COVID-19 mortality in Brazil

Area of Science:

  • Epidemiology
  • Public Health
  • Infectious Diseases

Background:

  • COVID-19 disproportionately affects vulnerable populations in Brazil.
  • Traditional communities face health disparities, increasing severe COVID-19 outcomes.
  • Identifying mortality factors in these groups is crucial for targeted interventions.

Purpose of the Study:

  • To identify factors associated with COVID-19 mortality.
  • Focus on hospitalized patients from traditional communities in Brazil.

Main Methods:

  • Cross-sectional study of COVID-19 hospitalizations (2021-2023).
  • Data from the System of Epidemiological Surveillance of Influenza (SIVEP-Gripe).
  • Logistic regression analysis of demographic, clinical, and comorbidity data.

Main Results:

  • Male sex, older age, Black, and Indigenous ethnicity increased mortality risk.
  • Dyspnea, low oxygen saturation, immunosuppression, and chronic renal disease were risk factors.
  • Invasive ventilation (OR=19.4) posed the highest mortality risk.

Conclusions:

  • Male sex, older age, race/color, severe respiratory symptoms, comorbidities, and invasive ventilation are key mortality predictors.
  • Findings highlight the need for targeted health strategies for vulnerable populations.
  • Reducing COVID-19 mortality in traditional communities requires focused public health efforts.

Factors Affecting Illness01:18

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Lifestyle Factors and Health

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
