Dengue fever is considered as an emerging disease in Afghanistan. Since the first outbreak was reported in 2019, other outbreaks have been reported in the following years. The current study aims to describe the epidemiological features and clinical manifestations of suspected and confirmed cases of dengue fever detected by the National Disease Surveillance and Response (NDSR) Department of the Ministry of Public Health (MoPH) during 2021 and 2022 to prevent further spread and minimize its impact on the country's health system and on the limited number of health workers.

This study, performed in Ottawa, Canada, identifies a decrease in SARS-CoV-2 wastewater measurements during snowmelt-induced sewer flushing events. Observations first revealed a correlation between suppressed viral measurements and periods of increased sewage flowrates, air temperatures above 0 °C during winter months, and solids mass flux increases.

- In Afghanistan, it's hard to provide health care for everyone because of the country's tough geography and cultural issues regarding gender.
- A study collected information on health services and areas that need help by looking at available reports and data from organizations like the World Health Organization.
- Even though there are 4,242 health care centers, many people, especially in rural areas, can't get the care they need, with about 25% of the population underserved, including many women and young children.
Article Synopsis
- The study investigates the decay patterns of SARS-CoV-2 and Pepper mild mottle virus (PMMoV) in wastewater contaminated with stool samples from COVID-19 patients, aiming to reflect real-world conditions better than traditional laboratory methods.
- It examines how these viruses decay under two specific sewer transport conditions—dynamic suspended transport and bed/near-bed transport—across varying temperatures (4°C, 12°C, and 20°C).
- Results show no significant decay of SARS-CoV-2 or PMMoV in dynamic suspended transport over 35 hours, while significant decay occurs in bed/near-bed conditions, especially for PMMoV, which shows higher decay rates at elevated temperatures.
