Readers in the areas affected by the swine flu outbreak have been sending their accounts to the BBC since the first cases were reported.
The virus - which has so far claimed more than 100 lives in Mexico - has spread, with the first European case confirmed in Spain.
Governments around the world are attempting to prevent it spreading further, amid reports of further infections in the US and Canada.
Below, a selection of BBC readers' comments describe a sense of fear and uncertainty gripping their countries as a result of the spread of the virus.
I'm a doctor responsible for managing vaccines in the northern Mexican state of Nuevo Leon.
Over the last two weeks we started seeing patients with high fever, muscle aches, sore throats and coughs. Those symptoms seemed a bit odd for us, but we didn't diagnose them with swine flu as we didn't know about it.
On Sunday we had our first death in the area. It was someone who came from Mexico City. But we don't have the means to confirm whether it was as a result of swine flu.
More than anything, we lack equipment and laboratory kits. All we can do is look at the symptoms and make a clinical diagnosis.
In the pharmacies, there is no Tamiflu available. They only have another medication and they don't even have enough of that.
So the vaccines we have are not enough we don't have the medication required. People here are not aware that this flu outbreak can kill people.
On behalf of all the medical community in Nuevo Leon I'd like to ask for help to get the medication, so we can treat people.
We need to have the means to diagnose people and, most importantly, the means to offer them treatment. Dr Vicente Torres, Monterrey, Nuevo Leon, Mexico
I have been trying to purchase face masks for myself and my family - my wife and two children - but haven't been able to get one anywhere.
I have visited six pharmacies in the area and all are sold out. None are expecting deliveries until Tuesday. I am concerned by this and don't think it's good enough, given it's a measure the government is advising.
However, I haven't seen any clear government advice on where people can get masks.
My family and I are all at home and are taking general precautionary measures - such as avoiding any outside contact, going very carefully to the supermarket to do basic shopping and making no unnecessary visits or trips.
I hope the government is being truthful - it certainly appears to be transparent in its information.
The schools are closed, as are public buildings. People have been advised to stay at home and have been instructed with basic health precautions to take. Jorge, Mexico City, Mexico Our health minister has just confirmed a positive case in a small town called Almansa, 50 miles from the capital of the province of Albacete, where I live.
There are other suspected cases in the same province. It is very worrying, especially as there are concerns that the numbers of people infected will grow.
The main hospital for the province is here in my town and people will be coming here for treatment.
We have received no further information yet from the authorities, beyond the case being confirmed.
We have just been told to stay calm. Meanwhile, everybody is texting each other asking what next? Francisco Cebrian, Albacete, Spain
I am a doctor and I work in the State of Mexico. I don't work in the shock team; I am in the echocardiography team, but I do get some news from my colleagues in the hospital. There have been some cases of young people dying from respiratory infections, but this happened before the alert and they were not reported because the necessary tests weren't done. We doctors knew this was happening a week before the alert was issued and were told to get vaccinated. I went to buy some anti-virals for my husband, who is also a doctor, because he had contact with a young patient who presented influenza symptoms and died. I don't think pharmacies stock enough anti-virals.
I understand the government doesn't want to generate panic, but my personal opinion is that they issued the alert too late. Still now, the population is not getting the information they need. We have been out in the street and some people are not wearing face masks and are not taking any preventive measures. Guadalupe, Mexico City This is another blow to the tourism industry in Mexico, even though non of the events that is taken place is anywhere near the tourist areas of Cancun, Playa del Carmen or Puerto Vallarta, the news comes across as all of Mexico is affected! After wrong reports of drug related violence, military presence etc. in Cancun, which hurt the industry tremendously, now people think that all of Mexico is affected by a virus that is mostly present in the capital. I guess the problem is that this is a country where the capital carries the same name as the country, thus when people hear news about Mexico, albeit it refers to Mexico City, they assume it is affecting the whole country.

中国の情報工作は、積極的に何かを仕掛けるばかりではない。弱みを掴んで材料を仕込んだ上で、取引を持ちかけるケースもままある。顕著な例は日本の大手メディア対策だ。中国の工作機関にとって、メディアは最初に攻略しておかねばならないターゲットであり、手なずけておいて、中国を利するような情報を流して大きく報道してもらったり、逆に中国に不都合な情報を掴まれた場合は、相手に不利な情報をちらつかせ、脅し、情報そのものを潰してしまう。脅しにかけられ、それに屈した中国駐在の日本人特派員は二人や三人ではないという。

ロシアがアラスカを狙い部隊を再編成しています。大日本帝国滅亡時に満州国を攻め込んだ歴史を思い出して下さい。北方領土や満蒙開拓団の悲劇はその時に始まりました。

アテナイはペリクレスの提案によって、城塞外に居住する市民全てをアテナイとペイラエウス港及び両者を繋ぐ二重城壁の内側へ退避させる篭城策を取り、海上よりペロポネソス同盟の本国などを攻撃する作戦を取った。ところが人口が急激に増加した市内に疫病が発生し、紀元前429年までに市民の約3分の1が病死し、ペリクレスも病死した。
しかし海上におけるアテナイ軍の優位は変わらず、紀元前425年のスファクテリアの戦いにおいて従来決して降伏しないとされていたスパルタ市民兵120人を含む292人を捕虜とする勝利を収めるなどしていた。このことからペロポネソス同盟軍側は停戦を申し入れたが、ペリクレス死後、好戦的なデマゴーグなどの指導者しかいなかったアテナイはこの申し出を拒否し、徹底抗戦の構えをとった。

映画「ナショナル・トレジャー2 大統領の秘密の本」を見てください。リンカーンを暗殺したのは、ゴールデン・サークル騎士団(Knights of the Golden Circle)です。南北戦争時にあったとされた秘密結社です。日本では、「金の輪の騎士達」や「金環騎士団」と訳されることもあります。これが発展して白人至上主義団体のKKKとなりました。源流は映画「天使と悪魔」を見てください。科学者の団体であるイルミナティが源流です。現在では、常温核融合、超伝導、地震兵器という要素還元主義の毒電波で世界を大混乱に陥れています。100年先を語るのは今日をちゃんと生きている人間だけです。
