Visa issuance and TB infection (inactive or active) 

All the above countries will not issue you an entry Visa if you have inactive or active TB infection or Disease. 

Your TB Chest X Ray must be absolutely Normal without any scars or any features of abnormalities. 

Some abnormal Chest X Rays are not necessarily that of TB infection or Disease however due to the high restrictions levels, all abnormalities will be taken as TB infection or disease especially from persons coming from high TB prevalence countries like Uganda, India, Pakistan, Yemen, Kenya, Sudan etc. 

Before you start processing for your GCC Visa, it will be worthwhile for you to undergo a medical examination from a trusted health care center and a trusted Radiologist report. 

Kalson Medical Services can offer you this service prior your final medical examinations as well as offer you an in-depth consultation and advise if you should proceed with your visa application or not.


Not everyone infected with TB bacteria becomes sick. As a result, 2 TB-related conditions exist: latent (inactive) TB infection and TB disease.

Latent (inactive) TB Infection

TB bacteria can live in the body without making you sick. This is called latent or inactive TB infection. In most people who breathe in TB bacteria and become infected, the body is able to fight the bacteria to stop them from growing.

People with latent TB infection:

  • Have no symptoms
  • Don’t feel sick
  • Can’t spread TB bacteria to others
  • Usually have a positive TB skin test reaction or positive TB blood test
  • May have an abnormal Chest X Ray with a scar.
  • May develop TB disease if their immunity drops down

Many people who have latent TB infection never develop TB disease. In these people, the TB bacteria remain inactive for a lifetime without causing disease. But in other people, especially people who have a weak immune system, the bacteria become active, multiply, and cause TB disease.

TB Disease

TB bacteria become active if the immune system drops down. When TB bacteria are active (multiplying in your body), this is called TB disease.

People with TB disease are sick. They may also be able to spread the bacteria to people they spend time with every day.

Many people who have latent TB infection never develop TB disease. Some people develop TB disease soon after becoming infected (within weeks) before their immune system can fight the TB bacteria. Other people may get sick years later when their immune system becomes weak for another reason.

For people whose immune systems are weak, especially those with HIV infection, poor nutrition, diabetes or other chronic illnesses the risk of developing TB disease is much higher than for people with normal immune systems.

The Difference between Latent TB Infection (LTBI) and TB Disease

The Difference between Latent (inactive) TB Infection (LTBI) and TB Disease

A Person with Latent(inactive)

TB Infection

A Person with TB Disease

·         Has no symptoms

·Has symptoms that may include

o    a bad cough that lasts 3 weeks or longer

o    pain in the chest

o    coughing up blood or sputum

o    weakness or fatigue

o    weight loss

o    no appetite

o    chills

o    fever

o    sweating at night

· Does not feel sick

· Usually feels sick

· Cannot spread TB bacteria to others

· May spread TB bacteria to others

·Usually has a skin test or blood test result indicating TB infection

· Usually has a skin test or blood test result indicating TB infection

· Has a normal chest x-ray and a negative sputum smear

· May have an abnormal chest x-ray, or positive sputum smear or culture

· Needs treatment for latent TB infection to prevent TB disease

·  Needs treatment to treat TB disease

During your Medical examination that includes a TB Chest X Ray, if the Medical Doctor finds that your Chest X Ray is abnormal and that the abnormality is consistent with TB infection, it may be that you have been exposed to TB Bacteria previously hence inactive TB or you were treated for TB Disease.


Preventing Latent TB Infection from Progressing to TB Disease

Many people who have latent TB infection never develop TB disease. But some people who have latent TB infection are more likely to develop TB disease than others.

Those at high risk for developing TB disease include:

  • People with HIV infection
  • Physiological stress including Mental stress
  • Poor or inadequate Nutrition
  • Alcoholism
  • Asthmatic persons using steriods
  • People who became infected with TB bacteria in the last 2 years
  • Babies and young children
  • People who inject illegal drugs
  • People who are sick with other diseases that weaken the immune system
  • Elderly people
  • People who were not treated correctly for TB in the past

Preventing Exposure to TB Disease While Traveling Abroad

In many countries, TB is much more common. You should avoid close contact or prolonged time with known TB patients in crowded, enclosed environments (for example, clinics, hospitals, prisons, or homeless shelters, etc).

Air travel itself carries a relatively low risk of infection with TB of any kind.

 If you will be working in clinics, hospitals, or other health care settings including caring for the elderly persons where TB patients are likely to be encountered you should consult with your employee about the risks.

You should request for personal protection devices critically N95 nasal masks for protection.

If you anticipate possible prolonged exposure to people with TB (for example, those who expect to come in contact routinely with clinic, hospital, prison, or homeless shelter populations) you should have a TB skin test, a TB Chest X Ray.

 If the test reaction is negative, you should have a repeat test 8 to 10 weeks after the exposure has ended.

Additionally, annual testing may be recommended for those who anticipate repeated or prolonged exposure or an extended stay over a period of years.
