“…In Cuba, Giardia infection in children has been widely reported (Nú ñ ez et al, 1999(Nú ñ ez et al, , 2003bMendoza et al, 2001Mendoza et al, , 2003Escobedo et al, 2007) but data on the epidemiology of, and disease burden posed by, symptomatic giardiasis in paediatric patients is scarce. The aim of the present study was to identify the risk factors associated with Giardia infection in hospitalized children in the city of Havana.…”

The risk factors associated with Giardia infection, in children hospitalized in Havana, Cuba, were recently explored. Children aged >5 years were more likely to be positive for Giardia infection than the younger children, with an odds ratio (OR) of 3.41 [95% confidence interval (CI)51.36-9.69]. The risk factors found to be associated with Giardia infection in univariate analyses were rural residence (OR53.01; CI51.23-7.35), belonging to a household that did not receive water from an aqueduct (OR53.27; CI51.21-8.91), drinking unboiled water (OR53.64; CI52.14-6.26), nail biting (OR53.47; CI51.97-6.08), eating unwashed vegetables raw (OR54.84; CI52.33-10.14), and a personal (OR53.23; CI51.58-6.59) or family history (OR53.96; CI51.53-10.47) of previous parasitic infection. In multivariate analyses, however, only two (modifiable) risk factors were found to be independently and significantly associated with Giardia infection: nail biting and eating unwashed vegetables raw. It therefore seems that, at least at the individual level, giardiasis-prevention activities in Havana should be focussed on health education to improve personal hygiene and food-related practices. If appropriately managed, the surveillance of drinking water and foodstuffs, for Giardia and other parasites, might also help to reduce the hospitalization of Cuban children.

“…For instance, Cañete et al, reported a prevalence above 38% among children who were attended to in a day care center in an urban area of Matanzas city [19]. In a cross-sectional study carried out by Escobedo et al, to determine the prevalence of intestinal parasitic infections among children at educational centers in a rural area of San Juan y Martinez, Pinar del Rio province, they found the same data of prevalence of Blastocystis [20] as were found by the researchers in the Matanzas study. On the other hand, in the second national survey of intestinal parasitic infections in Cuba, in which samples of all age groups were collected, the frequency of this protozoan was 8.89% [12].…”

Blastocystis sp. is one of the most common intestinal parasites diagnosed worldwide, but its pathogenic role is still regarded by some authors as controversial. The frequency of Blastocystis sp. was studied during a two year period of time and its association with some clinical symptoms. An observational descriptive study was carried out from January 2012 to December 2013. A total of 3140 stool samples were investigated for the presence of parasites by various parasitological techniques. Among 3140 analyzed stool samples the prevalence of Blastocystis infection observed was 3.54%, the fourth most prevalent. A total of 111 stool samples were positive for Blastocystis sp., and 71 samples showed co-infection with one or more other intestinal parasites. The group of 5 to 14 years age group showed a higher percentage of infections in the group of symptomatic persons than in asymptomatic ones and it was statistically significant, while in persons with ages more than 40 years the frequency of infection with this parasite was higher in asymptomatic persons. Blastocystis infection is one of the most frequent parasitic infections diagnosed in our setting. The relationship with symptomatology found in individuals infected with Blastocystis was significant and this association was higher in younger children.

“…When the awareness of Giardia infection among caregivers in Havana, 33,34 its increased prevalence among children, [3][4][5][6][7][8][9] and its occurrence within the community, 2 which may also be a cause of hospitalization, 35,36 are considered, it is not surprising to find that children of mothers who knew other people with Giardia were diagnosed earlier. However, it seems that despite efforts at informing the public about intestinal parasites in Cuba, more information is necessary for addressing the giardiasis.…”

“…1 In Cuba, in the last national survey carried out in 2009, the overall prevalence of Giardia in human population was estimated to be 6.02%; 2 however, higher prevalences have been recorded among young children attending day-care centres 3,4 and primary schools, 5,6 and, according to hospital-based studies, it seems to be that clinical giardiasis is a common reason for hospitalization in paediatric hospitals. [7][8][9] As in other diseases, the diagnosis of giardiasis critically depends on the community's perception of the disease, care-seeking behaviour of individuals, socio-economic factor, and the suspicion index of the health care providers.…”

Giardiasis is one of the commonest intestinal parasitic infections in Cuba. In order to determine careseeking behaviour and diagnostic processes in paediatric in-patients with giardiasis, structured questionnaires were administered by interview mothers of children with giardiasis during January to December 2010. During the study period, 97 children were diagnosed with giardiasis, of whom 86 (88.6%) caregivers were interviewed. The median number of days from symptoms onset to the first presentation in a health unit was 2 days (range: 0-15 days). The pattern of care-seeking behaviour was variable; 41 (47.7%) of children initially visited the emergency unit in a paediatric hospital. Sixty-six children had, at least, one further contact for help before diagnosis of giardiasis was made (range: 1-5 contacts) and of the 128 contact visits, 94 (73.4%) were also targeted more to hospitals. There was a median time of 6 days between the first presentation to a health unit until diagnosis, which was mainly made by microscopic examination of duodenal aspiration. Among factors investigated in mothers, only knowing other person with giardiasis had significant association with their ability to suspect giardiasis [odds ratio (OR): 29.8, 95% confidence interval (CI): 3.71-239.4, P50.001]. Requesting a faecal specimen or ordering duodenal aspiration for microscopic examination during the first visit appeared associated with correct diagnosis (OR: 3.84, 95% CI: 1.57-9.40, P50.003). Efforts should be made to increase doctors' awareness of-and diagnostic skills for childhood giardiasis. At the same time, it is necessary to improve caregivers' awareness about giardiasis.
