There are some diseases, known as “infectious diseases,” that you can catch from somebody or pass onto other people without knowing it.

2. 1. I have a bad cough. What kind of illness might I have?

• Coughs can have various causes.
• If you have symptoms such as a prolonged cough, blood in your phlegm, low-grade fever, weight loss, or listlessness, it may be tuberculosis. In that case, you should be examined by a doctor immediately.
• When COVID-19 is spreading, think about getting tested soon, such as being seen at a hospital.
COVID-19 and tuberculosis both cause coughs, shortness of breath, fever, and listlessness.The biggest difference is the speed of progression of the disease. With tuberculosis, only one or two people for every ten people infected develop symptoms, and it often takes from several months to around two years for symptoms to become apparent.However, with COVID-19, symptoms start within a few days of infection. In both cases, once symptoms appear, be quick to get tested and be seen at a hospital.

2. 2. What will happen if I am diagnosed with tuberculosis?

• Tuberculosis is a disease that can be cured with medicine.There is assistance for 95% of medical expenses from public funds.
You will only have to pay 5% of your medical expenses
• Be sure to comply with the instructions of the doctors at the hospital.
If your symptoms are mild, once you start treatment,
you will be able to work normally while being treated as an outpatient.
There is no need for you to go home to your country.
If your symptoms are severe,
you may need to be hospitalized temporarily.
The usual duration of treatment is six months, but it can be longer.

With tuberculosis of the lungs, you may infect other people, but usually, about two weeks after you start treatment, you will no longer be contagious.
There are also types of tuberculosis (called latent tuberculosis) that have no symptoms and that there is no possibility of infecting others.

Tuberculosis is a disease that can be cured with the right treatment. If you are not emitting the bacteria from your body and you are receiving the correct treatment, in many cases, you will be able to keep working without infecting other people. Also, the public office will investigate close contacts of people who have been diagnosed with tuberculosis, so please cooperate with these investigations.

What is a public health state of emergency?
As you all experienced with the COVID-19 pandemic, amid the progress of globalization, public health emergencies have become a major problem both nationally and globally.Public health emergencies can cause outbreaks of disease, natural disasters, serious injury to people, and loss of life.A certain situation will become a state of emergency when society is no longer functioning well enough to take countermeasures against the situation’s impact on health.
The following are some examples.
• Outbreaks of infectious disease; influenza pandemic, measles, avian influenza, COVID-19, etc.
• Natural disasters’ impact on health: earthquake, tsunami, flood, typhoon, etc.
• Accidents that cause many casualties: Airplane crash, train derailment, etc.
• In Japan, outbreaks (increase in the number of people infected) of measles, rubella, and influenza have been reported. When there is an outbreak, measures to prevent infection (washing hands, wearing masks, etc.) and vaccines are beneficial.
Regarding influenza, there are outbreaks every winter in Japan, so in some cases, the company may subsidize the cost of influenza vaccination.
If a public health emergency occurs, it is important to gather information from the Japanese government, local governments, news, and other sources.
