Summary
Rotavirus (RV) poses a waterborne disease risk. This study found RV in rural Goiás water sources was significantly more prevalent during the dry season compared to the rainy season.
Area of Science:
- Environmental microbiology
- Public health virology
- Water quality assessment
Background:
- Rotavirus (RV) is a primary cause of waterborne diseases and recognized by WHO as a potential reference pathogen.
- Contaminated water sources pose significant public health risks, leading to outbreaks and epidemics.
Purpose of the Study:
- To detect and correlate the presence of Rotavirus in rural water sources in Goiás.
- To investigate the seasonal prevalence of Rotavirus in drinking water during dry and rainy periods.
Main Methods:
- Collection of 86 water samples during the dry season and 160 during the rainy season from rural Goiás.
- Concentration of water samples, extraction of viral genetic material, and application of molecular testing.
- Statistical analysis to determine the association between Rotavirus presence and season.
Main Results:
- Rotavirus was detected in 54.7% of samples during the dry season and 20% during the rainy season.
- A strong statistical association (p-value < 0.001) was found between Rotavirus presence and the dry season.
- The dry season showed significantly higher Rotavirus prevalence in the studied water sources.
Conclusions:
- Rotavirus contamination in rural water sources in Goiás is significantly associated with the dry season.
- Findings highlight the need for enhanced water safety measures, particularly during dry periods, to mitigate risks of waterborne diseases.
- Seasonal monitoring of Rotavirus in drinking water is crucial for public health protection in endemic areas.

01:19Quality of Water
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:25Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
01:17Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
