The disease is a bacterial infection transmitted mainly by ticks. A fever after exposure deserves a review, even without memory of a bite. Is the absence of recovered tick sufficient to exclude exposure? No: Many sick people don't remember a shot. The activities and places visited remain relevant to the assessment. Anaplasma phagocytophilum
Review of the sensitivity of a bacterium to antibiotics to contribute to the therapeutic choice with the clinical context.
Ability of bacteria to resist antibiotics. It's the micro-organism that becomes resistant, not the person.
Antibiorésistance et résistance aux antimicrobiens : mécanismes, surveillance, prévention des infections et bon usage des traitements. Résistance : lire le chiffre avant de le comparer. La résistance concerne les micro-organismes. Dans sa fiche de juillet 2026, l’OMS indique qu’environ une infection bactérienne confirmée en laboratoire sur six dans le monde était résistante aux antibiotiques en 2023. Ce repère ne représente pas la fréquence de résistance chez toutes les personnes.
Medicinal product for certain bacterial infections. It does not treat a viral infection; its indication is a medical evaluation.
Distinguer les familles d’antimicrobiens, comprendre la résistance et préparer les questions utiles sur une prescription sans choisir soi-même un traitement. Quatre familles, des cibles différentes. Antimicrobien est le terme général. L’antibiotique en est une catégorie : il vise les bactéries. La catégorie du médicament ne suffit toutefois pas à déterminer le traitement d’une personne.
Family of drugs for micro-organisms: antibiotics, antivirals, antifungals or antiparasitic medicines. The term does not refer to a single treatment.
Medicinal product targeting a virus in specific indications. An antiviral is not interchangeable with an antibiotic.
Aspergillus is an environmental mould. Exposure does not automatically mean aspergillosis. Is the aspergillosis usually transmitted between people? No. The acquisition is mainly environmental by inhalation of spores. The measures concern exposures and the medical field. Aspergillus spp.
Babesiosis is a parasitism of red blood cells, transmitted mainly by ticks. It can also be acquired through contaminated transfusion. Is she passing on like a cold between relatives? No: Ordinary contacts are not the usual transmission. Injections, transfusions and some maternal transmissions are distinct contexts. Babesia spp.
The bacterial category includes respiratory, digestive, vector-borne or wound-related infections. Tuberculosis, listeriosis and tetanus illustrate three different mechanisms. The relevant measures must relate the agent to its context, rather than treating all bacteria as an identical hazard.
Campylobacteriosis is a digestive infection often associated with contaminated foods, including undercooked poultry. Water and raw milk may also be involved. Do we still need antibiotics? No: Management is often based on rehydration. Antibiotics are reserved for certain medically evaluated situations, including invasive infections; diarrhoea alone is not enough to decide them. Campylobacter spp.
Candidiasis occurs when Candida, a yeast naturally present in the body, proliferates. Local infection and invasive candidiasis are different situations. Does the common candidiasis behave like Candida auris? No: Candida auris has special features, including spread in health care facilities. Information on this species should not be automatically applied to a typical local candidiasis. Candida spp.
This catalogue label is a documentary context, not a channel of transmission. It brings together sheets whose mechanisms or rarity require a specific reading. The number of entries here is neither an impact nor an alert level.
La température limite la multiplication de nombreux microorganismes sans les supprimer. Achat, transport, rangement, ouverture du réfrigérateur et panne électrique forment une seule chaîne : chaque rupture raccourcit la marge de sécurité. Mesurer au bon endroit, noter le bon moment. Le réglage du réfrigérateur ne suffit pas à connaître la température des aliments. Les zones varient selon l’appareil ; sa notice indique leur organisation. L’étiquette du produit précise les conditions qui lui sont propres.
Fungal infections in the repertoire cover superficial and invasive diseases. Some are associated with an environment, others are associated with a flora already present or with a transmission in care. A mould visible in a dwelling does not diagnose a fungus in a person.
Chikungunya is an infection transmitted by Aedes mosquitoes, often marked by severe joint pain. Do persistent pains prove that the virus is still circulating in the blood? No. They can prolong the disease without translating the same phase of infection. Monitoring is useful if it limits activities. Virus chikungunya
Lymphocytic choriomeningitis is a viral infection associated with mice and their dejections. It may sometimes evolve to a neurological condition. Are domestic rodents always safe? No: Domestic mice or hamsters may be infected. Their origin and contact with wild rodents should be considered, without assigning any disease to the animal. Lymphocyte choriomeningitis virus
Chromoblastomycosis is a subcutaneous fungal infection acquired after an injury exposed to environmental fungi. It often evolves slowly. Does this infection go directly from one person to another? No: WHO describes inoculation from the environment after an injury. Mosquitoes are not its vector. Mushrooms, dematiacated
Pertussis is a bacterial respiratory infection. A persistent cough may exist without the characteristic song. Can a vaccinated person still have a whooping cough? Yes. Protection decreases over time; symptoms may be less typical. Report a persistent cough before you meet an infant. Bordetella pertussis
COVID-19 is an infection with SARS-CoV-2. A mild form may resemble other respiratory infections. Does a positive PCR measure the infectiousness exactly? No. Detection of a genetic target may persist; its interpretation depends on time, symptoms and context. SARS-CoV-2
Dengue is mainly transmitted by infected Aedes mosquitoes. Their presence alone does not demonstrate local transmission. What are the signs of urgent care? Significant abdominal pain, persistent vomiting, bleeding or high weakness after fever require urgent assessment. Avoid aspirin and ibuprofen if dengue is suspected. Dengue virus Dengue : la baisse de la fièvre ne suffit pas à rassurer. Des signes d’alerte peuvent apparaître lorsque la fièvre diminue. Une douleur abdominale importante, des vomissements répétés ou un saignement demandent une évaluation urgente.
Echinococcus is associated with ingestion of Echinococcus parasite eggs. Cystic and alveolar forms can evolve for years without visible signs. Does a cyst always have to be operated? No: The strategy depends on its stage and the situation. WHO describes several options, including monitoring in some cases. The decision is a matter for a competent team. Echinococcus spp.
Ehrlichiosis are bacterial infections transmitted mainly by ticks. They can produce febrile syndrome and sometimes severe illness. Should we wait for confirmation before any treatment? The CDC recommends that clinical suspicion should be started while waiting for examinations. This is the decision of the professional, according to the exhibition and the picture. Ehrlichia spp.
