Brazil has reported 83 cases and 28 deaths from yellow fever since 24 January 2018. These cases occurred in São Paolo (47), Minas Gerais (27) and Rio de Janeiro (9) states. The total from July 2017 to 30 January 2018 now stands at 1 080 cases. Of these, 213 cases are laboratory confirmed, with 81 deaths.
Media quoting Brazilian health authorities advise visitors to the Rio de Janeiro Carnival avoid sightseeing at waterfalls and forests, as these areas present a risk of yellow fever transmission. Authorities say the risk remains low in Rio de Janeiro city.
Recent expansion of yellow fever into the municipality of Sao Paulo and the municipalities of Greater São Paulo (Cajamar, Caieiras, Mairipora, Franco da Rocha, Guarulhos, and Itapecerica da Serra), indicate high risk for non-immunized people. The World Health Organisation (WHO) considers all of São Paulo State as being at risk of yellow fever transmission.
There is a widespread risk of yellow fever in Brazil, including São Paulo City.
Yellow fever risk areas in Brazil are shown below.
A traveller’s risk of yellow fever is determined by their general risk assessment e.g. country visited, length of stay, city or rural, activities etc.
Mosquito bite avoidance rules should be adhered to at all times – the mosquito that spreads yellow fever bites predominantly during the day. Click here for taking precautions against mosquito bites.
Yellow fever vaccine is recommended for travellers to areas at risk of yellow fever (including São Paulo City) unless contraindicated.

A dog with rabies loses territorial instincts and may wander long distances and so shows up unexpectedly and is called “Stray”.
However, studies have shown there is no significant stray dog population in KZN. Therefore, almost all rabid dogs were owned but unvaccinated and so contracted the disease.
Dogs are transported by people all over the country, and with a longish incubation normally 2 weeks or longer, can appear anywhere at any time. Rabies has been found in Johannesburg having come from KZN before. This means that although we consider some areas more dangerous than others it could pitch up anywhere.
Therefore, a message of caution especially to children must be spread abroad to avoid contact with any unknown dog or animal that is acting strangely.
Rabies is the most fatal disease known to man, once the virus attaches to a nerve cell (which they like) it is 100% fatal with no treatment available once symptoms start.
It is however 100% preventable with the correct treatment is given when the bite happens (Therefore timing is everything).
The incubation period can be from 10 days to two years.
It is one of the most horrific ways to die. It can appear as demon possession and brings fear to the whole community. All victims will die in a few days following the start of symptoms, fully aware of what is happening.
A dog bite in KZN is seen as an emergency and an ambulance can be called if transport is problem.
Treatment consists of four injections on day 0;3;7;14 which MUST BE COMPLETED!!!!
If a bad bite, additional injections will be done into the wound.
Travel Doc offers a Rabies Vaccination. In South Africa this vaccination is recommended for people with potential for occupational exposure eg. veterinary staff, wild life handlers, lab personal working with rabies virus and animal welfare staff. The vaccination is also recommended for long term travelers to high risk areas in South Africa especially for young children living close to the local population and their dogs.
For overseas travel: rabies vaccinations is not advised for routine overseas travel however it should be considered for travelers visiting regions in the world where canine rabies regularly affects animals and where contact with animals is probable and immediate access to appropriate treatment is limited – such as travel in the backpacking or adventure category (adventure travel to Asia, Indian sub-continent, South America or trans-Africa overland trips).

The World Health Organization has revised countries requiring Yellow Fever Vaccinations. Travelers going to or coming from Zambia, Tanzania, Eritrea, Somalia, Sao Tome and Principe as well as Rwanda will no longer be required to produce a yellow fever vaccination certificate when in South Africa as these countries have been included on the World Health Organization (WHO) list of countries with low potential for exposure to yellow fever.
During the 136th session of the WHO Executive Board meeting, a review of countries with risk of yellow fever transmission and countries requiring yellow fever vaccination was conducted and based on the recommendations of the meeting; all travelers arriving into South Africa from these countries will NOT be required to produce proof of vaccination against Yellow Fever. This provision is with immediate effect.
In line with the International Health Regulations, 2005 South Africa requires a valid yellow fever certificate from all citizens and non citizens over one year of age (citizens over 60 years of age require a waiver certificate) if they are:
· Travelling from a yellow fever risk country; or
· Have been in transit exceeding 12 hours, through the airport of a country with risk of yellow fever transmission.
Vaccine should be approved by the WHO and administered at least 10 days before departure to South Africa at a Yellow Fever approved vaccination centre. The vaccine offers protection 10 days after administration and provides lifetime immunity.

Yellow fever virus is found in tropical and subtropical areas in South America and Africa. The virus is transmitted to people by the bite of an infected mosquito. The mosquito responsible for spreading Yellow Fever is from the Aedes and Haemogogus species.
Once contracted, the yellow fever virus incubates in the body for 3 to 6 days. Many people do not experience symptoms, but when these do occur, the most common are fever, muscle pain with prominent backache, headache, loss of appetite, and nausea or vomiting. In most cases, symptoms disappear after 3 to 4 days.
A small percentage of patients, however, enter a second, more toxic phase within 24 hours of recovering from initial symptoms. High fever returns and several body systems are affected, usually the liver and the kidneys. In this phase people are likely to develop jaundice (yellowing of the skin and eyes, hence the name ‘yellow fever’), dark urine and abdominal pain with vomiting. Bleeding can occur from the mouth, nose, eyes or stomach. Half of the patients who enter the toxic phase die within 7 – 10 days.
Yellow fever is difficult to diagnose, especially during the early stages. More severe disease can be confused with severe malaria, leptospirosis, viral hepatitis (especially fulminant forms), other haemorrhagic fevers, infection with other flaviviruses (e.g. dengue haemorrhagic fever), and poisoning. It is imperative to visit Travel doc – Travel Clinic should you experience any of these symptoms when returning from a yellow fever area.

Yellow fever virus is found in tropical and subtropical areas in South America and Africa. The virus is transmitted to people by the bite of an infected mosquito. Illness ranges in severity from a self-limited febrile illness to severe liver disease with bleeding.
1) Use insect repellent.
2) Wear proper clothing to reduce mosquito bites.
3) Be aware of peak mosquito hours: peak biting times for many mosquito species is dusk to dawn. However, one of the mosquitoes that transmits yellow fever virus, feeds during the daytime.
4) Yellow fever vaccine is recommended for people aged ≥9 months who are traveling to or living in areas with risk for YFV transmission in South America and Africa. In addition, some countries require proof of yellow fever vaccination for entry.
