Malaria Situation

Malaria is concentrated on the outer islands of Papua, Maluku, Nusa Tenggara, Sulawesi, Kalimantan and Sumatra. It occurs with low frequency or is absent on the islands of Java and Bali where approximately 70% of the population live. All species of human malaria parasites are found in Indonesia.  Recently, country reported about existence of P. kowlesispecies also.  Formerly, P. malariae and P. ovale were mostly found in the eastern part of Indonesia, Nusa Tenggara Timur and Papua. Around 117 million people are at varied degrees of risk. Malaria transmission in Indonesia is perennial.  P. vivax and P. falciparum are the most common types of malaria species prevalent in the country.

During pre eradication era, the malaria situation in Indonesia was as bad, if not worse, as in India.  The estimated malaria cases and deaths were around 30 million (in Java and Bali only) and 0.12 million  respectively annually.  But due to result of progress in eradication programme, the island of Java and Bali was practically malaria free by 1964.  From 1965, the situation began to deteriorate the malaria incidence gradually increased and disease spread over the islands.  In 1968, the malaria eradication services extended to areas of social-economic areas in other islands.

Since the last five years, nearly 350 000 confirmed cases and 1.25 million – 2.50 million probable malaria cases, with 45%–50% of them being cases of P. falciparum, and around 500 confirmed malaria deaths are reported every year. The average annual blood slide examination rate (ABER) was <2 at the national level but the rate is improving in selected areas with increased support from the Global Fund.

Most of the control programme has been carried out in Java-Bali.  The residual foci are in Central Java.  Drug resistance to P.falciparum is a problem and has been identified in all the provinces.  Low to moderate level of resistance also noticed for SP compound as well as Mefloquine in Irian Jaya.  P.vivax resistance to chroroquine was first reported in 1991 from Irian Jaya province.  At present, country has adopted ACT for treatment of both types of malaria species.

Vectors: An. maculatus, An.sundaicus, An. aconitus, An.barbirostris, An.subpictus and An.koliensis and An. farauti

*      Malaria is a greater problem in outer islands

*      Recipient of GFTAM support for malaria control in 16 provinces since Rd 1. UNICEF support is also available for limited activities.

Use of ITNs/LLINs is the main vector control measure. During 2008-2010 a total of 4.41 million LLINs were distributed (Fig. 2). The IRS activity in the country is very limited and is applied only for outbreak management and occasionally for reducing malaria transmission in highly endemic areas. ACTs and RDT are being used since 2005. During 2010, 671 681 ACT courses were distributed (Fig. 3).

The malaria situation is worsening since the last few years. The malaria surveillance system is weak and needs to be strengthened. However, the country is planning to eradicate malaria from Java-Bali, Bintan and Batam. Indonesia is a large and geographically complex nation. The annual need for resources is around US$ 24 billions but there is a huge gap between availability and need. The National Malaria Control Programme (NMCP) is receiving assistance from GFATM and Unicef (Fig 4).    During 2010, country received around 19.77 million. The expenditure pattern of the country is depicted in Fig. 5.  The detailed data for 2010 is not available.

Goals and Targets:

 

To reduce malaria morbidity and mortality until the disease is no longer a public health problem in the country.

 

 Targets

Baseline data in 2005

2010

To reduce the morbidity by 50%of the rate in 2000 by the year  2010

4.02 / 1000

2.01/ 1000

To reduce the mortality by 75%of the rate in 2000 by the year 2010

0.54/ 100000

0.14 / 100000

All suspected malaria cases should be tested and all confirmed cases treated with efficacious treatment

46.5%

90%

All malaria outbreaks should be detected and reported

100%

100%

Malaria elimination in Jakarta, Bali and Batam

 

Prepare strategy and implement for elimination

 

Control strategy: 

*     Passive Case Detection , clinical diagnosis and treatment and   Active Case Detection, laboratory diagnosis is limited in Java-Bali area.   Treatment in the periphery through health centres and malaria treatment post by volunteers.

*     Vector control: selective IRS, bednets, larviciding, biological control and source reduction.

*     DDT has been replaced by synthetic pyrethroid, carbamate and OP, permethrin is used for bednet impregnation.

 

Achievements and Initiatives

*      New Drug Policy has been implemented since 2003

*      Outbreaks prevention and early containment in disaster area (earthquakes, floods, outbreaks, etc)

*      New strategic plan 2009 – 20014

*      Expansion of partnership: donors, medical professions, private, etc

Issues and Challenges:

*      Drug resistant P. falciparum malaria is spreading.

*      Lack of resources, and trained professional staff.

*      Monitoring and evaluation of activities under taken at provincial and district level.

*      Microscopic services and finances required for implementing changes in anti-malaria drug policy are very costly; and since alternative drugs have not been available, improving therapeutic efficacy of the existing anti malarial drugs will be a challenge.

*      Emergence of mono and multi-drug resistance in P falciparum and chloroquine resistance in  P. vivax may have contributed to this rise in malaria.

*      Chloroquine resistance in P vivax is a serious problem in Irian Jaya (Papua) Province. The programme has evaluated mefloquine and artesunate monotherapy and these drugs have produced good therapeutic efficacy.

*      The main reason for the deteriorating malaria situation were the economic crisis that commenced during 1996-97 has adversely affected malaria control programme, particularly vector control activities. In the absence of vector control, epidemics have occurred in some parts of the country.

*      The lack of intersectoral action and negligible community participation has contributed to the failure in vector control.

*      Increasing population mobility has caused malaria and often drug resistant strains to spread to various parts of the country.

*      Inadequate self-treatment, poor compliance of three-day chloroquine treatment; inadequate monitoring of drug resistance; drug failure,  decentralization of malaria control programme, relaxation of malaria surveillance system and lack of quality drugs may have all contributed to and compounded the problem of malaria control.
