infektiös
infektiös em 30 segundos
- Refers to the ability of a disease to spread between organisms.
- Used in medical, clinical, and scientific contexts primarily.
- Can be used metaphorically for emotions like laughter or joy.
- Higher register than the common German word 'ansteckend'.
- Medical Context
- Used to describe pathogens, substances, or patients that can spread biological agents like viruses or bacteria. For example, 'infektiöser Abfall' refers to medical waste that poses a biological hazard.
Während der ersten drei Tage der Erkrankung ist der Patient besonders infektiös.
- Metaphorical Context
- Used to describe emotions, behaviors, or moods that spread quickly among a group of people, such as laughter or enthusiasm. In this sense, it is synonymous with 'captivating' or 'spreading like wildfire'.
Ihr Optimismus wirkte auf das gesamte Team geradezu infektiös.
Das Labor untersucht, wie infektiös die neuen Proben tatsächlich sind.
- Environmental Safety
- In industrial or hospital settings, labels like 'infektiöse Stoffe' are critical for safety protocols to prevent accidental exposure.
Bitte entsorgen Sie alle infektiösen Materialien in den dafür vorgesehenen Behältern.
Die Studie belegt, dass die neue Variante deutlich infektiöser ist als die ursprüngliche.
- Predicative Usage
- The simplest way to use the word is to describe a subject directly. 'Diese Flüssigkeit ist extrem infektiös.' Here, the adjective describes the state of the liquid without needing complex endings.
Man muss vorsichtig sein, da das Virus in dieser Phase besonders infektiös ist.
- Attributive Usage
- When modifying a noun, pay attention to the article. 'Der infektiöse Patient' (weak declension) vs. 'Ein infektiöser Patient' (mixed declension). This is where learners often make mistakes with the '-e', '-er', or '-en' endings.
Ärzte tragen Schutzkleidung, um den Kontakt mit infektiösen Substanzen zu vermeiden.
Die Proben wurden als hochgradig infektiös eingestuft.
- Comparison Forms
- The comparative is 'infektiöser' and the superlative is 'am infektiösesten'. These are used to compare the transmission rates of different diseases. 'Masern sind infektiöser als die Grippe.'
Welche Krankheit ist eigentlich am infektiösesten?
Trotz der infektiösen Natur der Krankheit besteht kein Grund zur Panik.
- News & Media
- Journalists use it to provide factual information about the spread of diseases. 'Die Gesundheitsbehörden warnen vor einer infektiösen Augenerkrankung.'
In den Nachrichten hieß es, dass der neue Erreger extrem infektiös sei.
- Medical Settings
- Doctors use it to explain risks to patients or colleagues. 'Wir müssen den Patienten isolieren, solange er infektiös ist.'
Der Arzt erklärte mir, dass die Wunde nicht mehr infektiös ist.
Achtung: Zutritt nur für Personal, das mit infektiösen Erregern vertraut ist.
- Academic & Educational
- In biology class or university lectures, you will hear about 'infektiöse Einzeller' or 'infektiöse Prozesse'.
Heute besprechen wir die infektiösen Eigenschaften von Bakterien.
Ihre gute Laune war so infektiös, dass bald alle im Raum lächelten.
- Infektiös vs. Infiziert
- 'Infektiös' describes the quality of the pathogen or the state of being able to spread it. 'Infiziert' means 'infected'—the state of having the disease. You can be infiziert without being infektiös (e.g., if the viral load is low).
Falsch: Er ist sehr infektiös mit der Grippe. (Should be: Er ist mit der Grippe infiziert.)
- Spelling Errors
- Learners often write 'infectiös' or 'infektiuous'. Remember: German likes 'k' for hard 'c' sounds in Latin roots, and the ending is always '-iös' for these types of adjectives (like 'nervös' or 'mysteriös').
Korrekt: Die Substanz ist infektiös. (Check the 'k' and the 'ö'.)
Der Patient ist nicht infektiös, aber er ist infektionsgefährdet wegen seines schwachen Immunsystems.
- Grammar: Adjective Endings
- Because it is a longer adjective, learners sometimes forget to decline it properly in complex sentences. 'Wegen des infektiösen Materials' (Genitive) requires the '-en' ending.
Man muss den Umgang mit infektiösem Material (Dative) streng regeln.
Diese Chemikalie ist giftig, aber nicht infektiös.
- Ansteckend
- The most common alternative. It is used in everyday life for colds, flu, and also metaphorically for laughter. It is less clinical than 'infektiös'.
Ist deine Erkältung noch ansteckend? (More natural than using 'infektiös' here.)
- Übertragbar
- Means 'transmissible' or 'transferable'. Often used in the context of 'übertragbare Krankheiten' (communicable diseases). It describes the possibility of the disease moving from A to B.
HIV ist eine übertragbare Infektion, aber man wird nicht durch bloßes Händeschütteln infiziert.
Die Pocken sind hochgradig kontagiös.
- Mitreißend
- A great metaphorical alternative. If you want to say someone's enthusiasm is 'infectious' but want to sound more positive and less 'medical', use 'mitreißend'.
Seine Rede war so mitreißend, dass alle sofort mitmachen wollten.
Nach der Desinfektion ist die Oberfläche praktisch keimfrei.
How Formal Is It?
Curiosidade
In the Middle Ages, 'infection' was thought to be caused by 'miasma' or bad air, long before bacteria were discovered.
Guia de pronúncia
- Pronouncing it like 'infectious' with a 'sh' sound.
- Forgetting the 'ö' sound.
- Putting the stress on the first syllable.
- Replacing the 'k' with a 'c' sound in writing.
- Missing the 'i' before the 'ö'.
Nível de dificuldade
Easy to recognize because of the English cognate 'infectious'.
Spelling with 'k' and 'ö' can be tricky for beginners.
Pronouncing the 'ö' correctly requires practice.
Clear pronunciation in formal German makes it easy to spot.
