Dysosmia and dysgeusia in patients with COVID-19 in northern Taiwan.

BACKGROUND/PURPOSE: To investigate the characteristics of dysosmia and dysgeusia among patients diagnosed with coronavirus disease 2019 (COVID-19) in Taiwan. METHODS: Prospective data collection between January 22, 2020 to May 7, 2020 of nucleic acid confirmed COVID-19 hospitalized patients in northern Taiwan by the Taiwan Centers for Disease Control were analyzed. RESULTS: Of 217 patients enrolled, 78 (35.9%) reported dysosmia (n = 73, 33.6%) and/or dysgeusia (n = 62, 28.6%). The median duration of COVID-19 associated symptom-onset to development of dysosmia and/or dysgeusia was <1 days (interquartile range [IQR], <1-6 days) and 53 of 78 (67.9%) patients developed dysosmia and/or dysgeusia as one of the initial symptoms of COVID-19. Of 59 closely monitored patients, 41 (69.5%) patients recovered within 3 weeks after symptoms onset and the median time to recovery was 12 days (IQR, 7-20 days). Only 6 of the 59 (10.2%) patients reported persistent dysosmia and/or dysgeusia before discharge from hospitals. Multivariate analysis showed that younger individuals (adjusted hazard ratio [AHR], 0.93 per one-year increase; 95% confidence interval [95% CI], 0.89-0.97; P = 0.001), women (AHR, 2.76; 95% CI, 1.05-7.25; P = 0.04) and travel to North America (AHR, 2.35; 95% CI, 1.05-5.26; P = 0.04) were the significant factors associated with dysosmia and/or dysgeusia. CONCLUSION: Dysosmia and/or dysgeusia are common symptoms and clues for the diagnosis of COVID-19, particularly in the early stage of the disease. Physicians should be alerted to these symptoms to make timely diagnosis and management for COVID-19 to limit spread.

Voluntary counseling and testing among post-partum women in Botswana.

OBJECTIVE: To determine uptake and socio-demographics predictors of acceptance of voluntary counseling and testing (VCT) among post-partum women in Botswana. METHODS: Women attending maternal and child health clinics for their first post-partum or well baby visit in three sites in Botswana were offered VCT after a written informed consent. A standardized questionnaire was used to collect socio-demographic characteristics and reasons for declining VCT. RESULTS: From March 1999 to November 2000, we approached 1735 post-partum women. Only 937 (54%) of those approached accepted VCT. In multiple logistic regression analysis, younger maternal age, not being married, and less formal education were significant predictors of acceptance of VCT. Thirty percent of women who accepted VCT were HIV-positive. CONCLUSION: Our results indicated that in Botswana prior to the initiation of a government Mother to Child Transmission (MTCT) prevention program, younger, unmarried, and less educated post-partum women were more likely to undergo VCT. PRACTICE IMPLICATIONS: Our results have shown that interventions to improve VCT among post-partum women and more generally among women of reproductive age are warranted in Botswana. These interventions should account for differences such age, marital status, education, and partner involvement to maximize VCT uptake.

Comparative prediction of perinatal human immunodeficiency virus type 1 transmission, using multiple virus load markers.

Maternal plasma human immunodeficiency virus (HIV) type 1 RNA load has a role in perinatal transmission, but significant overlap in the range of plasma virus loads among transmitters and nontransmitters is often observed, which makes it difficult to predict transmission outcome. We measured several virus markers in a drug-naive population of HIV-1-infected mothers in Botswana. Maternal plasma HIV-1 RNA load, peripheral blood mononuclear cell-associated blood HIV-1 DNA load, and cervicovaginal fluid (CVF) HIV-1 DNA load were determined using quantitative real-time polymerase chain reaction. The overall rate of transmission among these mother-infant pairs was 35.7%. Median infant age was 2.5 months. An association between increased plasma HIV-1 RNA load and perinatal transmission was observed (odds ratio [OR], 2.20/1-log virus load; 95% confidence interval [CI], 1.15-4.18). However, the association between increased blood HIV-1 DNA load and perinatal transmission was stronger (OR, 10.30; 95% CI, 2.11-50.38). When blood HIV-1 DNA load was combined with CVF HIV-1 DNA load, the association with transmission increased (OR, 25.0; 95% CI 2.73-228.60).
