About Lyme Disease

  • It is a vector-borne infectious disease caused by the bacterium Borrelia burgdorferi.
  • Transmission:

It is primarily transmitted to humansthroughthe bite of infected black-legged ticks, often referred to as deer ticks.

Lyme disease cannot spread:

  • between humans
  • from pets to humans
  • through air, food, or water
  • Lice, mosquitoes, fleas, and flies also do not transmit it.
  • It is most commonly reported in North America, Europe, and some parts of Asia.
  • Symptoms:
  • Early symptoms of Lyme disease start between 3 to 30 days after an infected tick bites you. The symptoms can include:
  • A red rash called erythema migrans (EM). Most people with Lyme disease get this rash. Itgets bigger over several days and may feel warm. It is usuallynot painful or itchy. As it starts to get better, parts of it may fade. Sometimes this makes the rash look like a "bull's-eye."
  • Fever
  • Chills
  • Headache
  • Fatigue
  • Muscle and joint aches
  • Swollen lymph nodes
  • If left untreated, it can lead to more severe symptoms, affecting the joints, heart, and nervous system.
  • Treatment:
  • The standard treatment for Lyme disease isantibiotics, such as doxycycline or amoxicillin, especially in the early stages.
  • In later stages, intravenous antibiotics may be required. 

Q1: What is a Vaccine?

Vaccination is a simple, safe, and effective way of protecting you against harmful diseases, before you come into contact with them. It uses your body’s natural defenses to build resistance to specific infections and makes your immune system stronger. Vaccines train your immune system to create antibodies, just as it does when it’s exposed to a disease.
