STATE VECTOR BORNE DISEASE CONTROL PROGRAMME
. The control programme for Malaria began in Mizoram in the year 2005 whereas Dengue Control Programme was initiated during 2012-2013. Although much has been accomplished already during the last ten years, there is so much work that lie ahead if we are to eradicate Malaria altogether. Among the six vector borne diseases Malaria still remains a major public health problem in the State. Dengue is also on the rise although the cases are few and no fatality had been reported. Beside indigenous Malaria and Dengue, Japanese Encephalitis posses a potential threat to the State. As Culex Mosquitoes are prevalent in the state, there is also every possibility of Acute Encephalitis Syndrome / Japanese Encephalitis (JE) occurrence in the State as suspected cases have been reported. Other vector borne diseases such as Chikungunya, Kala-azar and Lymphatic filariasis have not been found in the State as of now.
Although the indigenous malaria disease incidence and death rate were on decline during the last 3 or 4 years, the year of 2014 – 2015 saw a steep rise in positive cases and a slight increase in mortality. This was partly attributed to scanty intermittent rainfall with warm and humid climate reported throughout the State and increased surveillance. Positive cases increased throughout the State from low endemic to high endemic Districts. There were also reports of focal outbreaks from few high endemic Districts. However, the situation was put under control and deaths were prevented as far as possible with the combined efforts of the District and the State with continued support and guidance from the Directorate of NVBDCP, New Delhi.
In this regard, the SVBDCP, Mizoram is very grateful to the Central Government for assisting the State financially and materially in the control of vector borne diseases especially Malaria and It would continue to work its best in combating the dreadful diseases and reduce the burden on health and economic development of the thousands affected by these vector borne diseases.
The Salient points or current status on Malaria and Dengue in Mizoram are as follows:
STRATEGIC PLAN FOR MALARIA CONTROL IN INDIA (2012-2017)
To reduce the morbidity and mortality due to malaria and improving the quality of life, thereby contributing to health and alleviation of poverty in the country.
To achieve by the end of 2017, an API of < 1 per 1000 Population at National Level.

MIZORAM STATE GOALS AND TARGETS FOR THE 12TH FIVE YEAR PLAN :
|Year||STATE GOALS FOR THE 12TH FIVE YEAR PLAN|
|2012-2013||>16.5%||< 5||< 22|
|2013-2014||>18%||< 4||< 16|
|2014-2015||>19.5%||< 3||< 11|
|2015-2016||>21%||< 2||< 8|
|2016-2017||>22.5%||< 1||< 5|
Considering the high incidence of Malaria in Mizoram, especially with Malaria Pf rate of over 95.09 %, the SVBDCP, Mizoram, is of the opinion that blanket coverage of DDT spray, distribution of LLINs, Impregnation of bed nets, Entomological surveillance and environmental management in the whole state is pertinent. Example can be cited for the same on how 4 years back DDT spray was not undertaken in few areas where API was less than 2. Consequently, it was found out that Malaria incidence increased to a great extent in the following years in those unsprayed areas. Apart from DDT spray and LLIN, it is felt that much of the Malaria cases and the few fatalities which were witnessed during 2014 could have been prevented with impregnation of local bed nets as it is most acceptable to the community. However, due to non supply of K-Othrine (Deltamethrin 2.5%) for impregnation of bed nets, it was witnessed that the API still remains very high in spite of improved IRS coverage in many endemic regions. Apart from these, vector control through Entomological surveillance and Sanitation drive are of the utmost importance for which the implementation have not been done. Hence, provision for impregnation of bed nets, setting up of Entomology cell and environmental management are crucial to the State and are regarded to be the major factors in preventing deaths due to Malaria. Provision for impregnation of bed nets is essential as majority of the population prefers to use their own bed nets which have their tailoring of choice over distributed LLINs.
After careful analysis of the State situation and performance, the yearly API target set during the 12th Five year plan was found not feasible and farfetched. All the while keeping the State Goals in mind, yearly revised targets set are as below:
OBJECTIVES AND TARGETS OF DENGUE CONTROL PROGRAMME:
OBJECTIVES : Following are the specific objectives of the Mid Term Plan
By the latter part of 2012, Dengue and Chikungunya Control Programme was implemented in the State. Civil Hospital, Aizawl was identified as Sentinel Surveillance Hospital for Dengue. Random Sampling was done from the OPD patients and 6 cases were found to be positive for Dengue infection in the year 2012, 7 cases in the year 2013 and 19 cases in 2014.
Due to delayed release of funds in 2012 (as well as unreleased of funds) for Dengue and Malaria in the second instalment, the State faced problems in procurement of Dengue NS1 antigen test kit. The IgM MAC ELISA test kit (96 test) received from NIV Pune was used up within a short period of time and the State could not proceed further in diagnosing Dengue Disease during 2012-2013. Then in 2013 – 2014, the same amount of test kit (i.e 96 test kits) was received and the State had to procure additional test kits from the SSH budget, 246 suspected cases were tested and out of which 19 were found to be positive for Dengue.
It was also felt necessary to increase the number of Sentinel Surveillance sites to have better coverage of the population at risk. Keeping in mind the high percentage of patient attendance in Private Hospitals of the State, setting up additional Sentinel Surveillance sites at three other hospitals, namely, Presbyterian Hospital, Durtlang in northern Mizoram, Civil Hospital, Lunglei and Christian Hospital, Serkawn in the southern part of Mizoram was proposed.
The proposed additional Sentinel Surveillance Site for Dengue was approved and will be setup at Civil Hospital, Lunglei. ELISA reader and washer will be procured and installed as soon as the funds are released.
STATUS OF MIZORAM FOR DENGUE IS AS FOLLOWS:
|Year||Suspected Cases||Positive Cases||Deaths|
Note – 5 cases were detected in the year 2010 from Private Hospital before programme was implemented in the State.
The disease situation in Mizoram State is as below:
|Year||Malaria Cases||Malaria Deaths||Dengue Cases||Dengue Deaths||Chikungunya Cases||
|Kala-azar Cases||Kala-azar Deaths||Micro-filaria Rate %|
In the State, Malaria is still a major public health problem till date. 32 cases of Dengue have been identified from 2012-2014. Two cases of registered death due to suspected AES/JE were also seen in the state but due to lack of diagnostic facilities, the cases were not confirmed and the actual prevalence of the disease cannot be estimated as yet.
Malaria is endemic (API>2) in 5 districts (out of 9) namely :
