Influenza is a contagious respiratory illness caused by influenza viruses. Antigenic shift and drift lead to new viral strains and seasonal flu. Transmission occurs via droplets, direct contact, or surfaces. Vaccination and good hygiene are recommended for prevention. Antiviral drugs can reduce symptoms but are best taken within 48 hours of symptoms. High risk groups like young children, elderly, and pregnant women should get the flu shot annually.
Impetigo is a contagious skin infection most common in children ages 2-5 caused by Staphylococcus and Streptococcus bacteria. It causes red sores that rupture and develop a honey-colored crust. It spreads through direct contact with infected skin or surfaces. There are two main types: non-bullous impetigo features small blisters that scab over, usually on the face; and bullous impetigo features fragile fluid-filled blisters due to a bacterial toxin, often on the trunk. Diagnosis is usually clinical but cultures can identify the bacteria. Treatment involves antibiotics either topically or orally depending on severity.

This document discusses the epidemiology of tuberculosis. It begins by defining tuberculosis and how it is transmitted. Globally, the mortality and prevalence of TB is highest in India, which accounts for 20% of global cases. Key epidemiological factors that influence the spread of TB are the bacterial agent, host susceptibility, and social determinants. TB is typically transmitted through droplets in the air and has an incubation period of weeks to years. While pulmonary TB is most common, extrapulmonary TB can also occur. Despite prevention and control efforts like BCG vaccination and India's Revised National Tuberculosis Control Programme, TB remains a major public health challenge in India due to ongoing issues with awareness and socioeconomic factors.

This foreword discusses the author's experience learning about software testing over time. Initially, the author felt uncertainty as their approach to testing own programs differed from what was described in books. The author went through phases of thinking they needed to radically change their approach, then seeing how other approaches worked but not adopting them fully, and finally feeling other approaches wouldn't work for their daily work. The author learned to trust their own experience and judgment over time, as preferences emerge from constantly dealing with testing issues through experience in projects, discussions, trial and error. The author now prefers finding bugs to retesting functions after each change.

Coronavirus disease 2019 detection using deep features learningIJECEIAES
A Coronavirus disease 2019 (COVID-19) pandemic detection considers a critical and challenging task for the medical practitioner. The coronavirus disease spread so rapidly between people and infected more than one hundred and seventy million people worldwide. For this reason, it is necessary to detect infected people with coronavirus and take action to prevent virus spread. In this study, a COVID-19 classification methodology was adopted to detect infected people using computed tomography (CT) images. Deep learning was applied to recognize COVID-19 infected cases for different patients by employing deep features. This methodology can be beneficial for medical practitioners to diagnose infected patients. The results were based on a new data collection named BasrahDataset that includes different CT scan videos for Iraqi patients. The proposed system gave promised results with a 99% F1-score for detecting COVID-19.
Application of ordinal logistic=China.pdfHenokBuno
This study aimed to identify determinants of illness severity for COVID-19 patients in China. Medical records from 598 COVID-19 patients admitted to four hospitals in China between January and March 2020 were analyzed. Patients were divided into moderate (n=400), severe (n=85), and critical (n=113) illness groups based on their condition. Ordinal logistic regression was used to identify predictors of more severe illness. The analysis found that older age, hypertension, abnormal liver enzymes and cardiac markers, longer time from illness onset to diagnosis and admission were associated with increased risk of more severe illness.
This document summarizes several studies on urinary tract infections (UTIs) in India:
- A multicenter study found a 10.1% prevalence of UTIs among outpatients in four regions of India, with females more affected than males. Common risk factors were prior UTIs and diabetes. E. coli and K. pneumoniae caused most infections. Antibiotics showed high resistance.
- Other regional Indian studies found prevalence rates ranging from 6-18% and identified E. coli as the most common cause. Antibiotics resistance was increasing, especially to beta-lactams and fluoroquinolones.
- Studies evaluated UTIs among different age groups and found the highest prevalence in women
Background & objectives: In Odisha, several cases of dengue virus infection were detected for the first time in 2010, the importance of dengue as a serious mosquito-borne viral infection was felt only in 2011 with the reporting of many more positive cases. This retrospective three year study was done to find out the seroprevalence of dengue Igm antibody and to know the predominant serotype of dengue virus among the patients suspected to have dengue virus infection in a tertiary care hospital in southern Odisha, India.
Methods: Blood samples from clinically suspected dengue cases admitted in the Medicine and Paediatrics departments of a tertiary care hospital were collected. These were processed for detection of dengue specific IgM antibody, carried out by the ELISA method. Dengue IgM antibody positive serum samples were tested for serotypic identification.
Results: of the 5102 samples tested, 1074 (21.05 %) were positive for dengue IgM. Maximum numbers of cases were found in 2012. Majority (47.86 %) of cases were detected in the month of September. The most common affected age group was 11 to 20 yr. DENV1 and DENV2 were the detected serotypes.
Interpretation & conclusions: Rapid increase in the dengue cases in 2012 became a public health concern as majority of cases were affecting the young adolescents. Most of the cases were reported in post-monsoon period indicating a need for acceleration of vector control programmes prior to arrival of monsoon.

Hundred samples viz. urine, blood, wound, pus and sputum collected from different patients were found to harbour Pseudomonas aeruginosa (P. aeruginosa) (27%) with a maximum isolation from wound samples (33.33%) and minimum from blood samples (11.11%). The degree of resistance of P. aeruginosa isolates to different antibiotics like Ceftazidime (30µg), Amikacin (30µg), Imipenem (10µg), Ciprofloxacin (30µg), Tetracycline (30µg), Gentamicin (10µg), Norfloxacin (10µg), Penicillin (30µg), Chloramphenicol (30µg), and Ofloxacin (5µg) varied from 56% to 100%. Antiseptics i.e. Betadine and Dettol were found to be more effective against the MDR strain of P. aeruginosa at the dilutions of 10-1 and 10-2. Duration of the disease and hospitalization duration, evaluated as risk factors for P. aeruginosa colonization were found to be statistically significant while age and gender were found to be statistically non- significant. The incidence of multidrug resistance of P. aeruginosa is increasing fast due to the frequent use of antibiotics and antiseptics, which are used extensively in hospitals and healthcare centers, therefore it is a need to develop alternative antimicrobial agents for the treatment of infectious diseases.

Crimean-Congo haemorrhagic fever virus in Kazakhstan (1948-2013)
1) Crimean-Congo haemorrhagic fever virus has been endemic in southern regions of Kazakhstan since the first reported cases in 1948, with over 700 cases reported total through 2013.
2) The disease is seasonal, occurring predominantly between April and June, and is transmitted to humans mainly through tick bites, affecting those in agricultural professions.
3) Case fatality rates have varied between 10-30% depending on the decade, with an overall rate of 14.8% reported.
1. The document summarizes the current state of knowledge about COVID-19, including its origin, pathophysiology, epidemiology, clinical presentation, diagnosis, and management.
2. Key points include that SARS-CoV-2 likely evolved through natural selection in an animal host before transferring to humans, its optimal binding to the human ACE2 receptor, and viral shedding occurring for up to 37 days including in asymptomatic cases.
3. Clinical presentation varies from mild to critical illness, with risk factors for severe disease including older age and comorbidities. Lymphopenia and elevated inflammatory markers are common lab findings.
1) Men with COVID-19 are more at risk for worse outcomes and death compared to women, independent of age. In a case series and public data set of COVID-19 patients, men represented a higher percentage of severe and critical cases as well as deaths.
2) Older age and pre-existing medical conditions were associated with higher severity and mortality for both COVID-19 and SARS patients. However, even after accounting for age and health status, men still had poorer outcomes for both diseases.
3) While men and women were equally likely to be infected with COVID-19 or SARS, male patients experienced higher mortality rates for both viruses.

This study analyzed ticks collected from four vegetation sites in South Korea over two years to understand tick populations and the prevalence of severe fever with thrombocytopenia syndrome virus (SFTSV). The dominant tick species was Haemaphysalis longicornis, which made up over 95% of collected nymphs and adults. H. longicornis nymph numbers peaked in June 2020 while adult numbers peaked in July 2019 and June 2020. Testing found the virus in H. longicornis pools in August-October 2020, with the highest minimum infection rate in August. Most ticks and virus-positive pools were found in grassland and grave sites. The results provide insights into controlling SFTSV risk through tick management

2) Ageing is a natural process, but it brings physical and psychological changes. Geriatrics seeks to understand these changes and support maximum independence for the elderly through treatment, screening, and lifestyle management.
3) A multidisciplinary team approach is often used in geriatrics, involving geriatricians, nurses, physiotherapists, and social workers to address medical, physical, social, and emotional needs of older patients. The goals are to maintain health, detect and manage illnesses early, and provide supportive care during
A 20-year-old Spanish man traveling in Thailand for a martial arts competition was admitted to a local hospital in Koh Samui, Thailand with fever, headache, and decreased consciousness. His condition worsened over 48 hours, developing seizures, paralysis, and decreased responsiveness. Testing revealed positive IgM antibodies for Japanese encephalitis virus (JEV) in his serum. JEV is a mosquito-borne virus that causes viral encephalitis, with high incidence in parts of Asia. Personal protection from mosquito bites and vaccination are recommended for travelers to endemic areas.

GASTROINTESTINAL INFECTIONS AND GASTRITIS
Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort.

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

ABSTRACT
Background: Since 1976, seven outbreaks of hepatitis E occurred in Ahmedabad. Clusters of jaundice cases were reported on
June 19, 2008, by a civic center, Girdharnagar ward, Ahmedabad. Objectives: The objectives were as follows: (1) to identify the
etiological agent, source of outbreak, and mode of transmission; (2) to propose a control measure based on the outbreak investigation.
Materials and Methods: We defined a case as an acute illness with (a) a discrete onset of symptoms and (b) jaundice or elevated
serum aminotransferase levels, from March to September 2008 in the households of the Girdharnagar ward. We collected data
through a door-to-door survey and hospital records. We described the outbreak in terms of time, place, and person. We collected
laboratory investigation reports of case patients admitted to the civil hospital. To test our hypothesis we conducted a retrospective
cohort study to find out the relative risk for hepatitis. We conducted environment investigation to find out the source of
contamination of water supply. Results: A total 233 case patients of hepatitis were identified with the attack rate of 10.9/1000
population. Cases were reported in all the age groups with a higher attack rate in the age group of 20–29 years (18.5/1000). Out of
17 case patients, 16 were positive for the hepatitis E IgM antibody. The attack rate was two times more among those who were
exposed to the leaking pipeline than the non-exposed (RR=2.3, 95% CI 1.76, 2.98). Environmental investigation also confirmed
the sewage contamination of drinking water in the distribution system. Conclusion: The outbreak was due to hepatitis E virus.
We recommended a temporary alternative water supply, repair of the leakages, and water quality surveillance.
