  1. Current Malaria Situation-Bangladesh

  2. MALARIA FACTS Country Area 147,570 sq. km and Pop. 143.8 million 13 out of 64 districts are high endemic 13.3 million people are at high risk 60,000 - 75,000 lab confirmed cases per year Estimated 1.0 million clinical cases annually Focal outbreaks in eastern border are not infrequent High level of Drug resistance (CQ,SP) against pf malaria reported in CHT and other endemic district.

  3. Malaria cases and deaths

  4. Malaria Outbreaks 1989-2003 Sylhet: '91(2), '92(1), 93(1), '95(1), 98 (1) Sunamganj: '90(1), '91(1), '92(1), '93(1), '95(1), 98 (1), 2000 (1), 2003(1) MBazar: '89(2), '90(1) Habiganj: '91(1), '92(1) Kurigram: '92(1), Netrakona: '91(1), '92(2), '93(2), '94(2), '95(1) 2000 (1), 2002(1) Sherpur: '89(2), '92(1), '95(1) Mymensingh: '92(1), '94(1), '95(1)

  5. Background of Malaria Control Program • Malaria eradication program (MEP) started in 1961 and continued until 1976 • In 1977 the MEP merged with PHC and Control program was launched. • In 1994 Revised malaria Control Strategy was adopted • In 1998 piloting of Roll Back Malaria started in one of the Hill Tract District

  6. Objective of the Program • To reduce malaria specific mortality rate by 50% by the year 2010 • To provide early diagnosis and prompt treatment (EDPT) to all malaria cases • To plan and implement selective and sustainable vector control measures including use of Insecticide Treated Mosquito Nets (ITMN) and Indoor Residual Spraying (IRS)

  7. Objective of the Program (Cont’d) • To develop and strengthen the malaria epidemiological surveillance system in order to provide adequate information for the planning and resource allocation required for malaria control activities at various levels

  8. Program Priorities and Strategies • The adoption of the three malaria clinical case definitions of Uncomplicated Malaria Confirmed (UMC), Uncomplicated Malaria Presumptive (UMP), Severe Malaria (SM) for the Early Diagnosis and Prompt Treatment (EDPT)

  9. Program Priorities and Strategies (Cont.) • The adoption of revised reporting forms for Malaria Epidemiological Surveillance, which allow for the reporting of malarial deaths • Establishment of a community based Insecticide Treated Mosquito Net (ITMN) program

  10. Program Priorities and Strategies (Cont’d) • Strengthening of the epidemic preparedness and response capacity at the national, district and upazila levels.

  11. Epidemiological Types of Malaria Five major epidemiological types based on ecology and vector distribution as follows: • Malaria of Forested hill • Malaria of Forest Fringe • Malaria of plain Border Belt areas • Malaria of plain rural areas • Malaria in plain urban areas

  12. Entomological Information • Out of 34 Anopheles species (Spp.) recorded in Bangladesh, 7 (seven) Spp. have been incriminated as malaria vector • These are: An.dirus, An.minimus, An.philipinensis, An. sundaicus, An.aconitus, An.anularis and An.vagus. • An.maculatus group is strongly suspected to be a new vector in certain areas of northern border districts.

  13. Vector Control Activities • DDT has been used over 30 years as the only insecticide for residual indoor spraying until 1991 • Since 1994, two insecticides; Malathion 57% EC for IRS and Deltamethrin 2.5% EC and 1% SC for treatment of bed-nets have been used for malaria vector control in the country

  14. Vector Control Activities (Cont’d) • A total of about 120,000 to 140,000 mosquito nets are being treated each year. • The program is planning to introduce LLNs with the support from WHO

  15. Drug Policy and Drug Regimen • Due to high level of resistance against CQ and SP the malaria treatment regimen has been changed • UMC: When diagnosis is confirmed by Blood slide examination or RDT. The treatment is Coartem (ACT) for falciparum malaria.

  16. Drug Policy and Drug Regimen (Cont’d) • UMP: When presumptive diagnosis is done without laboratory confirmation by blood slide examination or RDT. The treatment for this category of patient is CQ + PQ • SM: Parenteral quinine until the patient is able to take orally followed by oral quinine with a total duration of 7 days

  17. Epidemic preparedness • Epidemic outbreaks are not infrequent • Rapid Response Team (RRT) formed at district level • Civil Surgeon (District Health Officer) is the Team Leader of RRT • A guideline has been developed • Team members of RRT has been oriented based on the guidelines • Buffer stocks of logistics to combat epidemics is maintained • Health personnel working in the epidemic prone areas alerted
