    Circulation of Rift Valley Fever in Mayotte

    Press release
    Prevention Health Watch & Epidemiology 17 January 2019

    Infectious disease, of viral origin, Rift Valley Fever (RVF) mainly affects domestic ruminants (cattle, sheep, goats), but can occasionally contaminate humans. Since November 22, 2018, five human cases of Rift Valley Fever have been reported by the laboratory of the Mayotte Hospital Center to the LRA.

    These 5 cases, grouped together over time, indicate a new circulation of the virus in Mayotte. The Indian Ocean Health Agency and the Directorate of Food, Agriculture and Forestry of Mayotte (DAAF) remind us that population the importance of implementing prevention recommendations and actions to avoid contamination.
    ...
    Epidemiological situation

    The existence of a circulation of the Rift Valley Fever (RVF) virus has been known in Mayotte since 2007, following the identification of a first human case on the territory. Following this report, the setting up of a retrospective and prospective surveillance had allowed to find a dozen human cases between 2007 and 2013.

    Among the livestock in Mayotte, for the past ten years, RVF has been monitored through epidemiological surveillance networks. This follow-up showed a steady decrease in seroprevalence until June 2018.
    In the second half of 2018, seroprevalence again increased significantly.

    Since 22 November 2018, five human cases of Rift Valley fever have been reported by the CHM laboratory to the LRA. These 5 recent cases indicate a probable new circulation of the virus in the herds of Mayotte. Indeed, none of the 5 sick people had traveled outside Mayotte during the incubation period of the disease.

    Epidemiological Point N ° 03 of 30/01/2019
    ...

    | Epidemiological Situation in Human Health as of January 28, 2019 |

    As of 28/01/2019, 19 RVF cases were reported to the watch and emergency platform of the ARS OI (CVAGS) by the CHM laboratory. The first case was on the 11th December 2018 (week 50-2018) and the next 4, diagnosed between 26/12/2018 and 03/01/2019, were reported in weeks 52-2018 and 01-2019 (Figure 1). Since, 14 new cases were reported in weeks S03-2019 (2 cases), S04-2019 (8 cases) and S05- 2019 (4 cases). These cases were confirmed by PCR in the CHM laboratory with a double confirmation for the first case by the associated CNR of Reunion arboviruses. On January 15th, 4 other samples were transferred to the CNR of the arboviruses of Marseille. The investigations carried out around these cases showed that they were all acquired locally.

    ...
    The 19 confirmed cases were mostly men (14 men and 5 women), between 27 and 64 years old. Investigation by the Anti-Vector Control Service (LAV) of the ARS OI could be carried out for 14 cases and 10 of them answered the questionnaire epidemiological investigation. In addition to fever (greater than 38.5 ° C), the 10 cases who responded to the questionnaire reported myalgia (4 cases), headache (6 case), asthenia (4 cases), arthralgia (5 cases) and stiffness of the neck (3 cases). The investigations carried out by the LAV service and the CVAGS of the ARS OI have shown that the majority of cases were in direct contact with animals (breeders) or lived close to farms including cattle and goats (9 cases), while 5 cases reported not to be in contact with animals. Two cases reported consuming sometimes raw milk from these animals.

    Geographical distribution of cases

    The first reported case of FVR resides in the commune of Mamoudzou while 11 of the 19 cases reside in the communes of the west central island of Tsingoni (3 cases), Ouangani (2 cases), Chiconi (5 cases) and Sada ( 1 case). Five resident cases in 2 communes of the North of the island: 3 cases in Mtsangamouji, 2 with family ties and 2 cases residing in the municipality of Mtsaboro in the villages of Mtsahara and Handréma, relatively far from the place of residence of the other cases (Figure 2). Information on place of residence was not available for 2 cases.
    The investigations carried out around the first 5 cases showed that all would have had direct or indirect links with the Ouroveni area before the onset of symptoms. It is an agricultural zone located between the villages of Combani and Chiconi, where 9 of the 19 confirmed cases live (hiking, owning a field or livestock in the area ...). No direct or indirect link was found between the Ouroveni area and the 9 other distant cases in this area.
    ...
    | Epidemiological situation in animal health |

    Samples made on ruminants present around human cases were analyzed at CIRAD in Réunion for the search for the RVF virus. The results identified several positive animals in different villages located in west and center of the island (Figure 2). In addition, a positive IgM cattle has been reported to Mamoudzou. This is a cattle 2 years old belonging to a breeding of 8 cattle including 4 adults and 4 calves of 2 months. Biological control and investigations are underway. According to data from the Mayotte breeders cooperative and CIRAD, the seroprevalence of RVF, which has not stopped to drop in Mayotte from 2008 to 2017, seems to have increased significantly between the period 2017-2018 (3.6%, 95% CI [2.3; 5.6]) and the period 2018-2019 (10.1% 95% CI [6.5, 15.3]). The end of 2018 marks a break in the the decrease in seroprevalence observed since 2008. This trend is to be confirmed in 2019.

                        Rift Valley Fever – Mayotte (France)

                        Disease outbreak news
                        13 May 2019


                        On 4 January 2019, the National IHR Focal Point for France informed WHO of five human autochthonous cases of Rift Valley Fever (RVF) diagnosed on Mayotte Island through the Early Warning and Response System of the European Union. The dates of symptom onset ranged from 22 November to 31 December 2018.
                        From November 2018 to 03 May 2019, 129 confirmed human Rift Valley Fever (RVF) cases and 109 animal foci (23 small ruminants and 86 bovine) have been reported in Mayotte. After a steady decline in cases during the last three weeks of March 2019, a slight increase has been observed in April 2019. As of 3 May 2019, one new human case but no new animal foci have been reported. Both human RVF cases and animal foci are mainly located in the center and the north west of the main island Grande-Terre. However, since the end of March 2019, a few new animal foci have also been detected in the east of Grande-Terre and in Petite Terre of Mayotte.
                        Public Health Response

                        The following actions have been taken since the detection of the human cases in January 2019:
                        • Enhanced surveillance of both human and animal health has been implemented by the local health authorities.
                        • Meetings between human and animal health experts have been held locally and at national level for disease information exchange.
                        • Local health authorities supply regular communications to breeders and the population to remind them about the importance of personal protective measures against mosquito bites, and avoiding consuming raw meat and milk for infection prevention.
                        • Raising awareness among health workers to rapidly diagnose cases.
                        • Commercialization of raw milk has been forbidden since 27 February 2019.
                        • Exportation of cattle and raw meat and milk from Mayotte is also forbidden since 20 March 2019.
                        WHO risk assessment

                        RVF virus has been circulating actively on the island of Mayotte, in a context of regular import of the virus from nearby countries through illegal animal movements, the presence of susceptible animals and a favorable environment for mosquito vectors to maintain virus transmission locally. RVF virus is primarily transmitted by mosquitoes mainly belonging to the Aedes and Culex genera (but also Anopheles, Mansonia and other mosquito species) among animals. Mayotte, has a notable species richness of mosquitoes with 45 documented species belonging to 15 genera including Aedes and Culex which act as reservoirs of RVF virus. The risk of mosquito borne infections in animals should decrease in the coming months as the rainy season (December to April) in Mayotte is over. However, prolonged rain linked to post-cyclone Kenneth may lead to an increase in RVF cases.
                        While the main route of infection of humans is through direct or indirect contact with the blood, body fluids, tissues and organs of infected animals and aborted animal fetuses, it is highly contagious for humans when handling infected livestock. The high-risk groups including veterinarians, livestock farmers and butchers should conduct safe animal husbandry and slaughtering practices to prevent infections. To date, no human-to-human transmission of RVF virus has been reported.
                        The RVF epizootic can cause agricultural impact and economic losses to communities due to high mortality and abortion rates among infected livestock, loss of public trust in safety of animal products (milk, meat) or bans of movement that might be put in place to control this outbreak. Local authorities have implemented appropriate control measures and strengthened the multisectoral One Health approach to prevent, detect and respond to the RVF outbreak. Nevertheless, there are concerns about a potential increase of cases and foci in May 2019, because of the Ramadan period where an increase of illegal cattle importations is expected. To date, there is no information suggesting the disease will spread beyond Mayotte.

                        RVF is a viral zoonosis that primarily affects domestic animals (including cattle, sheep, camels and goats) and to a lesser extent human. The RVF virus is highly contagious for humans when handling potentially-infected livestock. Raising awareness of the risk factors of RVF transmission as well as protective measures such as vector control and protection against mosquito bites is the key to reduce human infection and deaths. Public health messages for risk reduction should focus on:
                        • Reducing the risk of animal-to-human transmission because of unsafe animal husbandry and slaughtering practices. Practicing hand hygiene, wearing gloves and other appropriate individual protective equipment when handling sick animals or their tissues or when slaughtering animals.
                        • Reducing the risk of animal-to-human transmission arising from the unsafe consumption of fresh blood, raw milk or animal tissue by thoroughly cooking before eating.
                        • The importance of personal and community protection against mosquito bites by using impregnated mosquito nets, personal insect repellent if available, light-colored clothing (long-sleeved shirts and trousers) and by avoiding outdoor activities at peak biting times of the vector species.
                        • As outbreaks of RVF in animals precede human cases, the establishment of an active animal health surveillance system is essential in providing early warning for veterinary and human public health authorities. Routine animal immunization in endemic areas can prevent RVF epizootics. Vaccination campaigns are not recommended during an outbreak as it may intensify transmission among the herd through needle propagation of the virus.
                        WHO does not recommend any restriction on travel to, and trade with Mayotte based on the current information available on this event.
