RESUMEN
BACKGROUND: International travel is among the leading impactful factors of COVID-19 transmission; thus, adequate knowledge, good attitude and good preventive practices toward COVID-19 for international travelers are particularly essential for successful pandemic control. METHODS: A cross-sectional, questionnaire-based study was conducted to determine knowledge, attitude and practices (KAP) of international travelers (both Thai and non-Thai) and expatriates in Thailand. The data were collected at the Thai Travel Clinic, Bangkok, Thailand and via online platforms during May to October 2020. The independent T-test, Chi-square test and multiple regression analysis (MRA) were applied to determine factors influencing the KAP. RESULTS: Of 399 travelers, 46.6% were male, 72.1% had a Bachelor's degree or higher, and the mean age was 35.6 ± 9.6 years. Due to unexpected travel restrictions and lock down, 77.9% of participants were Thai and the respective major purpose of travel was business/work. Travel cancellation/postponement was reported at 73.9%. While sufficient knowledge (≥ 60% correct answers) was reported in 77.9% of participants, a low percentage of correct answers was found in the questions regarding disease transmission. The travelers reported a neutral attitude and an overall moderate concern regarding the COVID-19 situation. Adequate preventive practices were determined by the average practice score 3.54 ± 0.38 (0 = never and 4 = always). The MRA revealed that the factors influencing good practices were travelers who: i) enrolled from outside the hospital (online platform); ii) received pretravel advice at hospital; iii) were female; iv) participated before the declaration of the end of the outbreak; v) were aged 40-49 years, and vi) visited friends and relatives. CONCLUSIONS: The majority of travelers in this study had sufficient knowledge, a neutral attitude and adequate preventive practices toward COVID-19. The factors influencing good practices included pretravel advice, sex, age and the point in the timeline of the outbreak. In order to better control the COVID-19 pandemic situation, pretravel counselling and advice should be promoted as a means to improve knowledge, particularly in disease transmission, increase awareness and emphasize appropriate preventive measures toward COVID-19 among international travelers. Furthermore, preventive practices should be bolstered at all times regardless of the outbreak situation.
RESUMEN
Our cross-sectional study estimated the prevalence and clinical relevance of hypokalaemia among confirmed COVID-19 cases admitted in three hospitals in Bangkok during the early outbreak in Thailand. Of 36 patients, nine were in the hypokalaemia group (25%) and 27 in the normokalaemia group (75%). All cases were asymptomatic, and 94.4% had mild hypokalaemia. Hypokalaemia was found significantly earlier in the course of COVID-19 without evidence of significant extrarenal potassium loss. Body temperature and mean serum sodium in the hypokalaemia group tended to be higher than the normokalaemia group. Hypokalaemia and potentially higher serum sodium among COVID-19 patients were the remarkable findings. This issue warrants for further investigation.

We report a young Thai man from the Thai-Myanmar border suffering from 2 days of fever and myalgia without respiratory tract signs or symptoms. He reported no history of travel through an area with confirmed COVID-19 cases or contact with sick persons. After excluding malaria and dengue, which are common causative agents of acute undifferentiated febrile illness (AUFI) in Thailand, chest radiography was performed according to the patient triage protocol of our institute for AUFI during the COVID-19 outbreak. Chest radiography revealed findings compatible with pneumonia. Nasopharyngeal, throat, and sputum samples tested positive for SARS-CoV-2 by real-time reverse transcriptase-PCR. The preadmission diagnosis of COVID-19 in this patient enabled appropriate management and isolation to prevent nosocomial transmission. Fever and nonspecific symptoms and laboratory results in early COVID-19 may be difficult to distinguish from tropical infectious diseases, especially when respiratory signs and symptoms are absent. This fact necessitates vigilant awareness in clinical investigation, management, and infection control, especially in tropical resource-limited settings.
