The diseases and its effects

Fever, the common cold, TB, HIV/AIDS, and COVID-19 are all illnesses with different symptoms. The respiratory system is impacted by COVID-19, which can have serious health consequences. HIV/AIDS weakens immunity, making a person more vulnerable to infections and malignancies. Lung-related tuberculosis (TB) can be lethal if left untreated. Sneezing, coughing, and runny nose are typical cold symptoms. Hygiene and vaccinations are examples of preventive actions that are vital.
