Typical symptoms of TB include:
a persistent cough that lasts more than three weeks and usually brings up phlegm,
which may be bloody
weight loss
night sweats
high temperature (fever)
tiredness and fatigue
loss of appetite
new swellings that haven't gone away after a few weeks
How TB is treated
With treatment, TB can usually be cured. Most people will need a course of antibiotics,
usually for six months.
Several different antibiotics are used. This is because some forms of TB are resistant to
certain antibiotics. If you are infected with a drug-resistant form of TB, treatment with six or
more different medications may be needed.
If you are in close contact with someone who has TB, tests may be carried out to see if you
are also infected. These can include a chest X-ray, blood tests, and a skin test called the
Mantoux test.
26. Yellow fever:
Yellow fever is a serious viral infection that is spread by certain types of mosquito. It’s
mainly found in sub-Saharan Africa, South America and parts of the Caribbean.

travelers.
Yellow fever symptoms
The symptoms of yellow fever occur in two stages. The initial symptoms develop three to six
days after infection, and can include:
a high temperature (fever)
a headache
nausea or vomiting
muscle pain, including backache
loss of appetite
Treating yellow fever
There is no specific treatment for yellow fever, but the symptoms can be treated while your
body fights off the virus.
