Infections can temporarily suppress the immune system, making individuals more susceptible to secondary infections or reactivating latent viruses. Several common infections are known to have this effect. The duration and severity of immune suppression vary depending on the specific pathogen, the individual's overall health, and other factors.

Here's a breakdown of infections that can temporarily suppress immunity, based on current medical knowledge:

Influenza and Common Colds

Influenza (the flu) and common colds, caused by various viruses like rhinoviruses and coronaviruses, are well-known for causing temporary immune suppression. These infections primarily affect the upper respiratory tract and can weaken the immune system's ability to fight off other infections. The immune suppression is typically short-lived, lasting for a few days to a few weeks after the initial infection.[1] During this period, individuals may be more vulnerable to secondary bacterial infections, such as pneumonia.

Measles and Mononucleosis (Mono)

Measles is a highly contagious viral disease that can significantly suppress the immune system. The immune suppression associated with measles can last for several weeks or even months after the acute infection has resolved, increasing the risk of secondary infections.[2] Mononucleosis, often caused by the Epstein-Barr virus (EBV), also leads to immune suppression. Mono affects B cells and T cells, and the immune system can take several weeks or months to recover fully, leaving individuals susceptible to other infections during this period.[3]

COVID-19

COVID-19, caused by the SARS-CoV-2 virus, has demonstrated the ability to cause immune dysregulation. While the acute phase of the infection can lead to immune suppression, some individuals experience prolonged immune dysregulation, even after the initial infection has cleared. This can manifest as persistent symptoms, increased susceptibility to other infections, and, in some cases, autoimmune-like responses.[4] The long-term effects of COVID-19 on the immune system are still being studied, but it is clear that the virus can have a lasting impact on immune function in some individuals.

The infections that temporarily suppress immunity include Influenza, common colds, Measles, mononucleosis (mono), and COVID-19.
