Did You Know?
Some infections can indirectly affect your body in other ways. For example, serious infections or medications can sometimes lead to temporary side effects like reduced stamina or energy. In some men, this may affect sexual performance. A product like Fildena 100 is sometimes used to treat erectile dysfunction, but it should only be taken under a doctor’s advice.
Conclusion
Infectious diseases can be dangerous, but they are often preventable and treatable with the right steps. Knowing the symptoms and causes helps you act fast. Always follow hygiene rules and see a doctor if you feel sick for more than a few days.
