Everything you need to know about Zika virus – symptoms to treatment

Published

on

New Delhi- Global health officials say the Zika virus, linked to severe birth defects in thousands of babies in Brazil, is spreading rapidly in the Americas and could infect 3 million to 4 million people. The race is on to develop a Zika vaccine.

Here are some questions and answers about the virus and the current outbreak.

How do people become infected?

The virus is transmitted to people through the bite of infected female Aedes mosquitoes, the same type of mosquito that spreads dengue, chikungunya and yellow fever. The Pan American Health Organization (PAHO) said Aedes mosquitoes are found in all countries in the Americas except Canada and continental Chile, and the virus will likely reach all countries and territories of the region where Aedes mosquitoes are found.

How do you treat Zika infection?

There is no treatment or vaccine available for Zika infection. Companies and scientists are racing to develop a safe and effective vaccine for Zika, but one is not expected to be ready for months or years.

How dangerous is it?

The PAHO said there is no evidence that Zika can cause death but some cases have been reported with more serious complications in patients with pre-existing medical conditions.

The virus has been linked to microcephaly, a condition in newborns marked by abnormally small heads and brains that have not developed properly. It also has been associated with Guillain-Barre syndrome, a rare disorder in which the body`s immune system attacks part of the nervous system. Scientists are studying whether there is a causal link between Zika and these two disorders.

How is Zika related to microcephaly?

Health officials have yet to establish a direct causal relationship between Zika virus infection and birth defects, but it is strongly suspected. Brazil has reported 3,700 cases of suspected microcephaly that may be linked to Zika. It is unclear whether in pregnant women the virus crosses the placenta and causes microcephaly. Research in Brazil indicates the greatest microcephaly risk appears to be associated with infection during the first trimester of pregnancy.

What are the symptoms of Zika infection?

People who get Zika virus disease typically have a mild fever, skin rash, conjunctivitis, muscle and joint pain and fatigue that can last for two to seven days. But as many as 80 percent of people infected never develop symptoms. The symptoms are similar to those of dengue or chikungunya, which are transmitted by the same type of mosquito.

How can Zika be contained?

Efforts to control the spread of the virus focus on eliminating mosquito breeding sites and taking precautions against mosquito bites such as using insect repellent and mosquito nets. U.S. health officials have advised pregnant women to avoid travel to Latin American and Caribbean countries where they may be exposed to Zika.

How widespread is the outbreak in the Americas?

The World Health Organization said Zika cases have been reported in 23 countries and territories in the Americas in the current outbreak. Brazil has been the nation most affected. Other nations and territories include Barbados, Bolivia, Colombia, Dominican Republic, Ecuador, El Salvador, French Guiana, Guadeloupe, Guatemala, Guyana, Haiti, Honduras, Martinique, Mexico, Nicaragua, Panama, Paraguay, Puerto Rico, Saint Martin, Suriname, Venezuela and the U.S. Virgin Islands, according to the PAHO.

What is the history of the Zika virus?

The Zika virus is found in tropical locales with large mosquito populations. Outbreaks of Zika virus disease have been recorded in Africa, the Americas, Southern Asia and Western Pacific. The virus was first identified in Uganda in 1947 in rhesus monkeys and was first identified in people in 1952 in Uganda and Tanzania, according to the WHO.

Can Zika be transmitted through sexual contact?

One case of possible person-to-person sexual transmission has been described but the PAHO said more evidence is needed to confirm whether sexual contact is a means of Zika transmission. The PAHO also said Zika can be transmitted through blood, but this is an infrequent transmission mechanism. There is no evidence the virus can be transmitted to babies through breast milk.

What other complications are associated with Zika?

The WHO says because no big Zika outbreaks were recorded before 2007, little is known about complications caused by infection. During an outbreak of Zika from 2013-2014 in French Polynesia, national health authorities reported an unusual increase in Guillain-Barre syndrome. Health authorities in Brazil have also reported an increase in Guillain-Barre syndrome.

Long-term health consequences of Zika infection remain unclear. Other uncertainties surround the incubation period of the virus and how Zika interacts with other viruses that are transmitted by mosquitoes such as dengue.

monsoon damage in himachal pradesh 2021

Shimla-Monsoon continues to pummel Himachal Pradesh with deadly ferocity, leading to more cloudbursts, landslides, and flash floods. Several rivers and rivulets are in spate. Incessant rains could bring more destruction as the HP Meteorological Department has forecast widespread heavy rains till August 1st. While a red alert was issued for July 28, an orange alert has been issued for July 29 and July 30 and a yellow alert for July 31st and August 1st.

An advisory has been issued for locals and tourists to not venture near the river banks and avoid unnecessary travel as incessant rains could lead to more landslides, flash floods, and uprooting of trees.  However, tourists could be seen resolutely ignoring these warnings and partying near river banks and water bodies.

As devastation unfolds, the death toll due to monsoon induced calamities has reached nearly 200, while damages to property were assessed to be in hundreds of crores. Over 350 roads, including Manali-Leh, Pathankot-Chamba, and Shimla-Kalka, were blocked due to landslides.  Half a dozen bridges, as many as 30 houses and several vehicles were destroyed. Hundreds of tourists were reportedly struck in Lahaul.

After a flash flood in Dharamshala, a massive landslide in Shahpur constituency, and a horrid rockslide in Kinnaur district that killed nine tourists and injured four people, a cloudburst triggered a flash flood in Lahaul-Spiti district on Tuesday that washed away over a dozen of people, who were said to be labourers.

According to the Director of the State Disaster Management, Sudesh Kumar, at the time of writing this report, seven bodies had been recovered while four others were missing. The cloudburst occurred over Tonzin nallah in the Lahaul region of the tribal district. Rescue operations were in progress to trace missing persons.

A team of the National Disaster Response Force, which was on its way to Lahaul-Spiti through road, remained stuck in Mandi for several hours.  

On Wednesday morning, cloudburst was reported in Kullu district resulting in deluging of Bhramhaganga – a tributary of Parvati river. A  tourist, a 25-year-old mother along with her 4-year-old son, and a hydropower official came in its spate and were yet to be traced. Beas river was also in spate and people living in shanties on its bank were evacuated.

Rackham area in Kinnaur district also reported heavy losses due to a cloudburst on Wednesday morning.

While a rockslide killed one person in Chamba’s Saluni, a helper tagged with a JCB deployed for clearing Bharmaur-Pathankot National Highway was swept away by gushing waters of a nullah on Tuesday night. His body was recovered on Wednesday.

In Shimla, a landslide between Vikasnagar and Panthaghati crushed a vehicle and caused damaged to some others. Gumma khud in Chirgaon was also in spate and reportedly swept away a bridge and about four vehicles.

Dharamsala received the highest 122 mm of rain, followed by Una 119 mm. In Solan district, Kasauli and Nalagarh also received over 105 mm rain. 

This widespread destruction has worried climatologists and environmentalists who are linking increased instances of landslides and cloudburst to environmental degradation and destabilization of hills due to developmental projects, including cutting of hills for widening of roads, construction of four lanes, hydropower projects etc.

vaccination of youth in himachal pradesh

Shimla-Himachal Pradesh has reported a rise in daily casualties during the last three days. While 437 new cases were detected, 10 persons succumbed to the infection. in the last three days. According to the HP Health Department, state’s positivity rate for the last week – from July 5-July 11- was 1.0. Compared to a total of eight deaths in the entire week, Himachal has reported 10 deaths in the last three days of the ongoing week.

The State’s Covid death tally has now reached 3486. The number of active cases was 1150 on Thursday. The daily sampling remains between ten 10,000 to 15,000.

The state government has further discontinued vaccination for the 18-44 age group till 22 July. However, vaccination of other groups will continue. 

Himachal’s tourist spots continue to receive a large number of visitors daily. During the last month, after the HP government lifted all restrictions on inter-state movement, tourists had been over-crowding popular tourist destinations, especially Dharamshala, Shimla, and Manali, to such an extent that the Union Health Ministry, as well as, the Prime Minister had to warn states over the violation of guidelines regarding the “Covid-Appropriate Behavior”.

As both locals and tourists were observed to have become carefree and caring a little about social distancing or creating large gatherings, the state government on July 14 issued a fresh advisory to follow the “Covid-19 Appropriate Behavior” (CAB) to mitigate the third wave.

However, a widespread lack of awareness has been reported, due to which the public is not taking the warnings of the third wave and CAB guidelines seriously.  

In several instances, the state government found itself helpless in preventing large gatherings and violation of CAB guidelines. Over-crowded buses and carriage vehicles, for instance, is a common scene against the permitted capacity of 50%. The health experts had been insisting that successful implementation of SOPs at the mass level is not possible without the co-operation of the people. However, the current methods of the state government for creating awareness has failed to appeal to the majority of the people, which is making compliance of guidelines next to impossible.
