Traiter vs. soigner

The French words 'traiter' and 'soigner' both relate to the concept of addressing a health issue, but they are used in different contexts and with slightly differing connotations.

Traiter

'Traiter' generally refers to the process of treating a condition or disease, which can involve medication, therapy, or a broader range of medical interventions.
Le médecin traitera votre infection avec des antibiotiques.
(The doctor will treat your infection with antibiotics.)
Cette clinique traite les patients souffrant de maladies chroniques.
(This clinic treats patients suffering from chronic diseases.)
Pour traiter la dépression, il peut être nécessaire de combiner thérapie et médication.
(To treat depression, it may be necessary to combine therapy and medication.)

Soigner

'Soigner' implies providing care or attention to someone's health, often suggesting a more personal or direct level of care. It can also mean to nurse someone back to health.
Elle soigne son grand-père atteint de la grippe.
(She is taking care of her grandfather who has the flu.)
Les infirmières soignent les blessures avec beaucoup d'attention.
(The nurses tend to the wounds with great care.)
Il faut bien soigner cette entorse pour éviter les complications.
(This sprain must be well cared for to avoid complications.)

Summary

'Traiter' often encompasses a wider scope of medical treatment involving various methods, whereas 'soigner' has a more nurturing connotation associated with personal care and attention to someone's health. Though both words engage with the act of helping someone get better, 'traiter' is more clinical and broad, while 'soigner' is typically more hands-on and individualized.
