Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically beg...in three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.

Chikungunya virus (CHIKV) is a re-emerging mosquito borne alphavirus responsible
for the recent outbreak in the Americas. Immunologically naïve population in the Americas favors the spread of epidemics. Chikungunya fever is characterized by an abrupt febrile illness, polyarthralgia and maculopapul...ar rash. In chikungunya fever, shock or severe hemorrhage is very rarely observed; the onset is more acute and the duration of fever is shorter than dengue disease. The pain is much more pronounced and localized to the joints and tendons in chikungunya fever, in comparison to dengue fever. There is no specific and effective antiviral therapy and vaccines are still in trails. The only effective preventive measures consist of individual protection against mosquito bites and vector control. Disease prevention is important due to the
economic burden it entails. Clinicians need to distinguish chikungunya fever between dengue fever and other diseases to give a successful treatment and prevent disease spreading.

Lao People’s Democratic Republic (Lao PDR), also referred to as Laos, or Lao, is exposed to natural disasters such as flooding, typhoons, cyclones, drought, and earthquakes. The country is vulnerable to recurrent, sudden-onset and slow onset natural disasters with flooding, storms and typhoons hav...ing a large effect on the population. The country remains highly vulnerable to agricultural shocks and natural disasters.
Lao has established Community Based Disaster Risk Reduction (CBDRR) practices as a result of the many natural disasters the country faces. CBDRR is implemented at the village level to enhance community preparedness and to decrease village vulnerabilities to disasters.
Lao established the National Disaster Management Committee (NDMC) as its national disaster management platform and the National Disaster Management Office (NDMO) to be responsible for DRM (Disaster Risk Management) and DRR activities in the country.

Women, the elderly, adolescents, youth, and children,
persons with disabilities, indigenous populations, refugees,
migrants, and minorities experience the highest degree
of socio-economic marginalization. Marginalized people
become even more vulnerable in emergencies.1 This is due
to factors su...ch as their lack of access to effective surveillance
and early-warning systems, and health services. The
COVID-19 outbreak is predicted to have significant impacts
on various sectors.
The populations most at risk are those that:
• depend heavily on the informal economy;
• occupy areas prone to shocks;
• have inadequate access to social services or political
influence;
• have limited capacities and opportunities to cope and
adapt and;
• limited or no access to technologies.
By understanding these issues, we can support the capacity
of vulnerable populations in emergencies. We can give
them priority assistance, and engage them in decision-making
processes for response, recovery, preparedness, and
risk reduction.

In 2021, the humanitarian community continued to support those in need, placing protection at the centre of its response. Learning from and building on past efforts, humanitarian actors will continue to respond and adapt their response to the various shocks impacting populations in Cameroon, such as... violence against civilians, natural disasters, and epidemics, including the COVID-19 pandemic.

The United Nations Children's Fund (UNICEF), the International Organization for Migration (IOM), Georgetown University, and the United Nations University have today launched new guidelines to provide the first-ever global policy framework that will help protect, include, and empower children on the ...move in the context of climate change.
The Guiding Principles for Children on the Move in the Context of Climate Change provides a set of 9 principles that address the unique and layered vulnerabilities of children on the move both internally and across borders as a result of the adverse impacts of climate change. Currently, most child-related migration policies do not consider climate and environmental factors, while most climate change policies overlook the unique needs of children.
The guidelines note that climate change is intersecting with existing environmental, social, political, economic, and demographic conditions contributing to people’s decisions to move. In 2020 alone, nearly 10 million children were displaced in the aftermath of weather-related shocks. With around one billion children – nearly half of the world’s 2.2 billion children – living in 33 countries at high risk of the impacts of climate change, millions more children could be on the move in the coming years.
Developed in collaboration with young climate and migration activists, academics, experts, policymakers, practitioners, and UN agencies, the guiding principles are based on the globally ratified Convention on the Rights of the Child and are further informed by existing operational guidelines and frameworks.
Recommendations for safeguarding the rights and well-being of children regardless of their location or migration status.
The guiding principles provide national and local governments, international organizations and civil society groups with a foundation to build policies that protect children’s rights. The organizations and institutions are calling on governments, local and regional actors, international organizations, and civil society groups to embrace the guiding principles to help protect, include, and empower children on the move in the context of climate change.

Prescriptions and Actionables for a Healthy and Green Recovery.
The practical steps outlined in this report aim at creating a healthier, fairer and greener world while investing to maintain and resuscitate the economy hit by the effects of COVID-19.
Policy makers, national and local decision-make...rs and a wide array of other actors wishing to contribute to a healthy recovery can now take decisive steps by shaping the way we live, work and consume. Effects on environmental degradation and pollution and climate change will be wide ranging. WHO and partner organizations have since long been developing substantive guidance and provide support for building healthier environments for healthier populations.
