Timely detection of novel coronavirus (2019-nCoV) infection cases is crucial to interrupt the spread of this virus. We assessed the required expertise and capacity for molecular detection of 2019-nC...oV in specialised laboratories in 30 European Union/European Economic Area (EU/EEA) countries. Thirty-eight laboratories in 24 EU/EEA countries had diagnostic tests available by 29 January 2020. A coverage of all EU/EEA countries was expected by mid-February. Availability of primers/probes, positive controls and personnel were main implementation barriers.

There are currently 4 different serotypes of Dengue virus known to science. Each time someone get infected and recovers, the individual will be protected by a lifelong immunity from further infection...> against that specific serotype and that serotype only.
Consequent infection from different serotype not only will infect the individual but may also cause a more serious or severe disease progression.

Rabies is a fatal viral disease, but is preventable in humans. The rabies virus is transmitted to humans through virus-laden saliva from a rabid animal, mostly dogs. The ...ighlight medbox">virus is shed in the saliva of an infected animal and can be introduced into another body through bites, scratches and any other wounds that transect the skin. Contact of the infected saliva with mucous membranes is also thought to be a possible route of infection, whereas contact of infected saliva with intact skin is not considered an exposure. Rabies is preventable through pre-exposure prophylaxis (PrEP) for individuals at high and continual risk, and post-exposure prophylaxis (PEP).

Mpox is an emerging zoonotic disease caused by the mpox virus, a member of the Orthopoxvirus genus closely related to the variola virus that causes smallpox. Mpox was first discovered in 1958 when o...utbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was recorded in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox and since then the infection has been reported in a number of African countries. Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA. Two separate clades of the mpox virus are currently circulating in Africa: Clade I, which includes subclades Ia and Ib, and Clade II, comprising subclades IIa and IIb. Clade Ia and Clade Ib have been associated with ongoing human-to-human transmission and are presently responsible for outbreaks in the Democratic Republic of the Congo (DRC), while Clade Ib is also contributing to outbreaks in Burundi and other countries.
In 2022‒2023 mpox caused a global outbreak in over 110 countries, most of which had no previous history of the disease, primarily driven by human-to-human transmission of clade II through sexual contact. In just over a year, over 90,000 cases and 150 deaths were reported to the WHO. For the second time since 2022, mpox has been declared a global health emergency as the virus spreads rapidly across the African continent. On 13 Aug 2024, Africa CDC declared the ongoing mpox outbreak a Public Health Emergency of Continental Security (PHECS), marking the first such declaration by the agency since its inception in 2017.7 This declaration empowered the Africa CDC to lead and coordinate responses to the mpox outbreak across affected African countries. On August 14, 2024, the WHO declared the resurgence of mpox a Public Health Emergency of International Concern (PHEIC) emphasizing the need for coordinated international response.
As of August 2024, Mpox has expanded beyond its traditional endemic regions, with new cases reported in countries including Sweden, Thailand, the Philippines, and Pakistan. Sweden has confirmed its first case of Clade 1 variant, which has been rapidly spreading in Africa, particularly in DRC. The emergence of this new variant raises concerns about its potential for higher lethality and transmission rates outside Africa.

Human strongyloidiasis is a chronic parasitic disease caused by infection with Strongyloides stercoralis, a soil-transmitted helminth that is estimated to infect 300–600 million people worldwide. This neglected tropical disease (NTD) is endemic gl...obally, predominately in the South-East Asia, African and Western Pacific regions, and in South and Central America. Strongyloidiasis has a wide range of clinical presentations, including subclinical disease, symptomatic disease (often with diarrhoea, abdominal pain and urticaria) and a rare but deadly complication of hyperinfection with disseminated disease. The feared complication of disseminated strongyloidiasis can occur in the setting of immunocompromising conditions (e.g. human T-cell lymphotropic virus type 1 infection and malignancies) or immunosuppressive medications (e.g. steroids) and has an estimated case-fatality rate exceeding 60%. The standard treatment for chronic S. stercoralis infection is oral medication with ivermectin.

COVID-19, a disease caused by a novel corona virus (SARS CoV-2), is currently a pandemic, which produces high morbidity in the elderly and in patients with associated comorbidities. Chronic kidney disease stage-5 (CKD-5) patients on dialysis [mainte...nance hemodialysis (MHD)or continuous ambulatory peritoneal dialysis (CAPD)] are also vulnerable group because of their existing comorbidities, repeated unavoidable exposure to hospital environment and immunosuppressed state due to CKD-5. These patients are therefore not only more prone to acquire infection but also develop severe diseases as compared to general population.

Le développement d’une immunité face à un agent pathogène à la suite d’une infection naturelle comporte plusieurs étapes et prend généralement une à deux semaines. Une ...="attribute-to-highlight medbox">infection virale entraîne immédiatement une réponse immunitaire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.

Dengue fever is a mosquito-borne tropical disease caused by the dengue ...hlight medbox">virus. Symptoms typically begin three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.

In the Indian state of Bihar, visceral leishmaniasis (VL) is a major public health issue that has been aggravated by the rising incidence of new Human immunodeficiency virus (HIV) infections. In end...emic areas, the risk of VL infections in patients living with HIV (PLHIV) is higher. It is important to investigate the disease-related knowledge, attitude, and practices (KAP) of PLHIV in Bihar in order to monitor HIV/VL co-infection. Adequate knowledge, a positive attitude, and good practices for VL control are essential to stamp out the disease. This study investigated the KAP towards VL in HIV patients attending antiretroviral therapy (ART) clinic at ICMR-RMRIMS, Patna.
