Introduction
The Government of sultanate of Oman since the
early years of the renaissance give the health
status and food safety of the country its most
important priorities.
So they established hospitals, health centers and
veterinary clinics and quarantines.
And sets the degrees and laws governing these
facilities.

Epidemiology
THE REGIONAL SEMINARFOR OIE NATIONAL FOCALPOINTS ON ANIMAL PRODUCTION FOOD SAFETY
JAN 2014
Control of TB in Human
National Tuberculosis Program (NTP) in Oman was
initiated in 1981. Since then there is decrease in TB
cases (all forms) from 928 in 1981 to 213 in 2010.
The rate of sputum positive TB cases decreased from
21/100,000 in 1981 to 4.29/100,000 in 2010

TB
Control Program
1.
Structure:
 The program manager sits in the Ministry of
Health.
 He operates with assistance of Regional TB
Focal Points who are assisted by TB focal
points in each primary health care center.
 The regional epidemiologist monitors the
disease activity at regional level.

2. Activities & Achievements
 The TBCP is implemented through a system of monthly reporting of
disease diagnosis, treatment, contact screening and Latent TB
treatment.
 The program established and expanded as follows:

(1996),
MDR surveillance (1998),
INH Preventive Therapy in children < 6 years (1998),
Treatment of LTBI in close contacts (2006), Fixed Drug
Combination,

3. FUTURE:
 Electronic Nominal Registration System (ENRS) is
introduced by WHO for the recording and reporting of all
National TB activities. Oman aims to progressively introduce
this system in all its regions over the next 5 years.
 The private health sector is rapidly expanding in Oman.
This sector caters for non-nationals working in private
business sector but also for Omanis. It is the aim of the
National TB Control Program to full involve this sector in
the National TB Control Program activities.
 In order to decrease the rate of transmission of TB to
minimum, molecular epidemiology will be undertaken to
fully understand the pattern of transmission of TB in the
country.
 In order to rapidly diagnose TB and resistance, it is under
consideration to introduce molecular diagnostic techniques ).

Control of TB in Animals
 Surveillance of TB in animal herds:
•
Zoonotic disease comity managed by DG of animal wealth
department (Ministry of agriculture &fisheries):
1. operates with assistance of regional endemic disease
focal points who are assisted by veterinary doctors in the
regional veterinary clinics which monitoring the farms
and monthly reporting of disease diagnosis by regularly
sending samples to the Central Veterinary Research
Laboratory( CVRL), treatment, contact screening and
Latent TB treatment
2. In 2013, the Central Veterinary Research Laboratory
( CVRL) received 200 samples submitted for
mycobacterium spp., and results was found negative.

• Regional central slaughter houses (Ministry of
Regional Municipalities &Water Resources:
1. Veterinary doctors and specialists monitoring the
disease through post mortem examination of the
slaughtered carcasses.
2. No. of animal slaughtered in 2013:Slaughters surveillance

• Veterinary quarantine at the all borders (Ministry
of agriculture and fisheries) :
1. Veterinary doctors and specialists at the borders
monitoring the disease by:
- Applying the requirements of importation .
- Inspect imported live animals and all animal
products and by products.
- continuously sending samples to:
Central Veterinary Research Laboratory(CVRL)
Central Health Laboratory (CHL)

 Prevention Precautions:
•
•
•
•
•
Veterinary quarantine department sets specific requirements
compatible with the recommendations of the OIE for
importation of bovine spp for breading or immediate
slaughtering purpose , and bovine products (meat – milk ),
bovine embryos/ semen.
Restrictions of animal movements between different regions
according to regulations of ministerial law 12/2005.
Continuous laboratory diagnosis of submitted suspected
samples.
Hygienic disposal of infected organs and carcasses.
Increase population awareness programs.

CHALLENGES
• Oman one of the consuming countries , import
90% of its food which make a challenge for the
food safety authorities.
• Insufficient population awareness of TB disease.
• Insufficient of veterinary diagnostic service
capability comparatively with the increasing of
animal population.

Future
1) Trying to strengthen import restrictions to control movement of animals and
animal products from countries in which Bovine Tuberculosis is known to
exist.
2) Improvement of animal health infrastructure required for controlling and
preventing Bovine Tuberculosis.
3) Increasing veterinarians and related technical support staff to implement
adequate surveillance and control of the disease.
4) Increasing laboratory capability to diagnose Bovine Tuberculosis.
5) Trying to apply a surveillance to detect Bovine Tuberculosis through slaughter
monitoring and/or tuberculin testing if it were present and identification the
epidemiological situation.
6) Apply animal identification system to trace the herd of origin of any reactor to
a tuberculin test to recognized additional at-risk animals and/or herds and
testing them.
7) Increasing awareness about food safety and Bovine Tuberculosis with
encouraging farmers to cooperate by presenting their animals for testing.
8) Trying to intensify the legal authority.
