The National Vector Borne Diseases Control Programme functions as per the guidelines laid down by the NCVBDC, Govt. of India to prevent and control vector borne diseases like Malaria, Filaria, Dengue, Chikungunya& Japanese Encephalitis in strategies involved for control of vector borne diseases:-

• Early detection and prompt & complete treatment.
• Surveillance measures including active and passive.
• Integrated vector control measures comprising of both Anti-Larval and anti-adult measures.
• Bio-environmental control measures comprising of supply fish introduction as an effective antilarval measure to reduce vector pressure.
• Source reduction by simple physical methods and cleanliness drives in the community.
• Promotion of personal protection methods namely use of insecticides treated bednets, use of mosquito repellants, etc. to prevent man-mosquito contact.
• Behaviour Change Communication strategies to create mass awareness.

The State of Goa is in the elimination phase of Malaria, expected to eliminate Malaria by 2023-2024. As per Government of India, Annul Parasite Incidence is the indicator for categorization of states for malaria elimination. State of Goa has API <1 at the state as well as at district level.

Total Health units are 34 out of these all peripheral centres have achieved zero indigenous status in the year 2023-24 till date.

During the year 2022, there was a decline in the malaria cases due to following reasons :

• Regular Monitoring of Vector Borne Diseases at the highest level, State level Committee for Vector Borne Disease meetings under the Chairmanship of Secretary (Health).
• Screening of Rokhda labourers for early detection and prompt treatment at construction sites.
• Use of Ultra Low Volume (ULV)& thermal fogging machine by use of Pyrethrum Aquafog and Pyrethrum 2% ext. in and around high risk areas respectively.
• Regular anti-larval activities by use of Temephos & MLO.
• The facility for detection of malaria with Rapid Diagnostic kits is extended to all the health centres in the state so that immediate results are obtained for treatment of labourers.
• Information, Education, Communication/Behaviour change Communication measures were taken up at all level with the involvement of Local bodies, NGOs and community at large by organizing advocacy, Inter-sectoral meetings and other Information, Education and Communication programme.

Focal cases of Dengue and Chikungunya are reported all over Goa and these are now under control due to sustained source reduction measures carried out with the involvement local bodies.

Above activities are carried out throughout the year for prevention and control of Vector Borne Diseases.
