Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Sexually Transmitted Infections

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Controls in Experiments

Controls in Experiments

When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Pulmonary Tuberculosis IV

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Area of Science:

Public Health
Epidemiology
Infectious Diseases

Background:

The COVID-19 pandemic presents a substantial challenge to global health systems, including Sudan.
Sudan reported its first COVID-19 case on March 13, 2020.
As of November 11, 2020, Sudan recorded 14,401 confirmed cases.

Purpose of the Study:

To analyze the epidemiological situation of COVID-19 in Sudan.
To evaluate the effectiveness of implemented preventive and control measures.
To identify factors contributing to the continued emergence of new cases.

Main Methods:

Descriptive epidemiological analysis of reported COVID-19 cases in Sudan.
Review of implemented public health interventions.
Assessment of case fatality rate and recovery statistics.

Main Results:

By November 11, 2020, 1,116 deaths were reported, yielding a case fatality rate of 7.7%.
Out of 14,401 confirmed cases, 9,535 recovered, and 3,750 were under treatment.
Despite control measures like partial lockdown and social distancing, new cases continue to emerge.

Conclusions:

The COVID-19 pandemic poses a significant threat to Sudan's health system.
A high case fatality rate suggests challenges in managing the pandemic.
Non-compliance with preventive measures is a likely driver for ongoing transmission.
