Stages of Infection

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Classification of Illness

Classification of Illness

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Steps in Outbreak Investigation

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Pulmonary Tuberculosis II

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Area of Science:

Epidemiology
Biostatistics
Public Health

Background:

Despite vaccination, several countries face significant COVID-19 waves.
Accurate short-term forecasting of cases and fatalities is essential for healthcare management.

Purpose of the Study:

To develop a reliable statistical method for real-time, short-term forecasting of COVID-19 cases and deaths.
To specifically address the needs of 'latecomer' countries in their pandemic response.

Main Methods:

Utilized a penalized LASSO regression model incorporating an error correction mechanism.
Modeled latecomer countries based on countries at similar pandemic stages previously.
Employed an adaptive rolling-window scheme for forecasting.

Main Results:

The proposed methodology demonstrated strong performance across 45 countries.
Detailed analysis for Brazil, Chile, Mexico, and Portugal confirmed its effectiveness.
The model significantly outperformed alternative forecasting methods.

Conclusions:

The penalized LASSO regression with error correction provides accurate short-term forecasts for COVID-19.
This approach aids in better short-run healthcare system management.
The framework is adaptable for regional forecasting and other infectious diseases.
