In the last week of May, heavy rainfall and flooding were registered across the states of Pernambuco and Alagoas in northern Brazil. In Pernambuco, 24 out of 185 municipalities have declared state of emergency: 55,000 have been displaced and up to 2.2 million temporarily affected by damage to WASH infrastructure. In Alagoas, the highest estimates are of 16,000 people displaced and 27 out of 102 municipalities in state of emergency.

Since late September, several armed clashes between government forces and militia Nsilulu, also known as Ninja, have occurred in Pool Department. According to the government, more than 60 fatal attacks have been carried out. According to the latest census in 2007, more than 126,000 people are living in these areas and have been affected by the conflict. At least 23,000 people have been displaced since March 2016. 

Since 23 May, fighting has erupted in Marawi city, Lanao del Sur on Mindanao island. As of 1 June, over 100,000 IDPs have been registered by the regional authorities since 23 May but up to 90% of the 201,000 residents of Marawi are estimated to have fled. 

Cyclone Mora made landfall near Kutubdia upazila, Cox’s Bazar district, southeast Bangladesh on 30 May. Initial assessments estimate that over 280,000 people have been affected. Vulnerable settlements where refugees and undocumented migrants and refugees, many of whom are Rohingya, reside in Cox’s Bazar have been hit particularly hard. 

Heavy rains in southwestern Sri Lanka from 25 May triggered flooding that affected 15 districts, of which Galle, Kalutara, Matara, and Ratnapura were the most severely affected. Over 588,000 people have been affected, 180 killed, and 110 are missing. Landslides and flooding have constrained access to heavily affected areas. 

Fighting in and around the Kasai regions continues to cause displacement. So far, approximately 1.3 million people have fled violence in eight provinces. Between April and 22 May, over 23,500 people arrived in Angola. By mid-April 2017, at least 400 deaths had been recorded, including many civilians, but the number is likely higher. 

Floods during the rainy season from June until at least October will affect about 200,000 people, mostly in southern Sudan. Particularly vulnerable are the displaced in southern Sudan, where there are 2.3 million IDPs and about 400,000 South Sudanese, 110,000 of whom arrived in 2017. Floods will damage key WASH infrastructure and increase the caseload of diseases including cholera and malaria.

6.9 million people are living in areas with inadequate health services in the northeast, including more than 68% of the 1.8 million IDPs living in host communities across Adamawa, Borno, and Yobe states. The lack of qualified staff and essential medicines, and the destruction of medical facilities all continue to hamper the implementation of interventions.   

About 150,000 people are facing famine in Nigeria and South Sudan. Another 9 million face Emergency food security outcomes (IPC 4) in Nigeria, Somalia, South Sudan, and Yemen, and could face Famine (IPC 5), if no assistance is provided between May and August, when the lean season takes hold.

A spike in fighting over resources occurred in Alindao, Basse-Kotto over 7–9 May, with at least 56 people killed and over 11,000 displaced. In nearby Bangassou, Mbomou prefecture, armed groups killed at least 26 people, with at least 3,000 displaced in CAR, 2,750 fleeing to DRC and 25,000 in need of humanitarian assistance. 

A cholera outbreak was reported in Yemen on 27 April. Since then, the number of acute watery diarrhoea or suspected cholera cases has increased to reach over 17,200, including 209 deaths, and the infection rate is rising quickly. The outbreak has affected 18 districts: Sana’a City is the most heavily affected area, with over 4,000 suspected cases. A state of emergency has been declared in the governorate.  

Import restrictions from the economic crisis that escalated in 2014 are resulting in severe food shortages and escalating malnutrition rates. A recent assessment of 526 children in several states found GAM rates of 8.9% and SAM of 3.2%. Severe medicine shortages combined with poor hospital services facilitate the spread of diseases such as malaria and diphtheria. 

Between 9 January and 25 April, a total of 164 cases of hepatitis E, including 25 deaths (CFR: 15.2%) have been reported in Diffa region, where there is a population of about 670,000. The outbreak was declared by the Nigerien authorities in mid-April. All the deaths occurred among pregnant mothers. 

Timor-Leste has been experiencing a severe drought due to the El Niño phenomenon since the end of 2015. The latest rainy season, which takes place from November 2016 to May 2017, has been insufficient and erratic, maintaining drought conditions on most of the island. In the next three months, rains are expected to remain insufficient with the onset of the dry season in June. 

Since August 2016, armed clashes have occurred in Kasai-Central, Kasai Oriental, Kasai, Lomami, and Sankuru.

Regionally, around 330,000 hectares of staple crops, especially maize, have been affected. The remaining southern African mainland countries remain at high risk. 

Many rural areas of Sindh are currently experiencing daily highs above 40°C, which are forecast to continue until early May. Heatwaves in the past have caused considerable health impacts including dehydration, sunburn, and heatstroke. Impacts on WASH lead to additional health risks such as waterborne diseases.

Years of insurgency and counterinsurgency operations have resulted in the displacement of approximately 1.9 million people and created a food and nutrition crisis in Nigeria’s northeast. The worst-affected local government areas of northeast Nigeria are facing Emergency (IPC Phase 4) food security conditions and Global Acute Malnutrition (GAM) levels above emergency threshold.

3,959 cases of meningitis, 181 laboratory confirmed, resulting in 438 deaths have been reported as of 5 April. While 19 states have reported outbreaks, 97% of reported cases are in six states: Katsina, Kebbi, Niger, Sokoto, Yobe, and Zamfara. Meningitis serotype C, or NmC, is responsible for 83% of laboratory confirmed cases and is severely undervaccinated in the affected areas. 

130mm of rain fell in the city of Mocoa in southwest Colombia on 1 April local time, causing the flooding of the Mocoa, Mulato, and Sangoyaco Rivers, and several mudslides throughout Mocoa.
