  • 2. Goal of Anti Malaria MonthAnti –Malaria month is being observed all over India in the month of June.June, being the pre Monsoon month has been selected for creatingawareness among the masses against Malaria, a fever caused by a parasitetransmitted ensure appropriate public health focus to improved access toprimary health care, preby mosquito bite. The AMM campaign is also anattempt to enlarge and vention and control of communicable diseasesIncluding vector borne diseases, reduction of infant mortality rate andmaternal mortality ratio by 50% by year 2012 and promotion of healthylife styles as per the goals of the National Rural Health Mission launchedby the GoI in April 2005.
  • 3. Objective of Anti malaria MonthThe specific objectives of the Anti Malaria Month campaign strategy through BCCare as under:1.Enhance awareness regarding source and transmission riskreduction, treatment, availability of services at different levels2.Promote attitudinal and value changes among target audiences leading toinformed decisions, modified behaviour, desirable practices at individual andsocietal level3.Stimulate increased and sustained demand for quality prevention and careservices and optimal utilization of available health care services4.Build support for the programme across inter-sectoral partnerorganizations, influential sectors of society (corporate houses, politicalrepresentatives, social activists, media, civil society organizations, etc.) and healthcare service providers and elicit commitment for action5.Ensure availability of services.

  • 16. e. Epidemic preparedness and response:Under NVBDCP, it is visualized that everydistrict in the country should have rapidresponse teams for undertaking promptremedial measures in the event of an outbreakof malaria.
  • 17. f. Monitoring and Evaluation of theProgramMonthly Computerized Management InformationSystem(CMIS)Field visits by Program Officers / personnelField visits by Malaria Research Centers andother ICMR InstitutesFeedback to states on field observations forcorrection actions.
  • 18. Logistic and Anti Malarial DrugManagementThe norms for calculation of Anti-malarial drugs to avoid stock-outs even inthe circumstances like unforeseen outbreaks and procurement delays are asfollows:•The data of positive malaria cases of the last completed year is taken asbasis for calculation.•25% additional quantity is to be taken as buffer on the technicalrequirement.•In declining trend of malaria cases, the chance of outbreak is always there.Therefore the maximum possible deviation may be up to maximum number ofcases reported in any of the years during the decade may be considered.This figure should also be considered for calculation of requirements ofanti-malarias. This factor is also considered especially when underreporting is known.
  • 19.  Objectives- to prevent deaths due to malaria- to reduce malaria morbidity- to maintain agriculture and Industrial- production through intensive anti malariameasures in such areas-to consolidate the gains achieved so far Areas were reclassified based on the Annual Parasitic Incidence(API) as those having API > 2 and those having < than 2 foroperational purposes
  • 20.  Regular 2 rounds of insecticidal spray withDDT/ Malathion / Synthetic Pyrethroids at thedose of 1, 2, 0.5 mg/sq meter respectively. Entomological assessment for vector behaviorand development of insecticidal resistance Active and passive surveillance is carried outonregular basis every fortnight Presumptive Treatment to all fever cases andradical treatment to all slide positive cases isgiven
  • 21.  Regular spray is not carried out but ‘focal’spray is carried out around falciparum casesdetected during surveillance Regular passive surveillance once in a fortnight Treatment –All positive cases to receive radicaltreatment Follow up- All positive cases to be followed upfor 1 year at monthly intervals aftercompletion of radical treatment Epidemiological investigation of all malariapositive cases .This may also include mass bloodsurvey.
  • 22.  Investigation of all Malaria Deaths-All cases suspected to have died due to malaria are tobe investigated Monitoring and control of allepidemics and focal out breaks ofmalaria –Any increase in the number of fever cases suggestiveof malaria should be promptly investigated andmeasures to contain the outbreak should beinstituted.
  • 23. Definition:Anti-larval operations causing the reduction orpermanent elimination of mosquito breeding places orsites are defined as source reduction methods. Sourcereduction primarily aims to prevent development ofaquatic stages of mosquito larvae reducing breedingsource. These methods are environment friendly,economical in the long run with minimum maintenance andsurveillance.Guidelines on Source Reduction
  • 24. Source reduction methods are furtherclassified into1. Elimination or reduction of breeding sites primarilyinvolving engineering methods.2. Environmental manipulation.
  • 25. Advisory for Control -Vectors ofmalaria, dengue and chikungunya1. Source Reduction.Elimination of breeding sites by removing potential breeding places like waterbottles, solid waste, coconut shells, tyres, etc.Weekly cleaning/Drying of watercontainers, Room coolers. Extensive IEC activities for social mobilization of thecommunity on preventive measures and destroying breeding habitats.Minor Engineering measures like proper placing of lids of overheadtanks, underground tanks, repairing of leakage from pipeline and preventions ofover flowing tanks, channelizing of water collections in roof and cleaning ofgutters/water outle ts.Overall general sanitation in and around domestic environment.2. Anti larval Measures:Application of weekly anti- larval (Temephos, Bti. etc.) in water collections in andaround domestic environments.Release of larvivorous fish in permanent water bodies, ornamental tanks etc.3. Adult Control Measures:Indoor Space spray with DDT.Outdoor fogging with malathion
  • 26. GUIDELINES FOR ITBNS AND LLINSPreface:Malaria transmitted by the bite of mosquitoes and the protozoacompletes life cycle. Pregnant women, babies and young childrenare at the greatest risk of dying of malaria. Sleeping under a bednet reduces the risk of man-vector contact as mosquitoes bite atnight and is thus an effective preventive measure. But ordinarymosquito nets provide limited physical barrier between mosquitoand man and protection as they may still bite through the net orget inside the net following improper use. The Insecticide TreatedBed nets (ITBNs) or Long Lasting Impregnated Bed nets (LLINs)provide better and effective protection by keeping awaymosquitoes as well as killing them. ITNs and LLINs also kills orkeeps away other nuisance insects . cockroaches, bedbugs,houseflies, fleas, etc.
  • 27. INSECTICIDE TREATED BED NETS(ITBNS)Insecticide treatment is recommended for synthetic nets(nylon, polyester), as treatment of cotton nets is not cost-effective and effect of insecticide is not long lasting.Insecticides used for mosquito nets are not harmful topeople, if used correctly. Direct skin contact with theinsecticide on a still wet net may cause a tingling sensationon the skin. This is not harmful, even for small children.After treatment, the net may smell of insecticide. This willgo away in a few days and is not harmful to people who sleepunder the net.
  • 28. LONG LASTING INSECTICIDAL NETS(LLINS)LLINs are mosquito nets which have the insecticide incorporated intheir fibre, so that it is not removed by as many as 20 washes.Because these nets have an even and quality controlled insecticideapplication, they are generally more effective than conventionalITNs. Furthermore the LLIN is more cost-effective (as it can be usedfor 3-5 years) than distribution of conventional bed nets andtreating them with insecticide once or twice a year. ConventionalITNs are therefore only a rational option in areas, where thepopulation already has so many nets that at least 50% of peoplesleep under one.
  • 29. For a given village the number of LLINs to be provided isusually equal to the number of households multiplied by 2 orthe total population divided by 2.5. However, some villagesmay have many large households, which will need additionalnets. It is therefore prudent to add 20%, i.e. plan:►Number of LLINs = Number of households x 2.4.This will normally ensure a sufficient quantity for thefollowing schedule:1-2 persons: 1 LLIN3-5 persons: 2 LLINs6-7 persons: 3 LLINs8-10 persons: 4 LLINsDISTRIBUTION OF LLINS
  • 30. Generally, for a targeted village, the required number of LLINs should bedistributed in one single operation.However, if LLINs are not in sufficient supply, it can be considered todistribute one per household per year over a period of two years, i.e. withtwo rounds of distribution separated by 12 months.Timing of LLIN distribution is less critical than the timing of IRS or re-treatment of nets. However, for educational as well as logistical reasons,distribution shortly before the start of the rainy season may be optimal.In addition to distribution to targeted high-risk villages aiming at completepopulation coverage, LLINs should be given to pregnant women in high riskareas and to special groups such as children in tribal schools and hostels.These children should take the nets home with them during vacations.
  • 31. Insecticides Used in Vector Control
  • 32. It is essential that residual insecticidal spray should be planned andimplemented with sound technical skill under expert guidance.It should not be entrusted to non-technical personnel like contractors,voluntary bodies etc.In the revised approach to malaria control, it has been decided to sprayhumandwellings and mixed dwellings.Cattle sheds are not to be sprayed with a view to conserve insecticide,improve coverage of human dwellings and the present diversion ofmosquitoes from sprayed cattle sheds to human dwellings.Insecticide spray operations:
  • 33. Planning for spray operations:Spray operations are to be carried out in all area withAPI 2 or above. However, the priority of spray will begiven to High Risk areas all over the country.S.No. Name of highrisk PHCPopulationof PHCNo. of highrisk sub-centres inPHCHigh riskpopulationfor sprayRemarksPHC and sub-centres of “High risk” areas for spray operations

  • 35. The spray lance should be kept 45 cms (18 inches) away fromthe wall surface.The swath should be parallel.Spray is applied in vertical swath of 53 cm (21 inches) wide.Successive swaths should overlap by 7.5 cm (3 inches).Spray is done from roof to floor, using downward motion, tocomplete one swath; then stepping sideways and sprayingupwards from floor to roof.Do not let the spray drip to the floor.Spraying is done on inner surfaces including eaves and roofs.Important points to be remembered duringIRS
  • 36. The discharge rate should be 740 to 850 ml per minute.To obtain the above discharge rate, the pump man shouldgive 20 to 26 strokes per minute with 10-15 cms plungermovement at a pressure of 10 PSI (0.7 kg/ at thenozzle tip.Spraying into a bucket for one minute and measuring thequantity of the suspension in a graduated mug should checkthe correct discharge rate (740 to 850ml/minute).The nozzle tip should be discarded if the discharge rateexceeds 850 ml per minute.Important points to be remembered duringIRS
  • 37. If the spray stops due to a blockage in the nozzle, the nozzlecap be unscrewed to remove the blockage and replaced with anew one.The blocked nozzle should be put in a container with waterfor a few hours before the blockage is removedA good quality spray should lead to uniform deposit on wallsand other sprayable surfaces. This is easy to verify for DDTon sprays as the insecticide deposits are clearly visible.The supervisor through physical verification should verify thequality and coverage of spray randomly.It takes about 5 minutes to spray a house with an averagesurface area of 150 sq. metres.Important points to be remembered duringIRS
  • 38. Concurrent supervisionThe following should be checked during such inspections:•Date of advance notification and the maintenance of time table for sprayoperations•Turn out of spray crew•Nozzle tip discharge rate•Conditions of spray pumps•Preparation of insecticide suspension•Actual spraying operation including the technique, speed and coverage etc.•Extent of refusal to accept spray and the numbers and percentage oflocked houses•Maintenance of spray records•Consumption of insecticide as determined by the quantity issued and stockin hand•Date and time of checking of the squad by Inspectors/ Supervisors andother supervisory personnel and their remarks, if any•Arrangements for mopping up•Future programme and time schedule
  • 39. Consecutive supervisionThe following is to be checked in consecutive supervision•Evidence of insecticide deposit on sprayable surfaceparticularly on the ceiling and wooden material like windowsetc.•Dispersal of the insecticide deposits on the walls to verifyuniformity of deposits•Number of rooms in each house sprayed satisfactorily,partially and not at all•Percentage of refusals and locked houses•Factors responsible for not spraying any area as elicitedthrough enquiries from the residents•Attempts made for mopping up operation in the event ofhigh refusal•Extent of mud plastering on the walls, if any and otherrelevant matters.
