in India in the last few years. We carried out a retrospective study of 25 culture-proven adult cases of melioidosis who were admitted to a tertiary care hospital in southern India during June 2001 to September 2007. There was a six-fold increase in the number of cases in 2006 and 2007 as compared to 2001. ⋯ The clinical presentations were fever (80%), pneumonia and/or pleural effusion (48%), hepatomegaly (56%), joint involvement, and/or osteomyelitis (48%), splenomegaly (40%), splenic abscess (24%) and septicemia (28%). The organism, Burkholderia pseudomallei, was sensitive to co-amoxiclav, cotrimoxazole, ceftazidime, and carbapenem. The study suggests that melioidosis is an emerging infectious disease in the southwestern coastal belt of India, and it is likely to happen at much higher incidence.

Cost-effectiveness of rotavirus vaccination as part of the national immunization program for Thai children.
Rotavirus infection is a common cause of gastroenteritis in infants and thus, presents an economic burden. Currently, there are effective vaccines against rotavirus licensed for use in Thailand. We evaluated the cost-effectiveness of rotavirus vaccination as part of the national immunization program for Thai children based on information derived from studies of disease burden of rotavirus infection, vaccine effectiveness, expenditure for care according to the WHO CHOICE; average GNP per capita provided by the Bank of Thailand and statistics from the Ministry of Health. ⋯ At a maximum vaccine price of USD6.2-10.5 per dose, the cost-effectiveness ratio is approximately USD185-759 per DALY averted. Vaccine price is greatly influenced by vaccine efficacy, mortality and G genotypes of rotavirus. Rotavirus vaccination could reduce gastroenteritis in children but the price, if used as part of the national immunization program should be below USD10 per dose.

Outbreak of chikungunya fever in Thailand and virus detection in field population of vector mosquitoes, Aedes aegypti (L.) and Aedes albopictus Skuse (Diptera: Culicidae).
We investigated chikungunya fever outbreak in the southern part of Thailand. Human plasma specimens obtained from suspected patients and adult wild-caught mosquitoes were detected for chikungunya virus employing reverse transcriptase-polymerase chain reaction technique. ⋯ The appearance of chikungunya virus in adult male mosquitoes of both species reveals a role of transovarial transmission of the virus in field population of the mosquito vectors. These findings have provided further understanding of the relationship among mosquito vectors, chikungunya virus and epidemiology of chikungunya fever in Thailand.

Knowledge, attitudes, and acceptability of a human papillomavirus vaccine among healthcare providers.
A cross-sectional survey was conducted to evaluate acceptability, knowledge, and attitude regarding HPV, cervical cancer, and HPV vaccine among healthcare providers working in hospitals located in Bangkok, Thailand. Two hundred nurses and 100 doctors from three government hospitals and one private hospital were recruited. Data collection was done using a self-administered questionnaire. ⋯ Approximately 80% of nurses and 63% of doctors agreed on the use of a HPV vaccination. Almost all the nurses and doctors suggested that adolescent aged < or = 18-years-old should be the target group for HPV vaccination. Furthermore, 73% of nurses and 76% of doctors would recommend clients to receive HPV vaccine.

Anti-tuberculosis drug resistance and HIV co-infection in Phnom Penh, Cambodia.
The objective of this study was to observe the prevalence of drug resistance in Mycobacterium tuberculosis isolates in HIV associated tuberculosis co-infected patients in Phnom Penh City. The isolates of M. tuberculosis were collected during active laboratory-based surveillance. Of the 98 isolates studied, M. tuberculosis resistance to isoniazid was seen in 23.5%, resistance to rifampicin was seen in 16.3% and multidrug-resistance (MDR-TB) was seen in 5.1%. Our findings reveal an alarmingly high level of resistance to isoniazid and rifampicin, and confirms the need for drug susceptibility testing to guide treatment in patients with culture positive tuberculosis.
