World Neglected Tropical Diseases Day 2024

World Neglected Tropical Diseases Day is observed every year on 30 January

On World Neglected Tropical Disease Day 2024, WHO is calling on everybody, including leaders and communities, to unite and act to address the inequalities that drive neglected tropical diseases (NTDs) and to make bold, sustainable investments to free the estimated 1.62 billion people, in the world’s most vulnerable communities, from a vicious cycle of disease and poverty. 

The purpose of World Neglected Tropical Diseases Day is to raise the profile of neglected tropical diseases, the suffering they cause and to garner support towards their control, elimination and eradication, in line with the programmatic targets set out in the NTD road map 2021−2030 and the commitments of the 2022 Kigali declaration on neglected tropical diseases.

On 31 May 2021, the Seventy-fourth World Health Assembly recognized 30 January as World Neglected Tropical Diseases Day through the unanimous approval of decision WHA74(18)  by WHO Member States. This Day is now one of the 11 Global Health Days and 2 Global Health Weeks recognized by WHO.


Brief summary
World NTD Day 2024

——

Buruli ulcer
A debilitating mycobacterial skin infection causing severe destruction of the skin, bone and soft tissue.

Chagas Disease
A life-threatening protozoan illness transmitted to humans through contact with vector insects (triatomine bugs), ingestion of contaminated food, infected blood transfusions, congenital transmission, organ transplantation or laboratory accidents.

Dengue and chikungunya
Two mosquito-borne, outbreak-prone viral conditions causing a flu-like illness that can be associated with severe, painful and disabling symptoms and, in the case of dengue, may cause shock, haemorrhage and death.

Dracunculiasis (guinea-worm disease)
A helminth infection transmitted exclusively by drinking water contaminated with parasite-infected water fleas; one year later, adult female worms painfully ulcerate through the skin, often of the legs, in order to expel their larvae.

Echinococcosis
A disease caused by the larval stages of tapeworms forming pathogenic cysts in human organs, acquired by ingesting eggs most commonly shed in the faeces of dogs and wild animals.

Foodborne trematodiases
A group of infectious diseases acquired by consuming fish, crustaceans and vegetables contaminated with larval parasites; clonorchiasis, opisthorchiasis, paragonimiasis and fascioliasis are the most common.

Human African trypanosomiasis (sleeping sickness)
A protozoan infection spread by the bites of tsetse flies that is almost 100% fatal without prompt diagnosis and treatment to prevent the parasites from invading the central nervous system.

Leishmaniases
A group of protozoan diseases transmitted through the bites of infected female sandflies; the most severe (visceral) form attacks the internal organs and in its most prevalent (cutaneous) form causes skin ulcers, disfiguring scars and disability.

Leprosy
A complex disease caused by infection with a slow-growing bacterium, mainly affecting the skin, peripheral nerves and eyes.

Lymphatic filariasis (elephantiasis)
A helminth infection transmitted by mosquitoes and resulting in adult worms inhabiting and reproducing in the lymphatic system; it is associated with recurrent painful inflammation and abnormal enlargement of limbs and genitals.

Mycetoma, chromoblastomycosis and other deep mycoses
Chronic, progressively destructive inflammatory diseases of the skin and subcutaneous tissues which usually affect the lower limbs. People become infected when injuries break the skin and allow fungi (and bacteria in the case of mycetoma) to enter the body.

Noma
Severe gangrenous disease of the mouth and face. Its pathogenesis is linked with non-specific bacteria and a range of modifiable risk factors and underlying social determinants. It mainly affects children aged 2−6 years old and is found most commonly among those living in poor communities.

Onchocerciasis (river blindness)
A helminth infection transmitted by the bite of infected blackflies causing severe itching and eye lesions as the adult worm produces larvae eventually leading to visual impairment and permanent blindness.

Rabies
A preventable viral disease transmitted to humans through the bites of infected animals, especially dogs, that is invariably fatal once symptoms develop.

Scabies and other ectoparasitoses
A group of infestations of the skin caused by mites, fleas or lice; scabies occurs when the human itch mite burrows into the upper layer of the skin where it lives and lays its eggs, causing intense itching and rash.

Schistosomiasis (bilharzia)
A group of trematode infections acquired when larval forms released by freshwater snails penetrate human skin during contact with infested water; schistosomiasis is typically associated with liver and urogenital pathology.

Snakebite envenoming
A potentially life-threatening condition caused by toxins injected through the bite of a venomous snake, often responsible for acute medical emergencies. Envenoming can also be caused by having venom sprayed into the eyes by certain species of snakes.

Soil-transmitted helminthiases
Helminth infections transmitted through soil contaminated by human faeces; they cause anaemia, vitamin A deficiency, stunted growth, malnutrition, intestinal obstruction and impaired development.

Taeniasis and cysticercosis
Taeniasis is caused by adult tapeworms in human intestines; cysticercosis results when humans ingest tapeworm eggs that develop as larvae in tissues, including the brain (neurocysticercosis).

Trachoma
A bacterial infection transmitted through direct contact with infectious eye or nasal discharge, and associated with unsafe living conditions and hygiene practices; if left untreated, it causes irreversible corneal opacities and blindness.

Yaws
A chronic, disfiguring bacterial disease affecting mainly the skin and bone. Other endemic treponematoses similar to yaws are also considered NTDs

U.S. – UK Strategic Dialogue on Biological Security

JANUARY 16, 2024

U.S. – UK Strategic Dialogue on Biological Security

The White House

Building on the June 10, 2021 New Atlantic Charter and the June 8, 2023 Atlantic Declaration on Economic Security, the U.S. National Security Council and the UK Cabinet Office announced a new Strategic Dialogue on Biological Security during a launch event today.  

Underpinned by the UK Biological Security Strategy and the U.S. National Biodefense Strategy, this Strategic Dialogue reflects a shared ambition to bolster future heath and economic resilience against a growing and diverse spectrum of biological threats.

The Strategic Dialogue reaffirms both nations’ commitment to increase collaboration in the following ways:

  • Develop a shared understanding of research and development (R&D) needs at the onset of new disease outbreaks, allowing for improved responsiveness by shaping global R&D efforts and supporting early technology assessments.
  • Adopt a One Health approach to biosurveillance and biological threat detection, in support of international efforts to develop stronger and more interconnected global surveillance capabilities.
  • Pursue the development of new tools and methodologies for microbial forensics and attribution.
  • Promote responsible innovation in the biotechnology, health, and life sciences sectors, shaping global norms and standards on biosafety and biosecurity while simultaneously protecting burgeoning bio-economies.
  • Facilitate the development of next-generation vaccines and therapeutics, in line with the 100-Days Mission vision supported by G7 leaders in Carbis Bay in 2021 and reaffirmed at the 2023 G7 Summit in Hiroshima.
  • Strengthen coordination of efforts to counter biological threats, including developing joint measures to address Biological and Toxin Weapons Convention compliance.

National Center for Emerging and Zoonotic Infectious Diseases

The National Center for Emerging and Zoonotic Infectious Diseases is committed to protecting people from domestic and global health threats, including

  • Foodborne illnesses like Salmonella and waterborne illnesses like infections with Naegleria fowleri (the “brain-eating” amoeba).
  • Infections that spread in hospitals and other healthcare settings.
  • Infections that are resistant to antibiotics.
  • Deadly diseases like Ebola and anthrax.
  • Illnesses that affect immigrants, migrants, refugees, and travelers.
  • Diseases caused by contact with animals, like rabies.
  • Diseases spread by mosquitoes, ticks, and fleas, including yellow fever, Lyme disease, and dengue.
  • Diseases new to the United States, like Zika and mpox.

NCEZID’s scientists also do important work that leads to the development of more effective vaccines, therapeutic drugs, and tools to diagnose lesser-known diseases like Crimean-Congo Hemorrhagic Fever virus infections.

During the COVID-19 pandemic, several flagship NCEZID programs—like the Office of Advanced Molecular Detection, the Laboratory Response Network, and the National Healthcare Safety Network—were essential to tracking COVID variants as they emerged across the country, monitoring the quality of healthcare and patient safety, and strengthening efforts to prevent the spread of COVID-19.

About Our Name

Infectious diseases are illnesses caused by germs (such as bacteria, viruses, and fungi) that enter the body, multiply, and can cause an infection.

  • Some infectious diseases are contagious (or communicable), meaning they are capable of spreading from one person to another.
  • Other infectious diseases can be spread by germs carried in air, water, food, or soil. They can also be spread by vectors (like biting insects) or by animals to humans.

Emerging means infections that have increased recently or are threatening to increase in the near future. These infections could be

  • completely new (like Bourbon virus infection, or MERS, Middle East Respiratory Syndrome).
  • completely new to an area (like chikungunya in Florida).
  • reappearing in an area (like dengue in south Florida and Texas).
  • caused by bacteria that have become resistant to antibiotics, like MRSA (methicillin-resistant Staphylococcus aureus), C. difficile, or drug-resistant TB.

Zoonotic means a disease that is spread between animals and people; some examples include:

  • Lyme disease (spread by ticks).
  • Salmonella (spread by poultry).
  • rabies (spread by mammals).
